* Offical Velodyne Support Thread * - Page 12

Curt,
is there any reason why my DLS-4000 would be passing sound through when in standby?

My Yammie is in a bigger enclosure and is ported. When I said it filled the room I surely didn't mean it filled it with clean sound. Just muddied sound I guess. The HGS-10 sounded better that's for sure and it is in the clear enclosure (good conversation piece). For my room size and layout I don't think it gives me the best bang for my buck. Of course I have been listening to muddied bass for 2 years so what do I know.

Well, it seems you know enough to trust your ears, and that's a very good thing.

Hey Curt
Is Dave Santos still around (holidays ?)
Ive been waiting several weeks for some direction in getting my
F-180011 back up and running ( the amp wasn't the problem)-
Thanks

Hi,
We're back from CES. I forwarded your message to Dave, he will be in touch. Sorry for the inconvenience.

Curt or Bruce,

First I'd like to say how awesome this forum is. It's incredible to be able to ask detailed questions about your set-up and get advice from knowledgeable customer service reps. Compare that with other companies where you wait on hold forever and have to be transferred several times till you get someone who even understands your problem.

I don't even have a problem - my main reason for this post is to let you know how happy I am with my Velodyne Deco system. It fills my 12' x 24' home theater with much more clear sound and deep bass than I ever expected in this price range. And this is in my family room that has cathedral ceilings, an open stairwell down to the basement (door at bottom of stairs), and is also open to an 8' x 10' pantry above the stairwell.

I have the Deco speakers hooked up to a Kenwood VR-6070 6.1 (6x100 watt) channel receiver and use a Pioneer DV-563 DVD/DVD-audio/SACD player. Having 5 identical speakers sounds incredible with DVD-audio and SACD sources. I still can't turn the system up as much as I would like without my wife complaining about how loud it is (I know, get rid of the wife, but that's another issue). This Kenwood receiver gives you the choice of using the 6th amp for either a surround back speaker or a non-powered subwoofer. I'm currently running a dipole speaker from my old system as the back surround and running the Deco sub from the LFE jack. I'm considering getting another Deco Satellite for the back but I'm pretty happy with how it sounds now (and there aren't a lot of 6.1 channel sources yet).

Now two questions:

From reading this thread I assume that you would recommend a 15 or 18 inch sub for my room. I'm not looking to upgrade now but would replacing the Deco 8 sub with a DD-15 make sense as an upgrade path?

I have a decent non-powered 10sub from my old system that I'm not using. I could use it at the back of the room to provide extra bass in the surround channels (set the surrounds to large and run the rear Deco's thru this sub). Do you think this would help or just muddy the waters?

And one comment:

I think the fact that the Deco speakers are 4 Ohms are scaring off a lot of newbe buyers.
The manual for my Kenwood receiver says:

Speaker impedance
After confirming the speaker impedance indications printed on the rear panel of the receiver, connect speakers with matching impedance ratings. Using speakers with a rated impedance other than that indicated on the rear panel of the receiver could result in malfunctions or damage to the speakers or receiver. (The rear panel says connect 8 -16 ohm speakers.)

That's pretty scary even though Velodyne states Impedance: 4 ohm nominal (compatible with 4/6/8 ohm receivers and amplifiers).

Thanks,
Rock

Rock,
First of all, keep the wife.
We're very proud of the Deco system. It's the greatest bargain in the H/T arena period. I wish more people would check it out. We tested it with many entry level receivers and never had a failure. Entry level receivers often save money on the power supply so they advise using 8 ohm speakers (their disclaimer), which require less current to drive. The Deco's are usually in the 6-8 ohm range and should not present a problem. Some 4 ohm speakers dip well below that and could be an issue with these receivers.
The Deco satellites are available seperately if you decide you need one or two more.
You do have a large area for the subwoofer to cover. There are a couple of ways you could go. The HGS-15X servo sub would be a major improvement and of course the DD-15 would be the ultimate way to go.
Thanks for the feedback and enjoy.
Curt

Curt,

I very much agree that the Deco system is the greatest bargain in the H/T arena. I expect to enjoy this system for many years. I'll probably get one or two more Decos for the back and dream about a DD-15 in a few years.

If you could get more people to hear this system (and directly compare them to the B* company's) you would sell a lot of them.

If you could sell a "package" with any of the entry level receivers (so people would know they were compatible) you could seriously cut into the HT-in-a-box systems people are buying with their HD TV's.

Thanks for the reply
Rock

Which sub in the Velo line would be comparable to the sub in the Deco system?

Frank,
The SPL-800 is the most comparible.
Curt

Hello,
I just started my home theatre system with the purchase of the Velodyne Deco Speaker System. I was wondering what the best receiver was for this system?

