5 mic kit for the DD? If the mics are anything like the price of the ones with the MC-12, I expect that to cost a fair bit :)

I have done some more tests.

1) No EQ on the DD-18 at all, followed by Room EQ on the MC-12. Good results

2) EQ on the DD-18, followed by Room EQ on the MC-12. Reasonably good results. Similar sound to the one above..but actually I give the edge to 1)

3) MC-12 Room EQ first, then DD-18. Strange results with a sort of "muddy" quality to the bass.

4) MC-12 Room EQ first, then DD-18, then MC-12 again. Seems to produce an almost identical graph to 2). I wondered if a continuous iteration would home in on an optimal result, but I don't think it makes a real difference.

So, although I still want to play some more, I have finalised on a result where I am not using the DD-18 EQ facility at all! :) Can I send in the mic for a refund and recoup some costs! Just kidding...but it seems a shame if the best solution in my room/set-up means I don't get to use all the features :)

You know, someone else with a D2 and a DD-15 came to the exact same conclusion. The sub sounded better and tighter when the Velo Eq was bypassed (Preset #6). I'm going to try that to see if mine sound better when I bypass the Velo Eq.

That will be interesting. But do you mean you will re-run the D2 ARC after setting the DD to EQ bypass?

I have a theory about this effect, which will vary from room to room. The MC-12 EQ looks for room modes. Essentially this means it looks to reduce the decay time of the bass, rather than aim for a flat response. When I am trying to flatten out the DD-18 EQ by reducing the peaks and smoothing out the valleys, I may be affecting the room modes (as in their intensity, obviously a room mode is defined by the room and speaker placement) in some way. In my case perhaps it was doing so negatively, so the MC-12 was then having to compensate even more.

Accentuating room modes will affect the perceived "timing" of the bass, but in particular, and Lexicon's emphasis, a heavily decaying bass sound will "cloud" the higher frequencies, such as vocals, making them sound less clear. I watched a concert of Massive Attack at the Royal Festival Hall in London. The acoustics are most definitely NOT designed for bass heavy music. The lack of acoustic control was extremely evident. When the vocals were singing solo, they were clear, precise and well defined. When the bass kicked in, although the vocal volume was still perfectly adequate, the heavy amount of bass decay clouded the clarity of the vocals, making them almost non-intelligble.

Hi Curt,
I recently moved my DLS-5000 180 degrees and it now faces the wall.

Since space and placement choices are limited, where and what direction would you recommend I place my sub?

Here are some pics of the sub and the area it is in:

The last pic shows where it is currently at.
I noticed more bass in this position but also more resonance, etc.

Should I move it away from the wall and place it in the middle of the wall cutout ?

Thanks!

Set the DD to Preset #6 which will bypass the EQ. Next, use the good old Radio Shack SPL Meter to calibrate the sub's volume to 75db. Now, run ARC and see what the graph looks like.

When set to auto turn on should the red power light on the rear panel be on or off when there is no signal?

When in standby mode after no signal is detected for 15mins, should there be any sound from the sub up close? I do hear a sound of air/wind noise:rolleyes:

In 'standby', the red light will be on. When playing the light will be green, it should change to red after 10-15 minutes. With your ear to the speaker there could be slight noise in 'standby.

This is not the MiniVee

curt c

07-02-08, 07:50 AM

Hi,
The MicroVee is different. With the MicroVee, the red light is on when the unit is active. After no signal for about 10 minutes, the light should decay and the sub will be in the standby mode. I just tested one and the light went off in 7 minutes with the switch in the 'auto' (active) position. If your red light continues to stay on with no bass input, then either the unit is not operating correctly or there is enough current flow in your system to keep the light on. Disconnect the input cable to the sub and see if the light goes off in about 10 minutes. Also try the switch in the 'on' (inactive) position in case your auto on/off switch is designated backwards.

having problems setting up my velodyne vrp-1200 to my onkyo 850. Unable to get the sub to work. used the y-splitter, sub set to yes. trying to connect onkyo line level jack out to velodyne speaker level inputs. can anyone give me step my step help?

ransac

07-02-08, 11:06 PM

Look on page 21 of the Onkyo manual. It shows where how to connect the sub.

Velo is high on using a Y splitter, but it isn't necessary, but it won't hurt and can help with the auto on function.

From the VRP1200 manual:
Inputs
Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor (such as LFE out), linelevel crossover, or receiver with pre-amp level outputs. When using the line level jacks, some receivers may not provide enough signal to have the unit’s auto-on feature operate properly.
Additionally, this lack of signal may also cause the subwoofer to produce less output than it is capable of.
To alleviate this condition, we recommend the following steps:
1) If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED
– never use just the left or just the right input. If the subwoofer’s input comes from the
LFE channel of your receiver, use the included “Y” splitter to divide the single input into
two inputs for the Left and Right subwoofer inputs. If using line level connections from
a preamp or signal processor, use both Left and Right inputs from your preprocessor or
preamp and connect them to the Left and Right inputs on your subwoofer.

And you should be using the Line Level inputs on the Velo, not the Speaker Level inputs.

hi everyone well i have a Velodyne CHT-12 for about more then 3yrs now and i dont know if their is such a problem or if i dont know about sub in HT but i find it that it has too much bass while i like the bass it produces it just doesnt sound accurate to me

i would also like to understand if more htz better or worse? and what they mean example 80hz 100 hz or what people seem to like low numbers such as 20-25 hz why? please help

also i have infinity beta floor stand towers as my fronts (beta 50s) i think its 8" woofer driver and my receiver is onkyo tx-sr701

the reason i have a worry or a thought is because the sub was a openbox and that can mean it was either a store demo or customer return (from ciruit city)

i have warranty with CC but honestly i dont know if the sub is funtional 100% and like they say it if it anit broken dont fix it.

but i would like to know or understand what is the essitnal ideal of the sub? low htz?

fianly what replaces the Velodyne CHT-12 ? are the velodyne better since the cht 12 era? or the cht 12 was at its best time?

should i match my infinity beta speakers with infinity beta subs?

space / size is not an issue and im cosern about powering it right? enough watts? powerd amp? confused help! my living room is over 11ft closed area only a door wall to kitchen and cartpet floor

I purchased a vrp-1200 from CC new in the box and it was not working, so I bought a vrp 1000. to me it sounds good, I hear it but I do not feel it. Will installing two of them let me feel the bass. In this and other forums they are saying I would have been better off buying a hsu, or a eD or a SVS sub. They are saying the velodynes I purchased is near the bottom as far as subs performance and price. They are saying the velodynes I purchased will never give me the low rich full bass sound. Is this true? Had to pay $40 for a warranty at CC to get my sub repaired. Paid it because velodyne requires I pay shipping to the repair center, the cost would have been about the same to ship it vs buying the warranty. Should I take them back and buy a velodyne sub they will give me a better performance on the low end? Is this a continious thread where I can only post a reply? Could not find the icon for a new thread.

07-05-08, 12:23 PM

Hi,
This is an 'Official Velodyne Support' thread which differs from a regular 'chat' thread. Since Velodyne would only have you ship the amp (not the subwoofer) for a repair if necessary, the cost is quite low. The important consideration for selecting a subwoofer is room size, so I suggest you go to; www.velodyne.com then 'which product' and then 'sizing wizard'. Determine your total cubic displacement counting all rooms if there are permanent openings, and then enter the cubic displacement number for subwoofer recommendations. If you have a medium to large area and want deep powerful bass, the DLS-5000R is truly a great performer. You can always email me direct, or better yet call during the week for individual advice on your needs and application.

What do you mean send in amp, not sub? my room is over 3,000 cu inch, I have been on the velodyne site and they recommended several subs including the vrp-1200. I just want to be sure I am buying the right sub to set up my home theatre room at an affordable price. I want it hear and feel the bass.

curt c

07-05-08, 01:15 PM

Hi,
For your room my first recommendation for deep (feel-it) bass is the DLS-5000R, after that it would be the DLS-4000. If your budget is at entry level, then the VRP-1200 is a good way to go. Keep in mind the subwoofer is the most (IMO) important element in the sound chain, so budget accordingly. For repairs, the amplifier is pulled out (a simple process) and returned, not the subwoofer.

