I just recently got a house, a pair of SVS subs, and a BFD. So i'm tinkering trying to equalize the response in my room. First, here's my setup: Yamaha RX-V1 Dual SVS 16-46CS+ with Samson 1000 BFD DSP1124P Polk RT-800 (main) CS-350 (center) RT-55 (rear) All speakers are set to small. I'm using the bass test tones from Sonnie's site. These values are run at -40dB. When I calibrated with VE I set all the speakers around +/- 1dB and the subs at -18.5dB. For the tests I have my speakers turned off and effect off (stereo mode). And here's my results: I have two filters set 34.1Hz, BW 15, Gain -6 59Hz, BW 10, Gain -6 I'm pretty happy with my results so far, except for the nasty valleys at 20Hz and 71Hz. I have plenty of headroom. considering where my sub volume is set (-18.5 on the receiver, Samson on full) and I don't think I'm in danger of clipping. So should I give a little gain at 20Hz and 71Hz, or should I try to drop everything down to those points?
