The only Klipsch that I heard were the RF82 and RF62 and also the horns didn't bother me, I thought they lacked in the midrange area. I haven't heard the RF7s.
It looks like you are over analyzing everything. No matter how much you read, it will be no substitute for hearing the speakers. I know that it might be difficult in your case but as others have said, the M22s and even the M2s will be representative of the Axiom sound and as for Klipsch, you might be able to listen to them at the dealer. Good luck.