Hi Everyone,

This is my first go at building a "quality" home theater system. As such, I was hoping to get some advice on a subwoofer that'd be a good match for my system.

The set-up is for my bedroom, which measures 11'6'' x 13' with 9 ft ceilings. This is what I have so far for the system.

Sharp Aqous 46'' 1080P
Denon AVR 888
RF-35 Klipsch Towers
RC-35 Klipsch Center Channel

I'll be using my system mostly for home theater (movies, cable, gaming) with some music listening as well. Since it is a bedroom set-up, space is somewhat important. I simply don't want something that's going to look huge and take up way too much space.

I had considered a Mini-Vee (8''), but I wasn't sure if that was my best option.

Any suggestions?

curt c

07-05-08, 05:27 PM

Hi,
With your high efficient Klipsch speakers, you need to avoid any of the small sealed box subwoofers like the MiniVee-8 or MiniVee-10. They can't play near loud enough to keep up with the Klipsch's especially for H/T. First choice and best match for your speakers is the DLS-5000R, fallback would be the DLS-4000R.

Hi Curt,

First I have a recommendation for Velodyne.
Nowhere on the manual is expressly written that they recommend setting up a DD-18 in manual configuration.
They just explain both the techniques and that's all.
I have owned a DD-18 for more than 8 months now and never bothered using the manual config. I was happy with the results.
Yesterday I was set to reconfigure my whole system as I recently purchased an Anthem D2. So I decided to give it a try and use the manual configuration.
There is no comparison whatsoever.
I used all the settings and fine tuned everything, watching as I was doing it at the graph and the curve changing shape.
The result is stunning.

One more thing. In the manual there are some recommended settings for THX Ultra2 processors.
One value cannot possibly be set as described:
Low Pass Crossover Frequency: OFF
Low Pass Crossover Slope: 6 dB per octave
These 2 can't go together, right?
I mean you cannot have the freq set to OFF and the slope set to any other value than OFF too.
So what are the recommendations for Ultra2 that works?

Thanks

curt c

07-06-08, 11:37 AM

Hi,
Well actually there are three EQ foremats. There's 'Self' (3-2-1), 'Auto' and 'Manual'. I tend to think of them in the old Sears Roebuck tradition of Good, Better and Best. Certainly the Manual offers the most capability and flexibility including 'parametric'. It's great to hear the results you achieved in the Manual mode.
The THX-Ultra2 setting for the crossover is turning the DD's crossover to 'off' and of course that also eliminates the crossover slope. Your crossover would be set in your pre/pro or receiver.
Thanks for the suggestions and we will try to do a much better job on the next manual.

Hi Curt,

I am sorry but I didn't quite understand what you meant here.
So what I did is note the crossover frequency the Anthem D2 has set for the sub which is 120 Hz. I set this frequency as the Low Pass Crossover Frequency, and I set the Low Pass Crossover Slope to 6 dB per octave, as advided for THX Ultra2. But i don't really understand what I did here.
Is it ok? Can you clarify that for me?

Thanks

07-06-08, 01:26 PM

Maybe you need to talk to Anthem. My recommendation is set the crossover in the Anthem, not the DD. Bypass the crossover in the DD. That's also the THX recommendation.

Most advice says to set speakers to SMALL in the receiver, set the crossovers to 80 in the receiver, and set the sub to DIRECT.

However, the Energy Take manual suggest setting speakers to LARGE on the receiver and setting the sub-woofer itself to 80 hz.

Here's the setup:

Rcvr: Sony STR-DA5300ES
Fronts: Energy Take TWRs
Center: Energy Take FPS
Surrounds: Energy Take LCRs
Sub: Velodyne SPL1200-R using LFE (1) input from rcvr's LFE out
Positions: Everything but the sub is wallmounted. The sub is just to the right of the right-front. The fronts and a 52" Bravia are wall-mounted high but not way high.

Currently, I have the receiver set for all speakers to LARGE, and I have the Velo set to DIRECT. That shouldn't sound good but it does!

I *think* it results in the lows playing from the Energy speakers AND the sub, rather than "rolling" or "blending" at some frequency point.

FYI, I just traded back a new Minivee for the SPL1200 and I'm much happier. It's a small room but the MiniVee kind of "announced" itself, like "boom - here goes the sub-woofer". The SPL1200-R (as set up now) just kind of adds bass and there's no "sub is now kicking-in" effect at all, even when playing very loud with a lot of subwoofer.

When I set the speakers all SMALL on the receiver, and the x-overs to 80, it sounds very similar.

Another factor might be the Sony's Cinema processing, and maybe the DVD's encoding are sending specific signals to the sub anyway. (???)

Advice appreciated.

I have purchased 3 subs, two vrp-1000's one vrp 1200. For now I am trying to hook up two vrp-1000's. I will use the vrp 1200 when I get it back from repairs. I connected both of the 1000's with a y-splitter to my onkyo 805. One sub is next to the tv the other is 20 feet away next to my fireplace...(not in harms way). The set-up seems to increase the bass in my kenwood towers and center and did nothing for me at the other end of the room. Did I degrade the strength of my bass signal by connecting it to two subs and is the one sub 20 feet away getting a weaker signal. I hear the bass coming from the front and nothing from the back. By the way the 1000 sounded great as a stand alone. I ran the tone test, when the test tells the sub to make a noise only the sub in front sounds off. Can someone tell me how to properly set up two subwoofers?

07-07-08, 02:03 PM

Hi,
The 'Y' out of the receiver is a correct way to hook up the subs. From what you're saying, it appears the rear sub is not working. Reverse the hook-up and position of the two subs to see if the rear one works up front. Maybe your rear cable or the 'Y' is at fault. A distance of 20' is not a problem. If this isn't clear, give me a call.

I have the VRP-1000 that was struck by lightning...long story and bad result. Anyway, I have found the 2 fuses on the amp and have replaced them as they were blown and I was hoping for a quick cheap fix. The fuses blow as soon as it is plugged in so it is in need of repair.

Hello. This is my first post as a new member.
I have a 4-year-old Velodyne SPL1200 sub. Up until now it has been working perfectly. Today I noticed that there is no output. The only indication that anything is working is the blue auto-on LED will activate when a signal is detected. But no other signs of life. I switched the power to off and unplugged, hoping to reset the unit, but still nothing. I checked the fuse inside and it looks fine. Any ideas what it might be, or what I could check?

Hi,
I would certainly recommend calling the 'Takes' small. I have no idea why Energy would recommend otherwise. I'd check with Energy. Putting deep bass into small drivers is not a good thing. Maybe they're using a built in filter or mechanical roll off. Even so I see no reason to call them large. I agree the SPL-1200 is a very wise choice, it has a lot more reserve than the MiniVee.
Thanks,
Curt (928) 858-4430 or curt@velodyne.com

Thanks for the advice. I am loving the SPL-1200.

Any suggestions on the crossover freq's? The Sony receiver will let me set them individually for all - fronts, center, surrounds.

And is there ever a (good) reason to use different crossovers for surrounds than for fronts?

Hi,
What size woofer do your 'Takes' have and what is the rated frequency response? What crossover choices does the Sony receiver offer? The old 'Take Fives' had tiny 3" woofers. That may have changed. If all speakers are the same then you would normally use the same crossover. If your surrounds and or center were smaller or different that would often call for a different crossover.
thanks,
Curt (928) 858-4430 or curt@velodyne.com

4 x 3-inchers in each Take TWR, 1 tweeter, and "2 bass ports" (they serve to make the speaker look bigger :) ).

The center Take FCR has the same set of 4 3-inchers and one tweeter minus the two bass ports.

