To answer Newbee's question, I get the flutter echo pretty much everywhere in the room. I did have my wife clap at the speakers while I sat in the listening chair- pretty much the same results as anywhere else.
I have a plush carpet with 1/2" pad througout, so no hardwood floor interactions.
I haven't been able to pinpoint the source. I have some 1" styrofoam sheets (4'x4') that I can hold up in various places to do a 'clapping' experiment. So far no smoking gun, although I used this technique in another room and was able to tame it almost completely. I guess my next move is to try climbing a ladder and blocking various spots up near the peak, or maybe the high corners . . .
