I have a pair of Turbosound Inspire iP500 powered speakers which have the same problem.
One failed maybe a year ago by not powering up and upon opening the amp module an electrolytic cap in a potted area of the board was domed on top. Given I don't see a way to remove the potting without damaging the board, I haven't fixed it.
The other one failed in the same way and likely could be the same cap.
Is it possible to wire these up to use an external amplifier with either a passive or active crossover or does the stock amp do some sort of processing that would make the speaker sound bad doing it that way?
