Attached you will see an elevation drw'g showing, well the elevation and option one on proposed layout. I thought building an interior, free standing wall, would utilize the open space more efficiently with the ability provide better sound throughout the room and the ability to see the TV from many areas. I would can use a 7-1 (2) set up but no rears as shown. Option 2. Swing the whole setup to the left wall, same 7.1 (2) but no side surrounds and the abitity to use rear speakers. This limits viewing area and full room sound. It also leaves a lot of open area, and I'm not planning to fill it with new furniture. Wiring is not an issue in either option. Any and all opinions are greatly appreciated, as a decision must be made soon.
