OK, just trying to wrap my head around it.

When just the integrated is playing there will be no LFE so that makes sense.

But when the AVR is using LFE then the subs will ignore the line level inputs from the integrated amp which is being used because of HT Bypass? Or the line level inputs do not matter for some other reason?

If you have an Integrated amp with a well designed HT Bypass then no signal should come out of the Integrated when HT Bypass is active. That;s definitely something you have to check with the manufacture of your Integrated.

Yeah, I'll need to check that. The manual doesn't say. I believe in previous testing that the signal does pass through the pre outs in bypass mode. I took advantage of that when I had a Cary Audio which turned subs off when the mains were set to Full.

mini-XRL male cable for compact amp

Does anyone know where to get a premade cable that will plug into the female mini-XLR input of the Rythmik compact amplifier series?

An standard XLR female to male mini-XLR adapter cable would be ideal.

Thanks

My old Krell passes signals in bypass mode out the preamplifier jacks. So I'm going to have to come up with another plan

Here is my latest compression sweep for the subs only.. There is a dip/null around 80 hertz that goes away when I use the speakers.. I recently added a 4th FV15HP that I got at a decent price.

For the last sweep, I started at 20hertz since it was already compressed below that.

You can use this one: http://www.bhphotovideo.com/bnh/cont...=REG&A=details

Or buy the 3 Pin Mini XLR Male Connector and a standard XLR female and build your own cable.

4 FVs - super nice. Are they each in a corner of your room? Have updated pix? Can you scale your horizontal to 8-200hz? I assume each higher graph was increased by 5db?

No I have 2 in the front and 2 stacked in the back.. Yes the last graph was increased by 5 db.. I recaptured the graph with better scaling..


Compression sweeps with better scale:


Here is how I set them up for those interested:
Here are the front 2 and their sum:


Here are the back 2 and their sum:


Here is the front 2 , the back 2 and all 4:

Notice that the sum of the front 2 and the back 2 is less than the back 2 alone after 50 hertz..

I added a LPF for the front subs to cancel their output above 50 hertz.

Here is the back subs and the front subs with the LPF and their sum:


Looks better than when the fronts were active above 50hz. It seems to me that I can use the output of the front subs between 70 and 80 to help get rid of the 10 db dip since there doesn't seem to be a cancellation there.

Before and after eq




I haven't taken pictures yet but planning to take some soon.

@ahmedreda ,
Graphs look great!
How does it sound?

Did you also try a 4 corner layout, or was there not room for that?

Your room has really gone into the big leagues!

Thanks! They sound a lot better than they did with just 3. Now that the back nearfield subwoofers are contributing the majority of the sound they do have a lot more tactile feedback than before. While testing, I had to pause to make sure the crowsons were off at one point.

The front corners are occupied but I did try moving the back subs to the corners but the response was worse in the range I was trying to correct (60-80hz).

My next upgrade would be atmos and I am trying to decide if I want to buy one of the new year models with hdcp 2.2 and dts-x or get one of last years models for cheap since I am not planning on upgrading to 4k for the next 2-3 years at the least. I may wait to hear the reviews for dts-x before I make my decision.

Glad you decided to pick-up another FV after all. I decided to just hold onto my FV's since I couldn't really justify upgrading at the time to anything else. I'm waiting patiently to see what Brian has in store as the FV15HP's successor.

Receiver - Denon 4311CI
Speakers - Klipsch RF-82 II's, RC-62 II, RB-61 II's
Subs - Rythmik FV15HP's

I was in the same position and it made more sense to me to add one more sub. I now more headroom than I need for my listening levels ..

Did Brian give any hints about the FV successor?

If my memory serves me correct the last time I was at the shop he mentioned the possibility of adding 18" subs to the line up.

I think that would be a good move to compete with the rest of the ID sub manufacturers as almost all of them offer 18" subs.

Agreed. I'd be the first one to ask for a unit to review.

If you take yourself too seriously expect me to do the exact opposite

Ahmed, is the bass localized having 2 stacked in the back? What do you use for LPF? What do you use to Eq subs?

I bet it will be a great sub but what about the price and size?

I'm thinking ~$2000 shipped, but maybe Brian will chime in and shed some light.

I use a minidsp 2x4..
The bass is not localized as long as I keep the cross under 80hertz.. My MLP is 3-3.5 feet away from the subs.. I think if I had it closer, I would be able to tell it is coming from the sub.

I first use the minidsp to eq the basic response (basically just the LPF in this case) then I use dirac live on the minidsp ddrc-88a to eq after that.
