Nut, as I quoted him, Dr. Toole explains why first order reflections should be promoted(not suppressed)by bare side walls in front of the speakers, but among the treatments he does suggest(p.507)is absorbing material on the center portion of the front wall behind the speakers Thanks John, that makes sense to me, but why the centre of the front wall? Isn't that normally where the display is located? In my case I plan on a front projection screen, so I won't be able to put panels there. I may be able to put some directly behind the front LCR speakers though, since they surround the screen. I wonder if putting treatments behind the M80's will suck up the bass coming out of the ports?

The panels would have to be placed so as to not obstruct the screen. Panels of the thickness involved(maybe 3-4")have no significant effect at bass frequencies.

I can see how the first reflection might help, but in my room the first reflection was so close to the original sound that it made it muddy. By delaying that 1st reflection some, it helped improve the imaging. I think getting 100% absorption of the 1st reflection would be overkill, but here we are talking about slowing only a portion of the entire reflection.
