Axiom Home Page Forums General Discussion Technical Questions Process for obtaining a replacement driver?

Why not test each speaker individually and then swap them and do the same test again. If the buzz only happens on one speaker in the left and right orientation, then it's likely a problem with the speaker.

If the problem happens on both speakers, then statistically, its very unlikely its a driver issue.

if it happen on one location (ie left but not right) then it's likely an interaction with the room.

Gives you something to narrow the problem down.
