Bowers&Wilkins ASW675 10" Sub, blown driver. Can't find anyone to repair it.

Starting to feel like I'm supporting this B&W Sub.  Two months ago the amp had to be replaced.  Now the voice coil is loose.  Sent it to two shops that said they would try but cautioned that B&W does not sell repair parts for these drivers.  At $600 for a replacement, that's a bit difficult to handle.  Does anyone out there know of someone that might be able to help?  I really like this sub, just not the maintenance.  Thanks in advance, Arkelectric.
