Well unfortunately I have not heard the Axiom, but I am running a very similar Klipsch setup with and SVS sub and I must say that for movies they are amazing. For music there are better, but as far as movies go... comparing them against PSB, Paradigm, B&W I do prefer the Klipsch.
I dont think you would be dissapointed with them at all. Great sub with them makes all the difference for a nice smooth response.
My 2 cents.
