For quite a while, and it was only audible on certain recordings, there was a light buzzing sound coming one side. I blamed almost everything and tighted loosened stuff all over the place. Then I thought it might be the QS-8... so I flipped side and then problem went away! Therefore, I thought it was the bracket that somehow was in a bad position and caused light vibration.

Until two weeks ago where it started to do it again... from the other side! Now the problem is that, at the time, I was not certain at all I had swapped the QS-8 (i was actually under the impression that I had just "re-set" the bracket). Well... after quite a few more tests, which included bringing the QS-8 in front of me... I am very sad to announced I have a bad driver... (the top one!).

I guess I'll soon renew with Axiom's customer service!
