Thanks for the responses. I wasn't sure if these would be too heavy for standard drywall anchors. Does anyone recall what size they used. Plastic or metal ones.
JohnK: These are being used as side surrounds in a 5.1 set-up. Unfortunantly side positioning or mounting of any kind is not an option in my room layout. Originally I was going to use a pair of direct firing bookshelf speakers on stands facing each other behind the couch but decided the QS4 design might work better. So you are saying that on the back wall at that height and spread out will still give me good surround effects?? And would this position work better than what I was originally going to do. Which was place them at both ends of the couch about 3' up.
