Hi Bryan and welcome to you as well. Here's a link to the Audyssey thread where an expert is available for questions, but see below for what I (think I) know about Audyssey setup from my experience:http://www.avsforum.com/avs-vb/showthread.php?t=795421
My Onkyo 606 only has Audyssey 2EQ, which doesn't affect the sub, but I used REW and set BFD filters and measurements with only the sub playing and without the Audyssey EQ engaged. Maybe someone with MultEQ (or other advanced Audyssey EQ) could chime in with what to do with the sub in their situation.
Here was my final process (as always, anyone should feel free to chime in and correct any errors and I will update this post):
1. Connect the BFD in the chain, put it into pass-through mode and run Audyessey setup to get the sub level-matched to the system. If the sub was not at 0dB in the receiver setup, I adjusted the volume on the sub and ran Audyssey again. The 0dB setting seems to provide an adequate level to BFD as well as to "wake-up" the sub out of stand-by mode. While I'm sure that a few dB in either direction would be OK, this is what works for me.
2. Set crossover to desired setting. 80Hz recommended. You can adjust the Audysey-determined crossover up (i.e. change Full band/40 Hz/60Hz to 80 Hz) but not down (i.e. change 100Hz, 120Hz, etc. to 80Hz) as you will likely have missing frequencies in your sound.
3. Put receiver into "stereo" mode, turn off Audyssey EQ, disconnect the fronts, and run measurements in REW.
4. Create the filters in REW, upload to the BFD and engage EQ.
5. Measure the response and adjust filters as necessary.
6. Rerun Audyssey with the sub and BFD engaged. Readjust crossover to desired setting (80Hz).
After running with Audyssey EQ engaged for about 4 months, I wound up disengaging the Audyssey EQ and saw how it was muffling my speakers. In parallel, I also reduced the toe-in of my Polk Monitor 50 fronts so they were intersecting 6ft. behind the main seating position, instead of directly at it. (I probably should run Audyssey again just to see the effect.)
I don't miss the DynamicEQ and am enjoying the flat sub response, although I can adjust the Subwoofer output if I so desired. Of course, I'll likely dig back into REW and experiment with some house curves just for fun, (but will see what Larry comes up with first
