They quoted me $46 shipped for the mid range. That seems pretty reasonable. The woofer is probably a little more, but I've got to believe it's less than $100.

Mine's not quite as bad as the picture above, so I may try to live with it for a while. Then again, I'm anal enough that it might bother me until I spring for a replacement. In my mind, I picture it distorting the sound waves but I don't know if that really happens.
