I use direct radiated (Monitor Audio Bronze - $300) and they're installed roughly 3 feet above and behind the last row of seats in the theater. They sound ok and do what they're suppose to do. Frankly, I've listened to allot of speakers and I've never had my socks blown off by a pair of surrounds; no matter what the cost. That said, other than playing SACD or DVD-A, I normally listen to 2-channel music.