The surrounds Take LCRs have 2 of the 3-inchers plus one tweeter.

I'll check the published frequency response.

The Sony offers 40 to 120hz on crossovers.

If I crossover too high on the surrounds under the theory that they are the smallest, I lose all the directionality effect on explosions etc. due to the lows going off the sub.

I'll get the frequency response info on the Take's and follow-up.

07-09-08, 12:47 PM

Hi,
All your speakers are close enough to take the same crossover point. If you tend to listen loud and watch 'action type' movies, I would use 100hz as crossover, second choice would be 80hz. Either should work fine.

Hi

Sorry for this probably dumb question but I am not a technical guy...
Could I connect the Line-Out of my Apogee Duet (external DAC) to the Line-In on my DD-10?
The thing I know is that normally you connect an Amp Pre-Out there and this signal is not amplified whereas the Line-Outs of source devices like CD-Player or my Duet would be ampliefied already, right? I could regulate the volume of the Line-Out with my Duet to a very low level, but I am not sure what it would mean to signal quality and more important if it could harm the DD-10 anyhow...

The goal of this would be that the DD-10 filters the low signal out and passes the frequency above 80Hz to the Line-In of my Amp. Silly?

The reason for this idea is quite complicated but I think not really necessary to answer. But I can explain if someone is curious...

Many thanks.

curt c

07-10-08, 09:38 AM

Hi,
I don't know anything about the Apogee Duet, but assuming it's output is analog, you could try it. The output signal would need to be strong enough that you don't run the volume of the DD way up.

Hi Curt,
My Yamaha RX-V663 receiver will not let me individually adjust the crossover for the center channel to 80hz and the front channels to 60hz.

So since the center channel can only go as low as 80hz, should I just adjust the crossover to the 'Direct' setting or to 80hz, on the back of my DLS 5000R?

I ask because I noticed there is no resonance from the sub, when the crossover is set to 50hz (bottom limit of the Front speakers) on the DLS and 80hz on the receiver.

Theoretically, there is a 30hz gap but it sounds good to my inexperienced ears.

Thanks for your support!

Hi,
I would set all the speakers, including fronts, to 'small', crossover in the receiver to 80hz and sub to 'direct'. However if you prefer your current setting there's nothing wrong with that. I always go with what my ears tell me.
Thanks,
Curt (928) 858-4430 or curt@velodyne.com

Hi Bruce:
I just traded up to a new DD12. I'm curious as to where to hook up a 12v trigger? The manual says that I can turn on the sub via a 12v trigger, and the onscreen menu allows me to opt to have the sub turn on via the 12v trigger. I know that this feature works because when I switch it to the 12v trigger from the auto on/off mode, the sub turns off (because it is waiting for a 12v signal). However, of the numerous plugs in the back, I cannot find one that is specifically labled as a hookup for a 12v signal. And ditto for the Rear Panel Connections schematic in the Owner's manual. Any ideas?
Thanks,
David

07-10-08, 06:26 PM

Hi,
The 12 volt trigger is wired to pins 7 and 9 of the RS-232 out port. It's in the manual, just a bit tricky to find.
Enjoy your new DD-12.

07-13-08, 11:25 PM

Hi Curt or Bruce:
If I use a 12v trigger to turn my DD12, would the sub still give that little audible "pop" it gives to indicate that it is active when it receives its first bass note? I don't like that "pop." I especially don't like it when the sub goes inactive when the music is quiet or has no bass and then "pops" again to tell you that it is back in action. Is there any other way to disable it, like I can the light?
Thanks,
David

Yes...I also wanted to eliminate that little "pop" with my DD-18. I have found that the sensitivity threshold of the DD-18 isn't high enough, so sometimes it goes into standby a little too easy...and then you hear the little pop when it finally gets enough bass to trigger it.

I don't want to leave it on all the time either, so the trigger method may be the way forwards.

Post, calibration, the DD-18 volume is at 10, and the Lexicon MC-12 sub level is at -7.5dB. This seemed a fair balance, as otherwise the DD-18 volume would be seemingly too low, or the MC-12 level is so low that the SNR starts to become a concern and it wouldn't trigger the DD-18 at all....I would have thought.

curt c

07-14-08, 01:24 PM

Hi,
The Lexicon volume looks way low to me. I'd raise it considerably and lower the DD and see if that helps. We have many DD-18's running well below '10'.

I have a DD-18 about 3 years old (no warranty) that started doing something very strange. When I first turn on and begin to play system I hear some awful distortion even at low volumes. It makes like a cracking, popping sound. Basically it sounds like the speaker is completely blown. But after just about 2-3 minutes it goes away and everything plays fine even at high volume. If I turn sub off and back on it still works fine. However, if I leave off for say 5-10 minutes and then turn on the problem repeats. Its almost like it just needs to warm up before I can play without distortion.

Does anyone have any suggestions? What would cause this? Stuck servo motor? I expected better from a $5K subwoofer.

curt c

07-14-08, 09:12 PM

Hi,
I am indeed sorry that your DD-18 has problems. There is no 'servo' motor to stick. The servo section is an electronic feedback circuit, not a motor. It sounds like some amplifier capacitors have gone bad. You have been in touch with Velodyne service and they gave you an estimate for repair. The amplifier section is all that needs to be sent in.

Curt, the answer to this may be buried in this thread somewhere but I cannot find it. If the DD-18 is on but not currently producing any sound, I can hear a very faint "whirring" sound when my ear is placed close up to the front of the sub. It almost sounds mechanical, like a fan or something. What is it? Is it just noise in the system?

Hello,

Ever replaced a front panel on a DD-18? Well, this is what I've got to do now.
I just received from Velodyne a replacement front panel.
I expected to only get the grill, which is very easy to replace, but no.
I got a complete set with the wooden frame too, which very nice.
The problem is that the lit brandname at the bottom (led lit) is attached to the frame and from the frame there is a small cable with a plug at the end.
I almost dismantled the installed original frame only to notice that this small cable actually disappears into the sub's box.
I am scared of pulling this cable or anything, so I rolled back th procedure.
Now I need your help.
Can this cable be detached and reatached from the front or do I need to access it from the inside of the sub which means I have to dismantle the amplifier at the back?

Waiting for instructions.

Thanks:)

I own two DD-15’s.

I read in an article somewhere that when using two subwoofers in the same room that the Polarity of one subwoofer should be set to “+” and the other set to “-” otherwise the outputs may partially cancel each other out.

Is this true?

curt c

07-28-08, 06:12 PM

Hi,
Well depeding on placement I suppose in certain situations which I've yet to come across, it could happen. More likely there will be much more cancellation with the two set at opposite polarities. It is easy to verify. Sit at listening position and with the remote, reverse the polarity of one of the DD's. Is the bass louder, the same, or lower? Or better yet with the on-screen monitor display look at the signal sweep with both playing in the positive mode and then reverse the polarity of one of the units and see what differences there are. One of the big problems is what is true at location 'A' won't be true at location 'B' in the same room. When I use two subs they are almost always both on the front wall and both 'positive' polarity. Again, with the on-screen display you can see what's happening.
I'm back and inviting calls or questions.

I have some confusion on the update for the SMS-1.

In this thread it indicates that the instructions for the software update are on the Velodyne website. For the SMS-1 I can find the latest software version 2.1.3, but no instructions.

When I open the version 2.1.3 on my computer it indicates Velodyne Digital Drive update, not SMS-1 update. In addition, there are no instructions when I unzip the file.

Where are the instructions to be found? Maybe I am looking in the wrong place on the website.

Curt,
I own two SPL-1500R subwoofers that I currently have connected to my AV processor via its LFE output. My main speakers are full range, my center and surround speakers are limited range speakers. I’ve recently been contemplating connecting my subwoofers in stereo instead of by the LFE output of the processor for 2-channel listening (and still having them connected to the LFE output for surround sound). I could run the right output of the AV processor into one subwoofer and the left output of the AV processor into the other subwoofer, then run the output of each subwoofer back into the amplifier for 2-channel listening.

