The voice coil will be replaced during the reconing process. Reconing replaces all the moving parts in the speaker frame: voice coil, spider, cone, surround, dustcap, leads and sometimes gaskets if applicable. Sometimes with certain hard to find or odd shape/size cones, an attempt is made to recoil only. It is much harder to do than a complete recone because the original cone must be saved and the orig adhesives removed, all without damaging the cone. Usually the spider will be replaced with the voice coil because it is almost impossible to save one.
Options are aftermarket recones or factory JBL recones. I can give you more info if you need it.

Thank you for your response.
The reason for the request is an attempt to salvage the original 122 cone with its aquaplas. I thought the replacement is a lighter assembly and of course would change a lot of numbers.
Do you know where an exact replacement can be found?
Thanks again.
