Just a few suggestions, perhaps you should tell others what you plan on using for mains, rears, sub, and electronics, also room size and listening preferences.
IMO it is imperative to voice match front and center speakers for a more seemless blend of the front soundstage. Rears are also important, but room acoustics usually nullifies the possibility of accurately voice matching.
As for the Klipsch speakers you mentioned, I have personally demoed the RF series at a friends home. I was surprisingly impressed with them. They didn't sound as bright or "horn-like" as I would have thought. Viewing movies in his home on his Yamaha RXV-3000 and Klipsch speaker system was quite enjoyable, as was listening to music. A very nice budget system IMO.</font>
