I know, I know, this topic is beaten to death, but I have a question too. I currently have my surrounds mounted to the ceiling (and in line with the listener) as the back wall is a sliding glass door and my couch is pushed up right against it. There is really no other option. Should they be tilted down toward the listener, directed forward or behind the listener. Sometimes I think I hear one louder than the other and vice versa when I'm adjusting their position.
