How difficult is it to recone?

[Rottweiler]

I just swapped speakers in a 20 year old 2x12 and the speaker cork was stuck hard to the baffle.

This is a 20 year old Avatar Hellatone 30 aka g12h30 70a. Its a shame as these were solid speakers and well broken in.

Is it a PITA to recone?

Does the speaker sound as good once reconed?

Black silicone RTV and glue it back together. I've seen those RTV repairs last years.

Super glue the cork area and the Silicone as suggested for the speaker surround

I tried my hand at reconing a couple JBL's because my local dude died in 2019 and after 2020 those cones shot up in price. End result, one had a coil rub when it was done, the other one came out working fine but my work wasn't pretty. It's trickier than it looks but not impossible. There are tools of the trade that make things easier but would cost extra money up front.

If the speaker has any value I would just put it in the hands of a pro. As the fellas mentioned, you should be able to patch up what you got just fine.

I get the superglue under the cork section, but my question is on the black rtv on the torn cone,

Would you smear the rtv on the entire torn black cone surface and basically use it like a glue?

or would you glue the cork, and apply black rtv around the perimeter of the black cone tear? This would leave a slight air gap between the black cone pieces and might buzz?

Thanks for your comments!

Glue the cork. Let it dry. Then put a little bit of the silicone rtv under the ripped part of the surround. Carefully smooth the surround down and apply a little to the top now. Smooth it down and follow the shape. What you are basically doing is just using the rtv to fill in the gap from the rip and keep it stuck to the cone. Sort of like frosting a cake. Smooth it and work it around so it looks like the rest of the surround. Let it dry and it should look like nothing even happened.
Just be careful and don't go crazy using too much... Wear gloves too, that stuff is sticky and icky