1. Would stereo subwoofers sound better than having both subwoofers connected to the LFE output when listening to 2-channel music?

2. Would the auto EQ function still work well if each channel is separately connected to a subwoofer and speaker?

3. What crossover point would you recommend to maximize punchy bass quality? Is 100 Hz or 150 Hz crossover too high?

4. Any other considerations?

curt c

08-11-08, 11:22 AM

Hi,
1) This will always be a topic for debate. IMO, no and in most software the bass is already mixed to mono. In a dedicated two channel system I would hook them up as stereo but in a A/V stem I would go with mono. You can certainly try both methods.
2) The auto-eq will work either way. The sub supplies the signal sweep for auto eq and nothing else should be playing when doing the auto-eq.
3) 80hz is a good crossover point for most systems, 100hz and especially 150hz is usually too high unless very small speakers require it.

Hi all,

I was wondering.... does anyone know where I might be able to find a schematic for the amp that is in my SPL-1000? I had my electronics guy diagnose the amp and he concluded that the output devices are toast, but he isn't able to proceed with the repair since the ICs have had their part numbers rubbed off.

He said if I can track down a schematic he'll be able to fix it for me, so here I am..... Also, I should add that I tried the local authorized velodyne service depot, and they quoted a prohibitively expensive price to fix the amp (3x what my guy quoted) and I'm assuming it would be even more to send it across the border for Velodyne to fix.

08-11-08, 03:03 PM

Hi Curt,
When you say Velodyne services direct, do you mean Dave Santos?

I had originally contacted support (via the online ticketing system) inquiring about obtaining a schematic. Dave emailed me back this morning saying that schematics aren't available, and gave me an RMA request form. I emailed him back trying to get a sense of how much such a repair might cost but haven't heard back from him.

I suppose the best route is to just pay Velodyne to fix the darn sub. It'll still be way cheaper than buying a new one.

On an unrelated note, what may have led to blowing the output on the sub amp? I would guess heat could be a culprit, but the environment the sub is in isn't anything out of the ordinary, and it was never taxed very much; I kept the volume at reasonable levels and the room isn't overly large. The amp never felt hot to the touch or anything.

Hi,
Try service@velodyne.com or (408) 465-2800, ext. 2848 for an estimate and RA.
The class 'D' amp puts out very little heat. I have no way of knowing what caused the failure unless the area is too large for the SPL-1000. Selecting the proper size subwoofer is very important to subwoofer performance and life. See www.velodyne.com, then 'which product' and then 'wizard' for sizing recommendations, or call me direct.

I can buy a used HGS-15 in good condition but with only 3 month warranty.

Hi,
Buying used always carries some risk. Who is furnishing the 3 month warranty? We still service the HGS-15 and it's an excellent subwoofer. If your area is large, you may need at least the 15". Have you calculated cubic displacement? If the room is small with no permanent openings then the DD-12 with it's equalization capability would be an excellent choice. If possible, I suggest you call me direct and we can go over all the issues involved in the choice.

Thanks curt,

I am living in tokyo, that's why I am a bit worried about service.
The 3 months warranties are from the shop. That's a serious shop, the number one in Japan, I bought many used stuff there and never had problem.
They sell the HGS-15 around 1500$.
My room is around 20 meter square. I am using a ELAC 211.2 now but I am disappointed with it, especialy for movie.
The DD-12 is around 3000 $ here and hard to find.
In japanese magasine, they never talk about velodyne, they always claim the best sub is the eclypse 725SW.
I am using no center speaker, 100 inch screen with two AAD 7001 for the front. I use a Pioneer LX-90 (SC-09 in US I think) for amp.
If I understand well, the HGS-15 cannot accept signal from both speaker input and LFE at the same time (ELAC sub can). So I am planning to use a RCA selector with one entrance the pre-out of my amp and the other entrance the LFE.
When I listen to music, I switch to the pre out. And for movie, I switch to the LFE
The LX-90 cannot do bass management in pure audio mode from analog signal without converting it to digital. That's why, the only way to send the bass to the sub with pure analog source is to do like this.
Do you agree it will work?

One more last question, I rode in some forum, that a lot of HGS-15 got trouble with their amp section after 5 years. Do you think if I have a trouble, it should arrive within the first 3 months?

Thanks a lot

Hi,
You have close to 2,000 cubic feet so either sub should be fine. There have not been any significant problems with the HGS-15 amplifier and service is still offered for the unit. Your proposed hook-up is good. The DD sub will convert your analog signal to digital for bass management purposes. Maybe the dealer will let you test the sub in your system.

Hi Curt,
Got a question regarding the side-effects of powering off my DLS-5000R every night.

I use the remote to turn it off every night to conserve electricity (expensive in California) and turn the sub back on again when needed.

Will this daily power recycling decrease the life of the power supply or related components?

Thank you!

curt c

08-19-08, 02:22 PM

Hi,
When you turn it off using the remote, you're putting it in 'standby' which is what happens in the auto on/off mode. In 'standby' it consumes very little power, about 25 watts. The only way to turn the sub (totally) off is the main power switch on the amplifier plate. Turning it off and on with the power switch should not decrease the life of the components.

Curt,
Before I go to my question, I would just like to say what a class act you are... Unlike many companies who don't care very much about support, you are here in the front lines taking questions, giving advice, sometimes taking heat (undeservedly IMO) and never complaining. This reflects excellent upon Velodyne, and given this level of service I am one of your most loyal customers.

I have the CT-150 and LOVE IT!

I have recently decided to go with a 2 channel setup in addition to my 5.1 system driven by an Onk 805.

My preamp is an Odyssey Candela with an HT bypass - nice feature.

My question is: for movie viewing, I have the CT-150 connected to the Onk, then the Onk's front preouts going to the Candela, out to my 2 channel amp and to the speakers (Monitor Audio GR20).

I want to incorporate the CT-150 into my 2 channel system in addition to the HT and here is what I was thinking:

Onk front preouts to the preamp, from there to the CT-150 and out to the 2 channel amp.

Would I set the xover on the sub to IN?
Also, have the phase set to 0 and adjust accordingly?
Toggle switch to audio?

My speakers are not bass efficient. Would I set the Highpass to 100? How about Lowpass?

Since it's a long chain, would the bass from the HT still be reproduced properly?

Thanks Curt, and sorry for all the questions...
Danny

curt c

08-22-08, 01:20 PM

Hi,
If I follow correctly, it would appear to work. You could certainly give it a try.
1) Set the sub X'over to in.
2) Phase at '0'.
3) Audio or Video is okay. Video is about 1 db louder, otherwise the same. I'd just leave it on Video.

Hey, I have a Velodyne CT-100. It was hooked up to an NAD reciever for a couple years trouble free. Recently my NAD was fried. I purchased a new reciever and hooked the sub to it. The reciever turned on but sound never did come from the speakers. Could the powered sub be the cause of the trouble? I returned the new reciever, saying it never worked and did not hook the sub to the replacement, just in case.

Anyway, I would like to use this sub if it is safe. Is their any way I can tell if the sub is safe to hook up with a volt/ohm meter? I hate to spend money to have repaired if nothing is wrong. I would hate to buy a new one if it is still good. The sub does turn on and the fuse inside is good.

Any Help will be appreciated, I really miss it!

Hi,
If your new receiver was not programmed correctly, that could be the problem. The quick way to check your sub is, run the two analog (rca) audio output jacks from your DVD or CD player directly into the two rca input jacks of the Velodyne. Have the sub turned off and the volume to zero while making the connections. Then play a DVD or CD with some bass content. Turn the sub on and slowly raise the volume. If you hear bass the sub is fine.
If you need more, give me a call tomorrow.
Thanks,

Hi. I am putting together a new system consisting of Yamaha 3800, Paradigm Studio 40's front, Paradigm CC-590 centre and Yamaha in ceiling rears. I am looking very closely at the Velodyne SPL1000R for the sub. Would it be a good match for those speakers? If possible, I want to place it in a cabinet - nothing in front but surrounded on all other sides ( I can leave some space at sides/back/top). Will this badly impact the sound? Are there any other Velodyne models that can be placed in a cabinet like that? Finally, the other alternative set up is Monitor Audio GS 10 fronts with matching centre.

