I have the same problem with my EP125; Joe in service was very helpful and I sent the sub's amp section to him for testing and it was performing to spec. I've 'sort of' solved the problem by adding +10db in my receiver and another +10 via an old equalizer that I put in-between the amp and the sub. However, this works out really badly at higher volume levels and I'm always having to adjust the equalizer to different values. I wish these subs had more sensitive auto on/off circuitry, or the ability to bypass the auto-off feature. I'm a little conflicted about the whole thing, in that Axiom was super good about looking into the problem, but in the end the product doesn't meet my (and apparently your) needs.
