Can you give more details? How long have you had the EP-500? What appears to be the issue with it? No power? Clips?

The EP-500 is not a cheap subwoofer with a current price of $1800! I can imaging a new power amplifier complete with electronics probably was quoted around $600-$900? Is that ridiculous? Depends on how long you've had the EP-500 and what led to it's demise I guess.

I know that for my EP-175, Axiom quickly sent me a replacement back panel (under warranty). Likely cheaper than shipping it back and forth and spending lots of valuable tech time to diagnosis which piece(s) were damaged/defective.
