A known issue, eh. That's good, and I'll try unplugging the power, as a diagnostic. I'll call Axiom soon, but for a little while, I'm going to be listening. The person who sold this to me seemed to think it was an EP175. Should I feel guilty?
Caveat venditor!
If this is the system you mentioned over at AVS and you can get the sub working properly you got an awesome deal.
