Thanks for taking the time to write up your experience. Correct me if I’m wrong but didn’t you already replace the amp in your first EP800. If so did you ever ask Axiom what if anything the found wrong with it?

You’ve also been very patient through this. Any chance your going to try another amp? Ever thought of getting a smaller subwoofer like the EP500 and adding some Buttkickers to carry the very low end. Good luck finding a sub that goes as low with as much authority as a Buttkicker, not that there‘s much 5Hz material out there.