Hi,
Within a given price point most receivers perform about the same. Look for features or cosmetics that appeal to you. Any of the major players will be a safe bet. One thing I would look for would be some flexibility in the bass management section. For optimum performance with the "DECO" system, I'd look for one that offered a crossover in the 110 to 130hz area. Most current receivers offer several crossover points. Enjoy the speakers, they're really special.
Curt

I couldn't find an email link on Velo's website, so I'm asking here.

Can a person use the features on the Digital Drive Subs to help dial-in other subs I own? ie Can I use the On Screen Display/mic setup through the Velo to achieve a flat response in conjuction with a different sub/eq without having any LFE or signal to the Velodyne?

Yes that would work. It would also enable you to select a good location for the other subwoofer. That sub would require, as you stated EQ capeability.
Curt

Just want to thank David Santo and Curt for excellent support .
David really helped me out in getting back up and running .
Everything worked out great and will continue to support and
recommend Velodyne products .
Thanks Guys

I thought I read "sub #1" would not need EQ ability if you added one of the new digital drive units.
I had planned to add a Digital 18" to pair with my HGS-18V2 and hoped the new one could EQ the room (with the adjustments available on the HGS-18).
True?...Not true?

Hi,
Yes, you could be playing sub #1 (non DD) and EQ with the new DD sub. That would be the normal way to do it. The previous question was a specific situation where he had EQ capability with the existing subwoofer and wanted to know if he could utilize the on screen display (of the newDD sub) in conjunction with that sub.
Hope this helps.
Curt

Hi Guys, I just went ahead and bought the DD-15 and then I realized that I don't know for sure if it is video shielded. Does anybody know if it is? Can't find the info at the Velodyne site.

Hi,
The DD-15 and DD-18 are video shielded, the DD-10 and 12 are not. Not enough room in the smaller cabinets to do it.
Curt

Good answer! Thanks Curt.

Thanks Curt.

I would like to know if the SPL-1200 Series II can accept spikes such as the Dayton 240-715 on www_partsexpress_com. I have a prewired location for a subwoofer that includes an electric outlet as well as a subwoofer cable outlet. The tops of the wall plates are about 16 1/8" above the carpet. I would like to try raise the 1200 up enough to fully cover the view of the outlets and I thought spikes might be a good way to do it.

Hi,
My guess is they will fit. The spikes I've tried all fit. The hole is 1/4" 20- thread count. Thanks for the question.
Curt

First I would like to say thank you for all the good info.

I am building a dedicated room 22x15x9. I am, currently using an HGS15 Should I try to find a used one for my second sub or if I go new what would match best with it?

Thank you in advance

Gary

Gary,
In a new sub, the DD-15 would be the ideal match and you would have the ability to EQ the room with the HGS-15 playing.
Curt

I'll echo the view that it is awsome to have this kind of access to the Co. Even good dealers usually can't answer all these kinds of questions with authority.

2 Questions:

1) Can you place the sub in a recessed cubby hole in the front wall behind the main channel speakers as long as the front of the sub is flush with the front of the wall. Was thinking about building it into the wall and then covering it with some sort of fabric so the sub does not take up floor space;

2) In a big room, what are the pro's cons of going 2 DD12 or DD15 vs. one DD18. If you use bruce's formula for SPL of 2 x pi x r x throw, for 2 DD12s you get 131.9 vs. 98.6 for a single DD18. Based on those numbers can you deduct that the 2 DD12s will generate 32% more output than the DD18? Also, what pros/cons (other than price) might there be to factor into the thinking.

Thanks!

Hi,

1) No problem, the closer to the floor, the better.

2) Here's the way I would equate this one. Lets' look at the size of the pistons involved, 9.7" for the DD-12 and 15.2" for the DD-18. Using (pi r**2) to get the area for each, we come up with 73.9" for the DD-12 and 181.4" for the DD-18. So if we add the two DD-12's that would give us 147.8", well short of the piston size of the DD-18. The throw (push) of the pistons would be constant in this example, so you can't double up on that figure. So two DD-12's would be closer to the output of a single DD-15 (126.7") than the DD-18.
In general, a second subwoofer of the same size and type, placed in a supportive position will add about 6db output.
The decision of two small subs vs one large one often has to do with placement space or attempting to get flatter frequency response at the listening position.
I hope this helps some.
Curt

jrz1, just bite the bullet and get the Velodyne 1812, then you will have the best of both worlds.

Curt,

That does help. I was incorrectly assuming that the model #s indicated the diameter of the cone and hence r was 1/2 the model number. With your correct figures, the decision is a bit easier. With respect to the mounting, I will likely sit the sub on the floor facing the listening area and placed in a small cubby hole carved out of the wall just larger than the sub itself. Thanks again.

Jim

Looking for some input from owners of the spl1000.... how do you like it? Is it good for listening to low-med volumes of music in a room 10x12?

Also, what is the primary difference with the II upgrade?
