I had a buzzing in my M2's when i got them years ago and axiom sent out a new driver for the Mids. While i was waiting for it to arrive i decided to look into it and i found that the tinnsel lead on the back of the driver was rubbing the cone of the driver ,problem solved.

DOG is GOD spelled backwards.
What others think of me is none of my business.
