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..

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:
