Hey Adam,

The QS8s are pretty flexible, just try to aim the fronts of them toward the listener (so that the tweeters and woofers aren't aimed direct). This makes the sound more difused and it works well for movies. I think Dan has a good suggestion in mounting them on the back wall. Then you could put them at about 5 or 5 1/2 feet off the floor, and a little closer together (I'd say about the same distance as the front M60's are apart).

Looks like you are getting some good help here (not surprised ).
