overwhelming bass/drone in some of my music, even at the smallest room setting, danny has suggested something that would drop it even lower, i hope it works! i can only manage 12.5" away from a acoustic panel, which sticks out 3.5" off the wall. so about 16" away from the wall if i removed the acoustic panel.
might be a room mode problem, will definitely play around with these for a while before i consider anything.
Instead of treating your room and *hoping* that you flatten out your in-room bass response, might I suggest trying the
DSPEaker Anti-Mode 2.0 Dual Core? I just started using one in my small room, and it's really working for me. I like it because, even after correction, I can add/subtract bass (and treble) from my room on the fly, depending on the music, listening level, mood, etc. I can even hit 'bypass' on the remote if I want my old 'boom-boom' back

. Plus- bonus! - it's a really good hi-res DAC and is super flexible with regard to where and how you want to use it in your system (analog, digital, DAC, preamp, etc.). Here's a before/after plot of my in-room response below 250 Hz (took 5 minutes to calibrate) to give you a sense of what it does (the dip at 80 Hz is a cancellation null that will probably require another sub to fill):

Pretty cool...
