So, does anyone have any suggestions or experiences with either?
Though I agree with the other comments about auditioning them, I actually do have experience with both.
I've owned the Polk RT600i and the RT800i (along with the 350 and 450 subs) as well as the Klipsch RF5's, RB35s and RB81s.
I can't speak for the more current models, but based on my experience with what I've used, the "sound" of the Polks and Klipsch are two extremes. In my listening room, which is heavily carpeted, has drapes, bookcases and lots of furniture, the Polks sounded "reserved" for want of a better word. The Klipsch, by contrast, have a very extended high end which, in that environment, actually wind up producing a fairly well balanced sound.
However, in a room with bare floors, lots of reflective surfaces (windows, etc), little furniture....the high end of the Klipsch may be a little overwhelming. Some people just downright don't like the sound of compression drivers. I will add, though, that the newer Klipsch use a different driver (as represented in the RB81s I have) that has tamed the high end slightly. Some people feel this is an improvement.
That is why you are getting non-specific answers to your question. It is not possible for any of us to know what you would consider acceptable sound. If possible, don't limit yourself to just those two brands. For example, I also have a pair of B&W CM7s, which produce a whole different sound.
Both Klipsch and Polk are well constructed and are fairly efficient, though the Klipsch are more sensitive by far.
