I have a dedicated Klipsch reference 7.1 home theater. I use rf-7's for mains, rc-7 for the center and 4 rs-7's for the surround and the back surrounds. I used the rb-7's for surrounds for a while but I like the sound of the rs-7's better. I like to listen to my theater loud, I use ATI 250 watt per channel amps and I have no complaints. With rb-7's I could tell exactly where the sound was comming from. With the rs-7's it is more of a diffused sound. It gives me more of a 360 deg. sound field with no gaps when the sound pans from speaker to speaker. In a theater I like the sound of the rs-7 better for live concert dvd's and movies.
