I was playing around with my AVIA the other day and I found that my M50's have a cabinet buzz at about 200 Hz. Anyone run into this before?

I'd email Axiom. That shouldn't happen.

I've got M50s, and I've never heard anything like this. However, I also haven't done specific test tones. I second what Craig said.

Donincos, you got a small red wrench with your speakers. Take the grilles off and also look at your wire connections on the back. Try to tighten anything youcabn see.

I never got a wrench with my M50's or M3's. But I do have tools. I'll give that a try. I've also e-mailed Axiom.
Tanks for the input

In my case the wrench was black, not red. Little plastic thing about three inches long. Took a while to figure out what it was for
M60ti, VP180, QS8, M2ti, EP500, PC-Plus 20-39 M5HP, M40ti, Sierra-1 LFR1100 active, ADA1500-4 and -8

Seems to me that there were a few cases of this being caused by some loose allen screws on one of the drivers a while back..

M60s/VP150/QS8s/SVS PC-Ultra/HK630
Sit down. Shut up. Listen.

Hi all,
Here's the essence of the email response I sent to Donincos. It may be of interest to others who try fixed test-tones at high playback levels:
It's likely that the fixed 200-Hz tone is exciting a resonance, probably a vibrating speaker lead to one of the drivers. If you are running fixed tones at very high levels (85 dB SPL and louder at your listening position), they will cause resonances that would not occur on complex music or movie soundtrack playback.
That said, the real question is: Do you ever hear these buzzes with music or soundtrack playback? If you do, then use an Allen wrench to undo the screws for the woofers and tweeters, remove them (the leads only clip on in one way) and see if there are any wires next to wood that might buzz. If that doesn't cure it, and you do hear the buzzes with music or movie playback, email or phone our service manager, Joe Vassallo (joev@axiomaudio.com). It could be a driver problem (it's rare, but it does happen), in which case we would replace the offending driver.

Michael_A,
Thanks for your suggestion. It often is a loose Allen screw.
The black plastic wrench (for the binding posts) should have been in the bag with the rubber feet for the M50s.
