I'm a newbie building a home theater room and need some help. My room will be 11'x13'x8' with hardwood floor, no windows. All walls/ceiling are plasterboard. Planned viewing is in the 11' direction. I'd like to make the wall behind the TV a half-wall, about 4' high. Behind that is another room 10' deeper and 15' wide. The half-wall is only to help the rooms feel open. Will this screw up my 7.1 surround? I'm more concerned with sound than aesthetics and will enclose the room if needed. Would appreciate any help, thanks.
