One of my 550 subs stopped working and on checking discovered the leads to the driver cone were severed. Nice people on this forum have advised it was over-driven. So someone was over-enjoying the sub in my absence I guess. It is on a UPS so power surge perhaps may not be the cause. I do not have a Polk dealer where I am located and I want to direct a friend in NJ to acquire the driver for me. I have emailed customer service with zero feedback.

Some resistors also show signs of discharge. Where can I get replacement parts? Driver & perhaps board?
