Ok As the title states, I have a BL 15 that locked up on me. I thought the coil just burned but after taking it out and looking at the magnet it seems that the top plate and the first magnet in the stack are about 1/8" offset from the rest of the magnet stack. I pulled the cone and coil out and yep the pole and the bottom 2 magnets along with the bottom plate are moved over. Is there suposed to be some kind of epoxy between the magnets to keep them from moving or do they just get held there under screw pressure? I have never reconed a speaker but I would like to fix this one if possible. Can I just loosen the screws and relign the magnets then put the new cone assy in? Thanks for any help.
