The woofers are fried due to a lot of amp clipping at loud volumes. In other words, it was played too loud and fried the speakers. Crossover could be fried as well.
Replacement Woofer for Polk TSI 100
Got a pair of these with dead woofers. Polk wants a bunch for new five and a quarter inch replacements. Whats a good place to look for a replacement woofer for this little speaker that will be used in the garage if I can fix them.
