When talking about separation of speakers, does this include the center channel also?? So if I had a 120" opening if I needed 6 ft between all three, that means I need 12 ft of space or does this measurement apply to the FL and FR. If I wanted to go with a M60 for the FL and FR can I integrate the VP150 with those two?? Is the VP 150 a match. the though is to have say 7ft between the FL and FR and the VP150 between the two.

I have read this also and am considering the options available. This is going to be a DIY AT fixed screen. Behind the screen I am going to paint the recessed area black. the cloth will most likely be SeymourAV (which has good reviews, even considering loss in brightness.
