i've been having an ongoing problem with a mid-bass standing wave at my listeniong position that i'm hoping one (or more) of you might be able to help me with: i've got def tech 2000tl's for my fronts (clr 3000 for the center channel), firing down the long axis of a rectangular room that's about 20w x 30l x 8h. the wall opposite to the speakers is actually floor-to-ceiling windows - an acoustic nightmare, i know. there's a particular mid-bass frequency that has to be about +6db or more that shows up every now and then in movies and music. it's particularly bad in "atlantis the lost empire". all the other bass frequencies are ok - astonishingly fast and clean - down past 20hz (my couch and chest go nuts, e.g. during the opening of gladiator and the pod race in episode 1, and when the train is about to crash in unbreakable, i can't hear anything, just feel my floor and chairs shaking shaking shaking). i've tried everything i can think of: toed in; not toed in; subs on; subs off; speakers set to small (with sub); speakers set to large (with and without sub); speakers inward, outward, side to side; subs firing outward; subs firing inward; socks in the ports; ports open. and every combination and permutation of these - and no matter what, the room resonance persisted. have i missed anything? i can't change the listening position, and i can't bring the speakers any further from the wall than about 1.5ft (that would put the left one smack in the middle of a doorway. incidentally, the gain was pretty bad on one cd i have, and ever since i hooked up both the full-range inputs AND lfe, and set the subwoofer to "on" and the mains to "large", it has vanished. but not in the movies. weird. (not only does the music no longer have any standing waves, but it sounds much cleaner all around, something i'm going to go out on a limb and attribute to the new RhinoCables i just got...) i know you guys are probably sick to death of dealing with questions like this, but i'm hoping you'l take one more kick at the can... any suggestions?
