Hi Folks, I'm looking to semi-upgrade my home theater system that is 11yrs old. I'm planning to keep the 5 bose speakers and ditch the receiver + subwoofer (bose set the hpf/crossover to like 200hz and there's no way to change it). Now I found a polk subwoofer (psw10) for $99, but I'm having trouble finding a receiver. It doesn't have to be feature packed since it'll be hooked up to only my pc. Any suggestions? Thanks in advance!
