Jason is right, but in your case with the couch against the back wall, that will work WITH you if you mount the surround speakers on the back wall. I don't really like book shelf speakers on stands in this case, just because they take up so much room. This doesn't look like a dedicated home theater room, it looks more like a normal living room in hopes of making it sound better. I'm all for just mounting them flat on the back wall. If your receiver has a set-up mic, that'll help with any miss-placement issues.