Thanks

curt c

08-25-08, 09:34 AM

Hi,
Many users install subwoofers in cabinets with excellent results. Since the front is open, you can chose from many Velodyne subwoofers, depending on your cabinet dimensions. Avoid the VX and VRP models which have a port in the rear. The key is selecting the proper size subwoofer for your room. The SPL's are excellent for this application as long as the proper size is selected. The SPL's will certainly compliment either of your speaker choices. I suggest you go to www.velodyne.com, then 'which product' and then 'wizard' and enter the total cubic displacement, including any permanent openings into other rooms and see what we recommend for your system.
Also feel free to call me direct and we can go over the possible options.

I own two DD-15's, which I love.

Is there any way to change the color of the video screen so that one subwoofer displays in Blue and the other subwoofer displays in a different color . . . say Green? I have both of my DD-15's hooked up to my Anthem D2, but I always have to unplug one subwoofer to be absolutely sure which subwoofer is being displayed on screen while make changes.

If no provision presently exists to set an alternative screen display color, I suggest a choice of several different screen display colors be added in a future software upgrade or at least that the serial number be displayed prominently on the CENTER of the first home welcome screen for those of us who own multiple Velodyne DD subwoofers.

I accidentally pressed the wrong buttons on the remote with my DD-18 and started some sort of calibration cycle.

soyuppy:

I assume that you have something like Audyssey in your pre/pro. If so, they almost always recommend that you setup the Velodyne first. Get the sub pretty flat then the Audyssey can do its magic on the sub-sat handoff.

In my experience, getting the handoff done right is tricky. I will try to find the link that the Audyssey thread has, but it supports the setup your Velodyne first. Then if the pre/pro returns a funny distance for your sub, do not be alarmed as it is computing the delay of the processing in the sub controller as part of the phase/time compensation.

giomania

09-05-08, 01:10 PM

I'm sure this has come up before. But can anyone explain how they approach their setup.

I have DD18 along with pre/pro that has auto correction.

I went through the DD18 setup and to try to achieve the flat FR line.
Then I went to my pre/pro and does the auto calibration.

So which one does what? Or which one should I've done first. Calibrate the pre/pro first?

Below is an excerpt from the Audyssey Setup Guide I created, located here (http://www.avsforum.com/avs-vb/showthread.php?t=795421&page=191):

G. If the sub has an EQ system, use it to tame large peaks before calibrating with Audyssey.
1. Narrow peaks or dips in the response below 100 Hz that are 1/3 or 1/6 of an octave wide can be improved—but not eliminated—by Audyssey Mult EQ XT.
a. In these situations, the built-in subwoofer EQ systems might be useful.

Hi Curt, i own an Intera 7.8 receiver and a DLS-5000R sub set at volume 25 and preset no.3 (jazz/classical).

My Integra AUdyssey doesn't give me enough bass for my taste, so should i:

1) Add more bass level to my subwoofer channel on the Integra
2) Raise the volume level to my subwoofer channel on the Integra.

My personnal feeling is #2 because option #1 effectively gives more bass, shaking bass but probably muddy bass. #2 rises bass volume but probably keep bass tighter.

Do you agree with me??

Thanks

I have owned a pair of HGS-18's for quite a few years now that I purchased new. An amplifier failed in one unit in the first few months and Dave S. sent me a replacement to install.

There is always a constant woosh sound present from the drivers that can be heard even from a 12' listening position. This is with no connection other than AC. Different outlets or power conditioners do nothing to alleviate this.

Do the new DD series suffer from this? Is there anything that can be done to rectify this on my HGH's?

I own two DD-15's which used to be located in a room under 5,000 cu ft. I've just relocated them into a room that has over 8,000 cu ft. when all openings to side alcoves etc are included.

I used to run the DD-15's at a volume of only 8. I thought I'd be able to simply rsise the volume levels of the DD-15's up to say 15-20 or higher to create the same "slam" but the result is some bloat and not near the "slam" as in the smaller former room.

I expect you may recommend that I sell both DD-15's to replace them with DD-18's, but what about if i instead just add a new DD-18 and end up with 3 subwoofers(1 DD-18 and 2 DD-15's)? Would that be equal to 2 DD-18's or better or worse? Would the best positioning of 3 subwoofers vs 2 be enormously complex? Would 3 subwoofers potentially reduce bad room nodes better than 2 or not?

Right now I have each of the DD-15's cabled to my Anthem D2 directly left and right. If I add a new DD-18 I would have to cable it off one of the DD-15's. Any problems with that?

Hello Fellow Velodyne Owners and Exec's! I wanted to drop in and report that a recent issue with my Minivee was resolved quickly and easily. My Minivee did not turn off automatically as advertised. I opened a Help Desk ticket online and received a response next day from David S. (Customer Service Manager). David provided me some experimental diagnostic tips which I tried and ultimately we agreed a Return Authorization was needed. To save me shipping costs, David explained the simple method for removing the amp and I sent it away. Within 24 hours of receipt, I got a call from Pete and we talked through the testing that I had done and, ultimately I received a new amp. After popping the new amp in, I am happy to report that it works great! I was very impressed with the personal service, speed and simplicity that defined my experience with Velodyne CS. The sub is great, and my after purchase experience was just as good. Please pass this on to David, Pete and the gang.

I had a question about the SMS automatic calibration procedure. I have two DD-15's deployes as L/R subs; I also have two JL Audio f113's (forgive me) deployed as LFE subs. I have an AVP with Audyssey MultEQ XT, but have not calibrated with Audyssey yet.

I have been using SMS for about a year and a half, and did not use the auto calibration feature when I set the DD-15's up.

The only thing I want to accomplish with SMS software is to tame any large peaks before I run Audyssey. Will the automatic calibration procedure do this alone, or will it do more? I suppose I can just try it myself, but I thought I would ask for some kernels of wisdom.

I hope my question makes sense.

Thanks.

09-19-08, 12:30 PM

Hi,
I suggest you call me. Since the SMS-1 is a mono device I assume you are using it with the JL's. All your subs have some (or more) room EQ as does the SMS. Until I know how everything is hooked up I can't really advise you well. First, I would EQ all four subs, one at a time. The DD's could just be done in a 'self eq' manner (3-2-1-). After that I would use the SMS in a manual mode and somehow if possible, have all four subs playing at the same level at 'mic' position, when this final SMS manual eq is being done. The DD's and SMS have three EQ modes. There is self, auto and manual. When you say 'auto' I'm not sure if you mean self (3-2-1) or real auto-eq.

Need some feedback and sub recommendation from you guy's as I'm planning on getting a sub in a couple of weeks or so.

My listening habits are roughly 80% movies, 20% music.

My theater room is a cement high rise living room 15'X12' with a eating space attached on a corner that measures 5'X8'. Ceilings 8' high.

My current 5 speaker set up:

2 pair of Infinity IL50 (each with a 10" 250 watt powered sub built in) L,R,SR,SL.

1 Infinity IL36C Center with my 10" 250watt Infinity sub connected to it for lower frequency reproduction on center channel audio.

I use a Denon AVR 4308.

I've had my eye on the SPL 1500R and the SPL 1200R. They look really easy to calibrate and set up. Is this true? This would be very important to me because...

The subs in my Infinity set up need to be manually calibrated with RABOS (handheld meter and online graph etc) and It looks like a PITA. I haven't done the calibration in the 8 odd years I've had these speakers as the calibration kit wasn't included with any of my speakers or sub. I will grudgingly be doing the RABOS calibration in 2 months when I order my Infinity dipoles so I can go to 7.1.

