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!

I have 2 VP-150s and 1 M2ss from the same era. I think the drivers are interchangeable between those models and the QS-8 so I can have my system back before long?

After a few days with the M22 driver, everything sounds good! But I have to admit i'm getting impatient to stop listening for the buzzing. Anything there is a strange "human moving" sound in a recording, my head lifts up and I try to locate the "problem"... Sound I'll to go back to just enjoying music!
The replacement driver is "on vehicule for delivery"... but i'm not home. I guess tomorrow AM I'll have to pass by Purolator depot to pick it up!

Guess what? The matching QS-8 has developped the same issue (hyper vibrating top driver).
I swapped with the drvier from my spare M22 and it stopped. BUT, I could feel the whole speaker was strained (whole QS-8 cabinet shaking too much for a speaker).
I was using a xover of 80z. I uploaded a new one at 115hz (the recommended xover by Anthem's ARC measurements) and the speaker is no longer strained.
Should receive an answer from Axiom soon. In the meantime I'll if I can notice the xover shift. Maybe I'll it better!

Just tapped into my denon through the web interface to check my surround crossover setting....
My Q's are crossed over at 90hz and I haven't had any problems in 3 years.

Sounds like there is an issue other than the woofer. Could be a defective crossover. You should send the whole QS8 back to Axiom for diagnostics and replacement. There is no way in hell a surround speaker should be shaking like that especially with a crossover point of 80hz. What kind of source material is going through the surrounds?
I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
