If you lower the volume knob on the VTF amplifier, and increase the subwoofer channel level on the A/V receiver, does that help at all?
I have tried that before and it did not help. When I just turned the sub on, to test, the sub was on, but I hear an almost wind like buzzing noise, when bass is put through the sub, its "flappy" or "echo-y"? Sorry for the non-technical terms, but I don't know how else to describe it?
What would servicing require? I live in Irvine, and bought this sub almost 10 years ago out of your shop in Anaheim.