Thanks in advance!

curt c

09-21-08, 06:09 PM

Hi,
Yes the SPL-R's are very easy to set up. With your 4K cubic feet you would need the SPL-1500R minimum. I suggest you look at the SC series with a SC-1250 amp driving two passive SC-15 woofers. This is also a very easy system to set up and would provide the output and reserve required for your large area. I am currently on vacation and will be available for phone calls on Monday, Sept. 29th so feel free to call then if you need more info on this.

giomania,
Between your JL Audio f113s and Velodyne DD15s, which are your favorite subwoofers and why? Do the JL Audio f113s have more bass punch or articulation?

I like them both equally, and that may be due to the duties to which they are assigned. The DD-15's are deployed as L/R subs, and the f113's are used as LFE subs.

Given the DD-15's get more "air time" due to the handling of all bass frequencies from the other seven channels, I am glad to have the EQ option. I figure this helps a great deal to deal with room acoustics issues, which are most problematic in the lower frequencies.

I did not try deploying them in the opposite configuration. I just figured the 2500W amp and 4" excursion on the f113's would be able to move a lot of air, so I used them for LFE content.

The service dept of the retailer I purchased my FSR-15 from (Sep 1999)thinks the "amp module" is bad. He said he doesn't have schematics to repair the "amp module" to the component level, nor can he obtain a new replacement "amp module."

Symptoms are that unit powers on OK and plays music. However, when powered on with or without an audio signal, it intermittently pushes out the cone/driver and makes an "electronic noise."

I called Velodyne Service and left a voice message but have not heard back yet. I found this forum and notice posts suggesting that parts for the FSR series may no longer be available. Wondering if someone can enlighten/educate me as to feasibility of repairing my FSR?

Can the HGS-18 be driven with an external amplifier? Eliminating/bypassing the servo control which is to noisy on mine for me? I have had the amp out for warranty replacement on one unit after it failed. Would I be able to make a direct connecon to the driver? If this is possible would it still provide comparable performance to a non servo subwoofer if not driven to it's limits? I have retired the subwoofers as the servo noise is bothersome to me at the 12ft position. I spoke with David and was told an amp tune "might" reduce the swish noise. I would prefer to attempt to drive them with a quality external amplifier which I have.

I am not worried about warranty as it is far out of the coverage period.

Hi,
While you could drive the woofer with an external amplifier, the performance would not be very good at all unless you applied the correct amount of equilization for the lower frequencies. That also requires a very powerful amplifier. I certainly would not recommend such an experiment. I have two HGS-18's and there is no servo noise more than a foot or two away. The beauty of the Velodyne servo subwoofer is the powerful deep accurate bass they provide. I would recommend sending in the amplifier for a update. If you decide to power the driver with another amp check with David as to which terminals to use.
Thanks,
Curt

Curt,

I guess I will go and send in my amplifiers. The servo noise is quite audible "to me" on both of my HGS-18's from the 12' listening position during quiet passages. Not loud enough that one would think something is terribly wrong but annoying to me. If it's not on the soundtrack I really would rather not hear it in the background. I am the same way with fan cooled components.

It's possible that they may have become louder over the years I don't know. It is something I asked about when they were new as my other subwoofers prior and after the HGS-18's are dead quiet. I can always tell if one of my HGS-18's was left on when I enter the room.

I purchased Velodyne SC 1250 to replace my old Hsu 500A amp. When I swapped amp’s, I got a 60 hz hum. The Hsu amp had a grounded plug and there was a 60 hz hum. I used a “cheater” plug and solved the hum. The 1250 does not have a 3 way plug. The system is on a dedicated circuit. I do not have access to a different electrical circuit for the electronics. I have everything plugged into surge protectors. The hum is present when I bypass the strips and go directly to the electrical outlet.

I do not use a receiver, I have a stereo set up using a Conrad Johnson tube pre amp and PS Audio monoblock amplifiers. The hum exists when the only electrical component turned on is the 1250.

How do I get rid of the hum? I am unable to use the 1250 because of this problem.

I am the owner of a DD-15 which I purchased May 2007.The unit is emitting a loud cracking sound whenever it is powered on. I have disconnected all inputs so that only the power lead is plugged in. I know the unit is definately faulty.

My problem is that in Australia I have no where to take the unit for warranty repairs. I'm sure that you are aware that Velodyne has recently appointed a new Austalian distributor. I have contacted the old distributor, who have told me that they are trying to get parts for my unit but are having difficulty getting a reply to their requests. I have also contacted the new distributor via e-mail & had no response at all. I then rang the new distributor & spoke to a very nice lady who told me that, as yet they have not appointed any service agents. I have also sent an e-mail to the contact page on the Velodyne web sight & again, no reply.

From reading previous posts your standard procedure is to simply replace an amplifier. Are you or Dave able to send me an amplifier direct & help me out of this less than ideal situation?:mad:

Hi,

I recently bought a sc-if/ic sub and have a couple of question regarding placement. The sub will be used in a dedicated room that's 20x28x9 ft but the theater part is 20x14x9.

1) Is it better to place the sub in the ceiling or the floor. The floor will be above the garage. The ceiling will be in an attic.
2) If I place it in the attic will I get a lot of sound leak (the attic connects to the house proper). My wife is a little sensitive to noise when she sleeps.
3) Normally I would place a sub in the corner does the same apply for the IW/IC?

Thanks

Hi,
1) The floor is your best choice.
3) Use a corner if possible.
The sub is small for your total area and the total area is what the sub will have to deal with. By putting it in the floor at a corner, you will maximize it's output capability.

hi,

I am thinking of adding a second sub to my system, the first being the SPL-1000 and heard that it is generally better to try and match subs, is this true? My watching habits are majority Blu-Ray/video games would the best current match be the SPL-1000R or is there something else which may be better if i dont match? Thanks!

Hi,
The SPL-1000R would be the best match. Since you don't mention room or area size, I recommend you go to: www.velodyne.com then 'which product' and then 'selection wizard' to see the proper recommendation. If you need more info, please call me tomorrow. I'm always happy to help.

Hi everybody,

I just bought the SPL-1000R, who can let me know the step for tunning the subwoofer?

1. Set the distance on AMP
2. Use the sound meter detect the level on 75 db
3. Set the Phase
4. Use the Auto EQ

Is it right ?

Thanks a lot

curt c

10-20-08, 02:37 PM

Hi,
I'm not sure what all you need. If you're in the U.S., give me a call.
1) Yes set the distance in your receiver.
2) Normally the speakers would be set to 75db and the sub to about 80db.
3) Correct phase is the loudest position or most often '0'.
4) Do auto-eq on the subwoofer first.
If you're looking for sequence, I would use the following order of the above.
4-1-2-3

As I have said before the SPL's are one of my all time favorite subwoofers. The last version (SPL-R) with DSP and auto-eq are with the exception of the DD series, the best small subwoofers available. The new Optimum series will replace the SPL-R series. The Optimum's should be shipping soon.

I have an HGS-18 that was purchased in April of 2000 which could be described on the exterior and the driver as still in showroom condition. Except for my 28-year old turntable (and me and my wife) it is the oldest piece of "equipment" in my HT.

I have always experienced a little what I think is servo "hum" that you can hear from maybe 5-feet away, especially when the unit first "activates".

However, now I getting a little more of the hum on a regular basis, plus now when you first turn the unit on with the main power switch in the back it hums very loudly at first and the hum slowly dies away for about a 2-minute period. (It is about the only sound in the HT that makes my cat run and hide!) After that is is business as usual.

Suggestions? Should I worry about the problem, or if it does not bother me should I just keep on using it as it currently functions.

The HGS-18 is fed a single balanced interconnect from my preamp subwoofer outlet and is set in the bypass mode. Both the sub and the preamp are plugged into the same circuit (although I don't think the hum is a ground loop as I do not hear it in any other speakers).

