Hello.

I'm not sure what to do. My Harman Kardon Sub-TS7 rumbles randomly when when no input is connected.

I have tried the "reverse" option and also tried the "on/auto" option and "filter" option, all making no difference.

It used to work fine for years, then I had this issue which i had an independent repair a few years ago. Now the issue is back and I'm not sure what to do. I've opened it up and taken a look and can't see anything odd. I have removed a bit of the glue that youtube videos were saying turns conductive but this has made no change.

I'm happy to buy a replacement plate but I can't see anywhere that sells them.

As a last resort, I'm open to a replacement, with conditions being that I don't want to spend over £100, and that it should be matte black (the latter is wife's condition). See Manufacturer Refurbished - Yamaha NS-SW050 Subwoofer - Black as example.

Can anyone give me any assistance please?

I'm in North London area.


Thanks.
