any ideas?

I have a Rythmik sub that I have been using for several years in my system.  It is connected via high level ( speaker cables from amp) interface.  It has always been quiet and actually a great sub.  For the past week or so, it has been making a mechanical buzz - NOT thru the speakers and not changing with volume.  Absolutely nothing in the system has been changed for several months nor have any changes been made in where things are plugged into.  Does anyone have any suggestions as to what might be the culprit?  The buzz  is annoying when no music playing, but the sub still seems to function perfectly when fed a signal.  I am at a loss..

If you can download and play a low frequency bass cadence of low frequency test tones their continuous play length should allow you to more easily locate the source of the buzz.

Once located, contacting the manufacturer should offer definitive suggestions or options.

Good luck with it.

Carry the sub to a different room on a different circuit and plug it in. See if the buzz goes away.

If the buzz is 60 HZ it might be the power supply transformer mechanically buzzing. I'd call Rythmic and ask. I have one and they are good folks to do business with.
