Thanks Sushi-

You've got me motivated. I'm headed home to do some radical revision of the speaker placement. Move them apart and further from the rear wall to start. Then closer to the rear wall......

An interesting twist on this discussion is that if placement is very critical (and let's hope it is - so that I can get these m2is to sound really pretty) this doesn't bode well for wall mounting your front speakers - which I was thinking of doing.

Any suggestions on my 1 through 7 post?
