Bose acoustimass 5 Ser 2 - rattling bass module?
Inherited a Bose am5 Ser2.
Seems fine until I crank it up, then the bass module starts to protest with a resonate rattly noise on deep bass notes, however if I lay it on its side and lean on it/ put a pile of books on it, all seems OK....
Any diagnosis thoughts welcome
TIA
