Spoke with Brent at Axiom today and I believe he stated that the "dynamics" could be dramatically different. He specifically mentioned the cabinet size havind a lot to do with dynamics and the extra tweeter adding to detail. He felt the M22/sub is an excellent combo but (and I would like to make this statement precise but I will not doubt fail) (maybe I'll just leave it as "but" so that I don't misquote.)

Would be nice if anyone from Axiom ever visits any of my questions. I feel left out and I am very sensitive!
