The screen's bigger when you sit closer, and at 1080, you can sit pretty dang close!I think I'm only going to go with a 5.1 system. The room is real small. 12x11. I purchased 2-LSi9's, LSi7's & LSiC at the same time. I then found a deal on 2-LSi9's and purchased those too. So I'm going to use either 4-LSi9's or use the 2-LSi7's as rears.
No idea on a sub yet.
See it's a small room. Still have to purchase a couch. Seating will only be about 6' from screen.
