Welcome to AH, Flossmore!
Can't see why anyone would grumble at the fact that you're a fan of the Klipsch Reference Series, they're solid performing speakers and some of better lines Klipsch offers.
While the KLF-C7 likely would work, I would think the RC-25 would be a better overall match for the RF-15s and RB-25s. Spec-wise, the KLF-C7 looks a bit more powerful, but the RC-25 isn't too far behind and would likely be a bit easier from a placement perspective being a smaller form factor... -TD
