I have the Klipsch VF-36, which is in the same product line, but with some differences. The RF-35 has two 8" woofers and the RF-36 has three 6.5" woofers, believe the tweeter horn is the same size on both. I have used them front mains on AVR's with the stated 100/ 130 wpc statistics, on both receivers the speakers sounded great. They have good bass if you run them full range, but I run subwoofers so set my crossover at 80Hz.
Klipsch doesn't take a lot of power to drive (at least from what I've experienced and read about) so your receiver should be fine. I'm currently using mine as side surround speakers, maybe not the perfect solution but I wanted to use them somewhere in the system.
Personal opinion here only... good deal.
