Good morning. I’ve tried everything I can think of to figure out how to get my sub to stop the occasional vibrating, screechy, hum sound. Mostly noticed with television, low volume levels. I put acoustic foam underneath thinking it has been shaking a wooden cabinet, but I don’t think that’s it. Any suggestions? Lot to spend for a sub that puts out an annoying sound.

If the noise level does not track the Volume control, SUB must own it. I would take this up with SONOS support.
