I bought a pair of JBL E140s on eBay. those are the ones with the big ceramic magnets. They were "broken" so I knew I would need to recone them. However, on one of them the center pole piece is no longer attached. It was wedged against the coil so tightly that I had to pull up the voice coil on the opposite side, bump the frame to move the pole piece to the opposite side, pull up on the newly freed side, and repeat until the voice coil was completely free.

1) Can it be repaired?
2) If so, how?
