Reasonably easy to cleanly remove one of the cones.
If a next time, to cleanly remove the dust skirt I will make a small hole
and pull with a sickle probe to cleanly remove that section.
No sign of burning on the voice coil so I could count the number of turns in
both layers if I was to rewind another. But the cardboard core that this
coil was on has broken up completely . Not knowing how to do precision
origami , looks like the end of that one.



If the voice coil former was destroyed, that would indicate that the
speaker had been vastly overloaded for a fair period of time. voice
coils dont usually go o/c without showing signs of either burning or
rubbing, tho they do sometimes go o/c in the short length between the
coil and the pigtails.
Did you check the continuity of the pigtails from the tags to the cone?,
they can sometimes look ok but be o/c. It`s often fairly easy to slice
out the dust dome with a razor blade, and solder new braids to the v/c -
there are usually solder blobs under some black paint like substance -
then glue the original dome back in.

I doubt that the original speakers are worth reconing, but, Wembley
Loudspeakers will sell you voice coils, cones etc., if you know what you
want, and ask them nicely.
