My tweeter just lost sound on one of my M22's. When I first received my pair of speakers the tweeter on one of them was not functioning, I called axiom and they kindly sent me a new one.
However my new one just seemed to die the other day and is not producing sound at all anymore.

I am wondering if there is connections I should be checking in my speaker and if I do so would it void a warranty? Also how might this be happening to avoid it in the future?
