Finally placed an order for the ep500 (after almost pulling the trigger for the SVS pc ultra)and QS8's. Funny, I received everything BUT the sub. Seems like Purolator forgot it in TO. Just my luck....

Anyways, don't laugh, but prior to this purchase, I was using an Athena P3 for a sub ( along with m60's and a vp150). But suddenly, out of nowhere while listening to a Mr. Bungle CD at moderate levels, my sub started making this weird flapping sort of sound, then all bass was lost.
After turing off the music, I noticed a pretty loud buzzing sound coming from the sub as long as it was plugged in to the AC outlet. If I would unplug it and then plug it back in, It would make a weird popping sound then start buzzing again.

I opened up the sub, looking for anything that might have disconnected, but all seemed well.

Anyone have an idea of what might be wrong? It isn't the end of the world, but if it seems like a minor problem, I wouldn't mind fixing it and keeping it as a spare.

Thanks guys...
