I have enjoyed having the QS series as my backs. They probably don't add a great deal to the overall movie experience for 7.1 , but they don't take anything away. I like to play music in the 7-Stereo mode and they really are nice to have under those playing ocnditions. The size of the room might be something to think about. I know I have a lot of space in the "back area" where the dog hangs out, so I like having the extra sound back there when playing music. Dog seems to appreciate having those back there with him too! He's mostly a soft-clasical guy in the day time when at home alone.
