Done,Thanks.

BTW,i got it all setup and have a few quick questions.
I have the following setup..
Klipsch RF 7 Klipsch RC 7 Klipsch RB 5 Denon AVR 3808(pre) Emotiva XPA 3.Room ~ 2400sq.ft

I ran Audyssey and it set the sub @ 0db.Set the plate as instructed by Rythmik for AVR use.

Recommended plate amplifier settings
(from top to bottom, left to right)
1. Input: LFE (higher bandwidth) or LINE-IN
2. PEQ: OFF
3. Gain: 0db
4. Bandwidth: middle position
5. Frequency: middle position (40 Hz)
6. Delay/phase: 0
7. Crossover: max
8. Volume: middle position (12 o’clock)
9. LOWPASS filter: AVR/12
10. Rumble filter: OFF/1 for one port
configuration and ON/2 for 2-port
configuration
11. Extension filter: 14 Hz high damping for
articulate sound and 14 Hz low damping
for full bodied HT sound.


Ran a few demo scenes and it seemed a bit weak.Raised level to +3db while leaving the sub volume knob @ the 12o'clock position and it came to life.Does this affect Audyssey or is that simply the correct solution..Thanks.

You are doing right. Use the 3db setting for a couple of days and then you can revisit it and see if you want to scale back or keep it that way.

Brian,
Any issues using the Line-In connection on my E15 versus the LFE input considering Im using the line-ins on my D-15 as well(which does not even offer LFE-ins)?I have no desire to utlize any output of the sub beyond 90hz or so.

I do have my preamps low pass at around 85-90hz as well.

I was answering the part of his question concerning whether or not LFE or LFE + MAIN only applied when speakers are set to LARGE, and that is yes. Since most of us with subs have our speakers set to SMALL, these settings do not apply.

Brandon, yes, you can. That is the best way to make sure the two have similar phase characteristics.

Brian,

I sent you a PM.

Can't wait for Friday to pickup my LV12R from UPS. Kind of afraid it will overpower my energy take speakers but if that happens I guess I will just have to upgrade to some towers. smile.gif

Thanks Brian! I figured so, but thought I would double check. Thanks for the email response the other day as well! That scenario is what I hoped would work and it did.

Loving the Duals:)

My FV15HP finally got delivered (must of been the last box on the truck). Wife said UPS driver wouldn't take it into the house entrance eek.gif, so it is in my garage right now. When I get home I will unpack and acclimate it. Tomorrow night I will fire it up. biggrin.gif

Edit: It is so impressive looking. Tomorrow can't come soon enough.

The UPS man brought mine into the house and put it into the position that I wanted it for unpacking.

After a couple days of having the LV12R in and only listening to music, I have to say it impresses me more and more. It keeps up with Arch Enemy, doesn't stumble on Aphex Twin, integrates with the speakers perfectly on Massive Attack, and even works with Dead Can Dance (something that I haven't heard properly since my last set of planar magnetic headphones). It's taken everything I've thrown at it and laughed.

It also reinforced the fact that proper placement and setup is very important; the first listen I had with bad placement and Audyssey settings not right had me wondering if there was even a subwoofer in the room. Tweaked placement and played with Audyssey for a while and I can only imagine what some of the "big boy" subs like the FV15HP or FV25 sound like, given how impressive the LV12R is.

Just out of curiosity, what placement of the LV12R ended up working for you and what settings and input did you end up going with on the actual sub? I have played around a little with mine but I need to tweak a bit more.

Thanks for sharing your experience; I really enjoy hearing other customer's experiences. Glad to hear the LV12R is maintaining the high sound quality + performance of the other Rythmiks in the line up. Totally agree that placement and configuration have a big impact on proper integration.

I can confirm dual FV15HPs are a lot of fun. Prolly overkill for mostly music, but sound fantastic on that too.

I have the sub about 18" from a wall, right midway between the side walls - very far from proper "final" placement, but I'm doing a complete renovation and don't have a huge amount of space to spare at the moment. The sub volume is set to 12 o'clock, sub crossover is set to max on the panel, extension/damping is set to high with a 24dB/octave rolloff. Audyssey set the trim to a flat +0dB on the first go, 120Hz in Audyssey, and I've got Dyanamic EQ set on with a +0dB reference level setting. Output's coming from the subwoofer 1 preout on the receiver, to a y-splitter into the L/R inputs on the sub.

Thanks very much. Not so far off from what I'm testing but only using the L input (I'm still experimenting with the cutoff freq. between 40-120hz with my larger floor standing Vandersteens which go down to around 60hz).

Interesting that you are using a Y splitter to feed into the L/R inputs. I'm wondering what the possible benefit might be versus just using either the L or R input separately? Wouldn't the single subwoofer preout be combining the L and R low frequency channels anyway? Above 80hz, as you are using, I would suspect there might be some directional cues so placing the sub between the speakers seems very logical at 120hz crossover.

