My question to you is what have you actually listened to so far, and how much do you like those Klipsch speakers. The worst thing you can do is to buy speakers without knowing what type of sound you're looking for or what's out there, and just relying on reviews or second hand opinions to make your decision for you. The only way you can answer this question is to go out and do your own evaluations. Speakers have the biggest variability of any audio component, and opinions on speakers are all over the map.

The Klipsch RF series has got plenty of fans on this board, and you have some Axiom backers as well. I've not heard the Axioms, so I can't comment. The Klipsch RF series I have heard before and while I like a lot about them, they do have their flaws. Then again, every speaker in this price range will have some audible faults. It's up to you which ones you're willing to live with, and which ones are automatic disqualifiers.
