Funny coincidence...I'm currently in the hunt for a replacement speaker. Becker of North America may have an exact fit new speaker, but I'm in the middle of checking out the dimentions. Looking at pics they sent, their part #018-872-882 just may be it. They also restore old Becker radios, may do Blaupunkt at well?
www.beckerautosound.com Their toll free number is 888-423-3537. If their speaker doesn't pan out, I've found a reconing service that says they can fix my original speaker for $50 plus $7.50 shipping. You can email them @
rjmcgee@voyager.net. IF the new speaker from Becker doesn't work out, I plan on shipping to them, waiting the 3 weeks turnaround they stated.
