If it is indeed a Floyd Bell speaker, DigiKey.com is a distributor.Yes they are expensive. Is it a Floyd Bell?
Oh I already ordered a new one from Autowash Maintenance and it's on the way. I just wondered about the possibility of repairing or rebuilding the old one and keeping it as a spare.
How much was that?

At that price, it would probably be worth getting an electronics repair place to look at it. Sometimes its just something simple that went out. Like $1 worth of capacitors making a computer monitor not work.
