I need some help with setting the position of my Rear speakers. My Living Room is 23'Lx15'W and the back left side opens to the kitchen. The couch sits in the middle of the living room so it is about 11.5' from the entertainment center. Not having a side wall in the back left corner of the room I am forced to place my surrounds on the back wall which is another 11.5' from the couch. I cannot move the couch back as we have alot of teenage kids come over and some will watch a movie while other play games in the back area. My big question is how should I place the rear speakers. I read the article at dolby.com and they say to place the speakers on the back wall and point them at each other. Should I still do this when they are so far back? I did have them angled in at the couch, basically putting whoever was sitting in the middle of the couch directly in the center of the X that was formed by all four speakers. While this sounded pretty good it also was evident when something was coming from the back speakers. It never really got the "envelope" effect. Also any adjustments I should make on my reciever to help compensate for the distance?
