Cool. The 7.1 would be very cool. My problem is the room is actually huge (a lot of space between the back of the couch and the back wall), but they still placed the rear speaker hook-ups only 12' feet from the TV, which is where I have my couch. So the rear speakers would be directly above it, and not behind it.
Unfortunately, two story houses make it hard to add wire in the ceiling. I guess I could just use floor standing, or bookshelf, speakers behind me and not use the pre-wire in the ceiling.
Is there any documentation that you know of that recommends that the rear speakers should be at least a certain distance... such as "approximately 15 feet from the TV" or "at least 3 feet behind the couch" ? If I had that in writing, I could make the home builder move the speaker pre-wire.