Thank you,
Mike

Hi,
It sounds like you're hearing the analog servo 'rushing' sound which is normally only audible a couple of feet away. If it doesn't bother you, I would continue to use the subwoofer. The other option is to return the amplifier for repair and update. If you wish to check that out please contact Velodyne service at: (408) 465-2800, ext 2848 or service @velodyne.
Thanks,
Curt (928) 858-4430 or curt@velodyne.com

I understand the "normal" sound that I hear from about 5-feet away in a quiet room. The noise I am more concerned about is the loud hum that the unit makes when the power switch is initially activated. Is that also a servo noise? Think of the initial level of the noise as a loud dialtone on a speakerphone.

Thank you,

Mike

Curt,
Are the new DEQ-R subwoofers better than the SPL-R subwoofers? In each respective size? If yes, how?

curt c

10-22-08, 08:13 PM

Hi,
Well it's an apples/oranges situation and it depends on what you mean by better.
The DEQ-R's are a bass reflex design, which also falls in the 'bang for the buck' category. In a bass reflex design, the back wave of the woofer is utilized via a port or slot to reinforce the front wave of the subwoofer in the lower frequencies. This is an efficient design which has more output than a sealed box.
The SPL is a small sealed box subwoofer. In order to play loud a high-tech driver with a long throw and a very high powered amplifier must be utilized. In a sealed box design you give up some output for a little more accuracy and depth.
There are proponents of both designs. If a limited budget is the primary factor and the room is large then a bass reflex unit is usually the best way to go. If the room is smaller and size of the the subwoofer is important, the SPL is a great choice.
The main criteria is the proper size subwoofer for the room or area. We have recommendations at: www.velodyne.com, then 'which product' and then 'selection wizard'.
For the same woofer size, the DEQ-R will play louder than the SPL. BTW, the new DEQ-R series is the least expensive subwoofer series available with a very effective multiband auto-eq.
If all of this is unclear, or you'd like help in your selection, please give me a call tomorrow. BTW, I enjoy phone calls and we can accomplish a lot in a short time.

Hello,

I have a V-1012-B (built in 1991) with a 12" floor-firing passive radiator that needs replacing due to separation of the cone and rubber surround across approximately 6 radial inches. It is my understanding that the original passive has been long out of production, and that a potential substitute (different mount pattern) is no longer a stocked item at Velodyne. Any suggestions? This powered subwoofer has served me well and is otherwise in perfect condition, so I would like to repair. I've tried delicately re-gluing the rubber surround to the cone with rubber cement, but this has not held long. I'm wary of replacing with a third party radiator, as I'm unsure of the proper weighting, etc. I noticed that the currently installed radiator uses an internal elastic band secured between the radiator and the cabinet ceiling to provide appropriate resistance. Any help is appreciated. Thanks!
Seems like a common problem as I have seen a few other comments regarding this vintage sub.
Thanks!

Curt,
Velodyne has a well-earned reputation for building some of the best subwoofers in the world, but in the last few years JL Audio has been able to build Fathom subwoofers that are highly competitive with the Velodyne Digital Drive series subs. In just a few years JL Audio has earned the respect of reviewers and forum members and are now considered by some to build subwoofers that outperform the Velodyne Digital Drive series. I believe the only Velodyne subwoofers left for Velodyne to update now are the Digital Drive series, and I hope Velodyne does a substantial upgrade with new technology, or improved drivers with more excursion, or bigger amps to gain more bass output. For the last couple of years, the JL Audio Fathom subwoofers seem to have taken the lead as the media darlings. As the home subwoofer pioneers, it would be great to see Velodyne remain at the forefront of subwoofer technology. Any comments or insight into possible future advances for the Digital Drive series that we might see soon?

theranman

10-26-08, 11:45 AM

Peter, you are so on the money with your observations. Personally, I think that Velodyne should have updated the their FLAGSHIP DD series a couple of years ago. Ya can't sit on your laurels any more in the sub business. If Velodyne can offer "significantly" more performance from the same size box as my DD-12, I might be tempted to upgrade. Maybe buy JL's driver. :)

curt c

10-26-08, 01:09 PM

Hi,
Of course Velodyne will always be at the front of subwoofer technology and we are looking at many possible new innovations for the next series. Velodyne has always stood for subwoofer accuracy and will continue to do so. With our servo technology we will guarantee the lowest distortion. How many other companies even address the issue? When it comes to bass management, no one else is even close. Others offer a single eq band to address the worst peak. Velodyne, in the DD series offers complete digital bass management with eight bands of eq, totally adjustable as to frequency, to address all the peaks. Bass management, to correct for room problems, is without doubt the most important single issue in a reference subwoofer. Some competitors don't even offer a remote control in their high end subwoofers, so fine tuning must be done at the sub, rather than the listening position. Frankly, I can't imagine owning a reference subwoofer without a remote control.
Just yesterday, a famous reviewer asked to purchase a DD for his reference system because as he stated, "Your bass management capabilitites leave all the other subwoofers way behind".
BTW, we constantly monitor our dealers and users regarding future developments and needs. I welcome suggestions for our next 'state of the art' offering. IMHO, the DD subwoofer's are still the reference and what other's use for comparison.
Thanks,
Curt (928) 858-4430 or curt@velodyne.com

A 'Y' splitter can be added to the end of a rca cable or some cables already have a splitter built in for subwoofer use. A 'Y' splitter or splitter cable into both input jacks of a subwoofer will provide more input voltage which is usually a good thing.
Thanks,
Curt (928) 858-4430 or curt@velodyne.com

I always had a 'Y' splitter cable that I used with my old subwoofer but hadn't used it yet with my Velodyne and it immediately made a huge difference. Thanks for reminding me. I had to find it but it was worth the search.

10-26-08, 06:47 PM

Curt,
Please view this as constructive criticism of the Digital Drive series. I view Velodyne products as wonderful products, but think there is room for improvement as competitors are starting to move ahead.

Digital Drive areas that don’t need improvement:
Bass management
Low distortion
Remote control

Digital Drive areas that do need improvement:
Maximum output: Several top subwoofers now outperform even the DD-18 in maximum bass output.

Digital Drive areas that can be compromised for overall improvement:
How much does very low distortion really impact overall sound and bass output? Many leading subwoofer manufactures do not use a servo design.
Enclosure size: DD-10 & DD12 should probably remain small to fill niche market, but DD-15 and DD-18 customers would likely accept larger enclosures for ultimate performance.

Potential solutions:
Increase amplifier power or better design
Increased driver excursion
Larger enclosures

curt c

10-26-08, 08:00 PM

Thanks for the input. I will tell you the one point that is against everything we hear, and you and I may be the exceptions, everyone wants smaller enclosures. In the big picture there isn't much demand for large subwoofers. So the challenge for subwoofer companies is get more output from smaller subwoofers. BTW, you can only get so many watts from a 15 amp circuit and we're more or less at that limit, and Class D amps are well over 90% efficient. And keep in mind, as to subwoofer size, wives usually rule!!
Thanks again,
Curt (928) 858-4430

theranman

10-26-08, 08:12 PM

So do condo dwellers! :)

If one wants THE most output, and is willing to sacrifice a wee bit of distortion at the very bottom, there are TONS of alternatives that use either cylinders or larger ported enclosures.
Personally, I like the aesthetic of the small subwoofer in my living room. If I lived in a house, it'd be a totally different story....as long as the big box can be somewhat kept out of view.

Curt: "See what I mean?"

