My dad brought me his unused late-2000s #Bose Lifestyle V20 surround sound system. It has 5 tiny dual-cube speakers that connect to a massive "bass module" which connects to a Bose AV receiver.
It could've worked great with my PS5 but the bass module is dead as far as I can tell. It's a damn shame but it looks like he could get a good amount of money by selling it for parts on eBay.
@oldthink34 I was the person who would buy the parts. :D That's the successor system to what I have. He / you could also get a replacement for the bass module on eBay.
