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.

@gkelly Thanks for the tip

After dragging these out i remember that both woofer cone appears to be frozen in place and when tested no sound comes out of either speaker.  What happens to cause a cone to be frozen? These speaker were connected to an old PA Audio 200 watt amp that was powered on but not playing when they all of a sudden no longer worked. 

Simply replacing drivers with something random that fits will not get you the results you want. If you could get Polk to tell you the Thiele-Small parameters of the woofers, you could then buy something that's close and get satisfactory results for garage use. Otherwise, it's a shot in the dark. 

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.
