What sub or subs are you going to be using?
If you're planning on running one or two really good subs you might want to think about the SVS bookshelf models instead if going for SVS.
For Klipsch there is no bookshelf model that has the same horn as the RF 7 so you'd have to get the tower.
IMO the RF7s will be a little more dynamic, most likely brighter and more efficient. The SVS Ultras will have more low end bass, which if you're running subs won't matter.
I like the klipsch sound. Have not heard the Ultras. They do get pretty good reviews.
I would think the SVS bookshelf model and matching center and surrounds would fit better in your room.
