[Jukebox-list] Wurlitzer 780 speaker

Please suggest options to replace or repair speaker for my Wurlitzer. I want to play it.   What modification is necessary to use modern 15” speaker? What speaker would be a good replacement?  I assume the original could be repaired by having field coil rewound but imagine that may be above my pay grade.  Thanks, Allen Sent from the all new AOL app for iOS
