If you need to replace/rebuild the driver, go to Madisound:
http://www.madisound.com/catalog/index.php?manufacturers_id=125&osCsid=26513875b73e10120b3bf3906b8ff8a3)
They can rebuild Dynaudio drivers and are authorized to do so (they were one of the vendors that sold Dynaudio drivers to the hobbyist 10 years ago). They have the related $$ charges for rebuilds on their website (per model). However, you have to send in your drivers to prove they are "authentic" Dynaudio drivers. What they actually do is completely replace them with new drivers (on an exchange basis).
