Thanks,
wasn't quite sure .... I am going to be 6 - 8 ft away from the rear walls. Not quite sure if I am building it 19ft or 21 ft long yet. and either 13.5ft or 15.5 ft wide. Really going to depend if I go with the 60 plasma or 120" Front projection.

Currently ,I have three MK 750's across the front. I was wondering "if" I should go with 7 MK 750's or three up front and two in the rears and two QS8's for the sides. or if I should go with three MK up front and four qs8's.
I was back to my brothers tonight and he has direct for the rears and in music they were nice, but not for movies. They were 3 ft behind.
