I had a speaker almost as bad as that so I reconed it. I was able to attach a new cone to the spider. There should be a bolt holding the spider in. Is your missing? You will need that or the cone will not stay in the core. I see the speaker is like my 91 where there is a ring around the outside edge that comes off allowing removal of the cone after you unsolder the voice coil wire from the transformer. The cone I used had an inner diameter smaller than the spider so I carefully cut the hole bigger and then glued the cone to the spider. The ring holds the cone so no glue is necessary on the outer diameter.

Hope that helps somewhat.
