My list is short. Aside from a Cambridge 5.1 system I bought for a computer back in the '90s, which had a bass module of sorts, I never used a subwoofer with my audio gear until 2012. My mains dig deep enough that I didn't consider it worth my while to buy a sub until I could justify a pretty big one.
