You might have some luck by posting this over in
rec.antiques.radio+phono. I believe that some folks there have rewound
a voice coil.

Or admiration of the art of louspeaker making.
46V DC on 8 ohm 10 inch speaker, didn't last long, going o/c.
Decided to try rewinding as I've never tried it before. Found a clean way to
remove the cone from the frame. Desoldered the braid connections. Heating
the frame with a hot air gun and pushing the periphery of the cone with a
well used and rounded wooden kitchen spatula, separated cleanly from the
gummy glue.
Put in spacers to stretch the inner dust diaphragm and hot air gun heating
unglued the periphery of that corrugated disc.
I didn't expect to see what was inside. A burnt mass of wire and the
innermost end of the penetrating lacquered paper cylinder neatly burnt off
in a perfect ring.
Gap in magnet about 66 thou, paper cylinder about 5 thou thick and 2 layers
of about 2 x 30 turns of 6 thou wire (originally). I don't fancy trying to
rewind on a small paper cylinder and fixing to the remnant all with such
XY&Z precision to clear that 2x 25thou slot gap in the magnet.
For the next time anyone know of a WWW site explaining the jigs, paper
lacqering process, wattage/wire guage/turns etc ?.
Its amazing such cloth and paper art, more than technology, can take the
punishment.
