Personally I think that the "takeover" of the living room by TVs and home theater has been one of the biggest "mistakes" in modern home design - they should be relegated to the basement or some other locale.
This is actually what I did in our previous home. Installed round Monoprice brand in-wall speakers, and hid the AV equipment in the next room, one wall away. It sounded--not too bad.
(It's partially a joke, but partially real - out of sight, out of mind!)
