Thank you for the suggestion to reduce the 200Hz EQ setting, but the speaker(s) haven't always done this and they shouldn't now. But, yes, I agree, the system is terrible to begin with.
It's not the speakers, or the amp. I have the same problem.

The sound is crystal clear at very high volumes, but at certain resonant frequencies, the metal grills will buzz. I believe this is the problem.

Artist: hankat
Song: be the first, rosenstand remix.

This song will reproduce the problem. You'd have to be a deaf service advisor not to hear the problem,
