How can I repair crack on actual speaker?

[Terrum 10+ year member]

I accidentally cracked the speaker of my JL 15". It still works, but I am afraid of increasing the volume in case the crack gets worse.




What would be the best cause of action to repair this? If I should glue it, what would be the best kind of glue to use? Epoxy, silicone, any other suggestions? Opinions on coffee filters?

I did try search but most results seem to be about gluing the rubber/surrounds. But I apologise if this post is already answered.

Many thanks for any help!

Throw some 5 min epoxy on the back side and call it a day.

Thanks a lot for the suggestion. The crack doesn't appear deep enough for it to show on the back side. Should I use 5 min epoxy on the front side, in that case?

I just now saw this blog post: https://www.autoblog.com/2016/07/05/how-to-replace-a-hole-in-a-speaker It suggests using a coffee filter. What is everyone's opinion on this?

Yes you can use it on the front. Just going to be uglier.

Never listen to those blog recommendations. Elmers glue and a coffee filter is hilarious.

CA glue!

Actually seems reasonable for say a 50W paper cone on some old bookshelfs or a guitar cab type speaker.

The crack doesn't appear deep enough for it to show on the back side.

Which means that's not the cone but just some cosmetic bit. I like Amazing Goop brand glue for a lot of speaker repairs. Shoe Goop comes in black and may look slightly better to just smear a little on there to keep that crack from spreading. Honestly you could probably just stick some gorilla tape on there and be fine.

I wouldn’t spend on something very expensive. You could likely try and even the crack our, tape it off and use some super glue since I doubt it’s going to effect anything.

CA glue is the real deal. You can probably find some for cheaper than what I posted. That shitt is unbelievably strong when used right.
