Room Acoustics

Suggestions for this annoying problem appreciated.I get an annoying room resonance in the low mid bass that just excites the hell out of the room in spite of speaker placement, different amps, and corner treatments( 4 corners with ASC super 16's to the ceiling), curtains over sidewall windows etc. Speakers are Eidolons, room is 15wX22dX9h. Short shag carpet, speakers on apex couplers. Sound is 99% stunning with that occasional Dave Holland bass note that just won't quit. I think it's possibly the floor, pier and beam over a finished rec room in basement. I'm considering putting the Edolons on granite and maybe having someone professionally check the room acoustics. Is this related in any way to the downfiring port of the Eidolon?. Thoughts appreciated including any suggestions as to someone coming out to test the room. Thanx in advance.

What is your wall made out of. If it drywall on stud it usually acts like a drum near the frequency you are describing.
If you do have that kind of drywall simply thump the wall in various areas and listen to the thud. Compare it to the pitch of the blooming artifact from the speakers. That might be helpful.
This is similar to the floor artifact you are describing bu thas a pitch nearer to what you are describing

Mark,
I have a pair of eidolons and the ascents before them and I have found them difficult to position so they are at their best for bass extension. That is not quite what you are referring to but I have found peace of mine by using a sigtech for the same amount of money and significantly better WAF than the tube traps. Before you really consider getting rid of the speakers why not try a Tact or some other such system. Tact has a 3 week trial period with money back.
The only negative of the sigtech is that it ruined alot of my tinkering that I kind of enjoy doing. On the other hand I think I enjoy listening more now.
