Sounds to me as if you will have to replace the drive unit. B&W has them in stock here: bwgroup-support.com
Subwoofer Rattle
I have a B&W ASW850 subwoofer that is rattling in the 20-40Hz range (tested with a signal generator). Although I have never consciously over driven the unit, I assume this just means the voice coil is shot and I need to replace the speaker? How easy is this to do?
Thanks for your help.
