Speaker repair...is it easy?

Kits are for foam replacement. Gorilla should work fine with rubber. Sooner better than later.

Did the surround tear at all? Or just a clean separation? The key to a good repair is prep. You won’t be able to simply glue it back on with any adhesive with the old adhesive still on the rubber or spider. For the best results that will last, remove the old adhesive, then reattach. If the surround tore at all, it’s pretty much done. It can be repaired but IMO it’s not worth it and it would be best to either send it in for a re-cone or get a new driver if you can.

It is not that difficult but you will need a good surround adhesive and some patience and some knowledge and experience otherwise you could make a mess of the surround and the cone.

+1 millercarbon. It’s not that tough. Keep it centered as best you can and you’ll be fine. I did this to my old jbl l300 and they’re still golden after 10 yrs.. Watch a YouTube vid on it.
