I recently went thru that with a different brand of speakers and they (the company) wanted $300 for a new woofer X 2 since they said the woofer had changed so they wouldn't sound right otherwise.
I bought these speakers used cheaply so there was no way I was sinking that much in. I got lucky and fixed it myself with a little glue and some solder.
If not I found a after-market woofer online I would have tried from Madisound.
