Hello, Basically my situation is this... I have a dedicated media room approx. 16 X 21', with two rows of 4 recliners (back row on a 6" riser). I use the Audyssey calibration on my Denon AVR3808 receiver, and the back row (especially the two end seats nearest the back corners) is getting overpowering low frequencies from the subs, while the front row is getting next to no bass response whatsoever. I have been struggling with this for a few months and I think I've tried just about everything (multiple subs, different locations, crossover frequencies, phase adjustments, etc.). I even tried stacking up some foam in the two back corners and I'm still not seeing any improvement. I think I'm at the point now where I want to have a professional come in and evaluate the room for acoustical panels and/or bass traps, since what I've read seems to point toward standing waves and null areas in the room causing the problem. Just would like to know if anyone has any recommendations either online or locally (Dallas area) and also what exactly I should be looking for. Thanks!
