Thanks for taking the time and your input. That sounds like it makes sense. I do not have any space between my couch and the rear wall. When I am watching a movie, I will pivit the speakers slightly towards the couch. It's funny, I don't want to lose the music quality by going with the RS25's but I rarely have my rears on when listening to music anyway. I just wonder how much an improvement they would be. I would hate to waste the money. The RB's are barely a year old.
