The seating area occupies 12 by 14, if you make a rectangle between TV and seating. But the overall room is 20 by 15. There is empty space in the back not part of TV viewing area. So the listening area is really 12 by 14 in a 20 by 15 room. That's why I want rears, to take advantage of the couch being 7 to 8 feet from rear wall. My spacing looks pretty much like Dolby shows their 7.1 layout on their website. It is supposedly better to have the couch not on the back wall when possible. Does that clarify? I realize I was confusing before.