10-26-08, 08:18 PM

Never mind wives, for some of us that have rooms where the subwoofer is prominently visible, I for one wouldn't want a sub that takes up as much room as a refrigerator, or looks like an industrial crate. I consider myself a basshead, but I just prefer to balance my bass with a "reasonably sized" box. For example, I was all set to buy a SVS Ultra Sub , but after I realized how deep and big it looked in my room (cardboard cutout), I nixed that idea. The whole point you bring up curtc about how the market is driving product direction toward smaller box subs seems to be a point that many AVS'ers seem to forget. Let the ID companies address the demand for maximum output, big boxes and/or ugly finishes but Velodyne can thrive toward small, well finished, accurate subs that put out plenty of output for their small size. Now of course, I wouldn't mind if they did cost less than they do ;)

Curt,
I’m not a speaker designer, but I know that any design is nothing but a series of compromises, whether it’s cost, size, weight or features. I’m also not advocating increasing the size of all Digital Drive subwoofers. I think it’s just one alternative that could help solve the output problem, but obviously there are other ways to make output improvements.

People who want the best performing small sub Velodyne has to offer can still buy a DD-10 or DD-12. BUT, a guy who wants to purchase a DD-18 will not care if the new model is 4 or 5 inches bigger on each dimension, if it will outperform any other subwoofer in its price range in every category. It would be nice if a bigger amplifier or higher excursion driver could make the entire Digital Design series better, but the DD-18 is already big and no other subwoofer in the entire Velodyne line uses an 18” woofer, so it really won’t matter if a slightly larger enclosure is needed to make it a subwoofer that is the best at any price (excluding the 1812). Again, I’m not implying that the latest iteration of the DD-18 cannot be designed better without becoming bigger, but if growing slightly is required to be better, I’m just saying the typical DD-18 buyer will not care. Maybe improvements in amplifier design and woofer excursion alone would allow for acceptable improvement levels for the entire line.

Other manufactures like JL Audio and SVS are now producing subwoofers that measure well, have higher output and cost less than the best Digital Drive subwoofers. Velodyne simply cannot allow this to happen.

Hi Curt,
I had a question about a strange 'rattling' noise I heard from my DLS-5000R yesterday while watching Iron Man.

This rattling noise can be heard during very loud and deep bass tracks (Iron Man going supersonic and the Jericho explosion soon after).

I made sure nothing was touching the DLS's cabinet externally which could be rattling or making noise so am thinking this came from within the enclosure itself.

Any thoughts?

I've owned two DD-15's since 2004 and due to relocation of my gear to a larger 8,000 cu ft. room, I have just added a DD-18. I've owned and evaluated many other brands. The Velodyne Digital Drive series is still the state-of-the-art in 2008. These are terrific subwoofers and more importantly, backed by a company that consistently provides outstanding and personal service.

Velodyne has assisted me 3 different times with unusual issues and requests. One was loaning a master factory remote so I could post programming codes for the URC MX-3000 remote control on www.remotecentral.com. After over 2 years of blissful use, Velodyne sorted out a glitch in the boards of my early production DD-15's that for some reason did not "update" when the 2.2 software was released. Bruce Hall personally responded and managed the problem. Both of my internal boards were sent back to the factory, the updated software loaded and the boards updated with newer components AFTER my 2 year warranty date had expired!

Velodyne has always continued to improve its subwoofer line. Undoubtedly, they are working on an update or successor to their top of the line DD series if for no other reason than to maintain a place in "top of mind" in the audio press and numerous audio enthusiast web threads.

As a very happy user, suggested improvements I've posted here before or have seen others post include:

- Perhaps a small digital readout on the front of the subwoofer to display which of the 6 presets has been selected that can be toggled to also display volume changes.

- Perhaps that the upgrade cable input be changed to USB.

- That the software be updated to enable selection of the monitor screen from a range of colors instead of only blue to assist owners of multiple DD subwoofers.

I've been amazed at how fast Curt here responds to this thread. Velodyne's Dave Santos has always provided outstanding service. Bruce Hall leads a terrific company of innovation AND customer service. They deserve their success.

Hi guys I need help.
This question may be answered somewhere in this forum but it is to large to search for so here I go. I have a Velodyne VPS1200 sub hooked up to a Sony STR-DG910 receiver. I also have a Polk sub that came with my surround system. Here is my problem. Everything sounds great until I power off my receiver. When I do so I get a low rumble from both subs that remains constant and never goes away until I power back up my 910. I have posted this question in many forums and still haven't got an answer that worked. Please help!!

curt c

10-29-08, 12:02 PM

Hi,
Since both subs have the low rumble, it certainly appears the Sony receiver is at fault. Try turning the sony off with the main power switch or unplug it from the wall. When you turn it off with a remote, it goes into standby, not off. I would contact Sony or take the receiver to a local technician to verify the problem.

I need to fill a sealed 1800 cubic foot room with quality bass. Which sub would be your choice between a DD10 AND A SPL1200r. I do not think I can go wrong either way. I know the DD series is a step above the SPL series. But would the extra 2 inches in size of the SPL model negate any advantages of the DD sub? I have a a chance to pick up either one of these used. Both subs are priced competitively and are less than six months old. Any advice would be appreciated.

Hi all! I've owned my HGS-18 for several years now, so I'm sure it's not within warranty. Anyhow, recently it began making a loud knock during intense peaks. I really love the unit, and can't afford to replace it at the moment. Are there any repair/upgrade options available to me? Thanks in advance!

Hi,
The subwoofer software will only be correct for one model so if possible make room for another SC-15. If you must go smaller choose the SC-12. The auto-eq will work correctly for both either way.

Curt don't get what you mean about it only being correct for one model. Do you mean it only takes in account one sub or that they must be the same size?

Hi,
With the SC-1250 amp, you select the speaker you're using, such as SC-15. You only have one selection. So if you are using two different subs like a SC-15 and a SC-12, you would select either SC-15 or SC-12 in the amp so it would not be exactly correct for one of them. This selection in the amp adds the proper low frequency boost and subsonic filter for the particular sub you selected, but not for two different ones. Also, the SC-15 would be more efficient (play louder) than the SC-12 so balancing the two could be an issue. That's why it's designed to use two of the same model subs. This software has nothing to do with the auto-eq which is room related. If this isn't clear, call me tomorrow.

I suspect there isn't, but is there a way to increase the sensitivity of the DD-18 in auto mode?

When I'm playing films at less than reference levels I'm often distracted by the click of the sub shutting off when it's been a long time since there's been LFE activity and by its missing the first partial second of an explosion or something when it turns back on.

I suspect I may need to run a trigger cable to the DD-18 from my Lexicon MC-8 instead; the manual says 12v must be present across pins 7 and 9 of the RS-232 out jack. I assume that would be the second from the left and rightmost holes of the bottom row when looking at the jack?

I have an F-1200R that was purchased in the 90's that has started tripping the overload circuit on loud passages. I had the same problem a couple years after I bought the unit and sent the complete sub in for repair. It has worked good until a year or so when this problem started but it was not too frequent. I just upgraded to a Denon 789 and have really noticed the problem more frequently. I ran the Audyssey setup, correctly I think. The sub vol control was set at about the 10oclock pos. and the db on the sub in the receiver was +2. Watching Hulk last night it was tripping on almost every loud passage.

I have created a service request on the Velodyne web site but have not heard back..

Just curious if there is anything I can do short of sending the sub back in..

Thanks

Hi,
Frankly this sub just can't deal with heavy, loud, home theater material except in a very small shut-off room. It is going into thermal shut down to protect itself. It was designed primarily for audio (2 channel) in a small room. If you have a very small room with no permanent openings you might get by with using a 'Y' splitter into both inputs of the sub, raise the Denon (sub volume) to about +6 and back off on the sub to 9 o'clock.

Hi,
There is no way to adjust the input sensitivity on the DD.
Raise the volume for the subwoofer channel in your receiver to well above half way and use a 'Y' splitter into both subwoofer input jacks. Then back off on the DD volume to compensate. Hopefully this will take care of the issue.

I'll try that, though I don't have a receiver, it's a Lexicon MC-8 processor and I already am feeding both sub input jacks.

If that doesn't work, is the assumption on the pinout of the RS-232 out jack for the trigger input correct?