Any reason you are not going straight from the sub pre-out to the LFE input on the sub, but rather going to the RCA inputs with a Y-adapter? You've obviously chosen to do bass management on the receiver, seeing that you've set your crossover control on the sub to max (120Hz). I have my LV12R coming in tomorrow, and tomorrow can't come soon enough smile.gif

I had a splitter laying around so I figured I'd try the line-level vs the LFE input to start with. I'll probably switch between the two once I get everything put in place after the room renovation and see if I can notice a difference.

There probably really isn't any reason to use the y-splitter; I had one, so I tossed it on there just for fun. I may wind up bumping the subwoofer crossover on the receiver down a bit; I need to try some music with just the subwoofer hooked up and see what's going on at 120Hz and 100Hz. Since the speakers are set to 80Hz I like to have some territory in between the sub's LPF and the speakers' HPF to allow things to blend, but I definitely need to tweak it some. I haven't noticed any "subwoofer standout" where it becomes obvious the subwoofer is at a specific place in the room playing specific notes, though.

Using a Y and running L/R inputs in parallel boosts the sub's gain. No higher final output, but if you have an AVR with low output using a Y can help get the AVR's trim higher.

But in real life, I have a pair of 340SE, not because I don't want Magico, but because I have to make sure the sub sounds good even with mid-priced bargain speakers. The imaging capability of 340SE is very good. I ran Chesky test CD for the soundstage map, it is very big and precise. One of the tracks is a band chanting and playing around the mic, I can just hear them circling my 340SE (from the right of the right speakers, goes behind the speakers and go to the left of the left speakers, and then to the front of the speakers, and continue to circle). There is another one testing the height of sound image by running a shaker from the bottom of the floor, up to the mic and then continue to move up by the announcer (with his hand of course). Most speakers do not have problem for the first half. But the second half is more challenging: able to clearly hear the shaker is reaching the top.
Brian, you've got to hear your subs with Gallo Reference Strada 2 speakers. You need 2 subs because they like to be crossed over at 120Hz, but these speakers and your subs go together like Run DMC. Ascend 340s aren't quite fast enough for the hi damping setting; even if you plug the ports they blend best with mid damping/20Hz. I had to get the fastest speakers within my means to keep up with the high damping setting.

Some thoughts:
1. Does the servo have as much control over 100Hz as it does below? The midbass sounds a bit softer than the lower frequencies (it has sort of a mild drone): Could it just be because the sub is on the floor? Would a stronger motor help the cone track faster in the upper frequencies?
2. I wouldn't mind having a damping knob, with Q=0.3 as the lowest setting, for closer integration.
3. Could the midbass be tightened by altering the damping of the upper frequencies independently of the lower frequencies: Something like a 'Drive' control? (Enhanced square wave tracking) I know nothing negates inertia, but can we better mitigate its effects?

I had to help my UPS driver up a short flight of stairs with my F15.rolleyes.gif More recently, I had to send my 65 pound AV receiver in for repairs and an attractive female UPS driver came to pick it up. I dragged it across the floor to her and she grabbed it and whisked it away like it was made of styrofoam!eek.gif I have a long walkway but I could swear I heard the truck's engine start before I closed the door! Maybe she was wearing a weight belt under her uniform.confused.gif

I'm also interested in getting the LV12R. Would love to hear some thoughts on how it handles movie soundtracks. How "low" does it go...biggrin.gif

Thanks, Jon

I'm going to move some things around tonight so I can get the speakers properly located with the tv, and I'll give some Battlestar Galactica a shot tomorrow evening.

I've got Master & Commander, too, and that seems to be referenced as a bass-worthy movie...formulating some ideas here.

I have that movie and Cloverfield ready to go. Thinking I will give it a solid week of moderate levels before I try to push it at all.

I am going from some junk 8" 50 watt Sony that I have owned for 10 years to the LV12R. Can't wait till tomorrow either.

On the Phase control, (i use a 2 channel Receiver) if your speakers front and sub is on the same plane, the phase control should be either 0 or 180 right ?

As long as the subs are equidistant from the main listening position. A continuous phase control is the best option so if the subs are not equidistant (sound arriving at the same time), using a room analyzer program, one can better dial the phase control in.

From what I understand, if you use LFE out from receiver, it contain the .1 channel from 120Hz and below, so change the LFE channel to 100Hz might not be a good idea.

Just curious what makes the FV15HP 110lbs? I am asking because the PSA XS30 which is being compared to the FV15HP quite a bit here lately also weights about the same as the FV15HP. The XS30 has two 15" drivers v.s one 15" FV15hp.

Finally fired up my warmed up sub - it is an awesome performer in my room. It seems everything has come alive. So glad I went with Rythmik.
