That needs a complete recone. You can jury-rig a patch on a table radio speaker with white glue, but you don't want to do that on a high-fidelity speaker like this. It's a waste of material. And the spider is shot too. No amount of "break-in" will fix a sagging spider - it has stretched.
Get a full recone, and make sure it is done by a good technician using genuine JBL parts. If you don't know a place that you're sure you can trust, send it here:
