I am putting together a dedicated Home Theater room, 5.1 system with wiring for future 7.1 I am wondering about where exactly I should be placing the rear speakers, and how far apart should the fronts be.

The room is about 18ft deep by 13ft wide. I am going with a front projector and 106" screen, about 92" wide + frame. Seating will be about 13 feet back, 2 rows, with the second row raised 8 inches stasium style.

I was thinking for the side dipoles, putting them about 6 feet off the floor on the side walls even with the gap between the rows. And for the fronts, placing them aside the screen about 11 feet apart, slightly toed in.

Does all this sound about right. Let me know if I left any info out. Thanks.
