Actually, I just had the same experience with my new Axioms. After I got everything hooked up and balanced, I was listening to Steve Wilson's new blu-ray music disc "Grace For Drowning" and when some solo piano started to play, there was a distinct fuzzy sound, which I soon determined to be the lower woofer in one of my M22s. Once I made sure it was the speaker and not somewhere else in the chain, I called Axiom and the nice automated system named "Brent" sent me out a new replacement woofer, no problems, no fuss. Right now I'm listening to a crippled M22, which is kind of sad, but still sounds decent.
Seeing this thread kind of makes me wonder just how often this happens, though...
