Subwoofer fix

[lilred]

does anyone know how to fix cracks in a sub. My sub decided to run around in the back of the festy and now the cone and foam have cracks. Is there a way to fix this

no. Generally you can replace the foam surround, but not the cone. You could try doing something with epoxy, but be aware that changing the mass of the cone will change the response of the speaker.

This is a good question.

Natty, where do you get/buy the foam surround to replace it??

What I use to do for patches and cone fixes has got to be the most "redneck" fix ever.

HERE GOES:
Get some toilet paper, clear finger nail polish, and a black sharpie.
Place some finger nail polish around the area needed of repair, do not allow to dry yet. Then place a pre cut strip of TP over the damaged area, the edges will stick. Once it is set how you like it, start appling more finger nail polish over the whole patch. You should know it is enough when the TP almost becomes transparent. If needed add more precut pieces over the 1st layer, and reapply the fingernail polish. ALLOW to dry. Once the patch is dry grab your sharpie and color away. The end result is very close to being the same consistency as the original foam, if not alittle harder.

This might sound way out but I have used this little trick on a set of
12' JL w-6s many of times over, and it has worked just fine.

yes, that is essentially fiber-reinforced enamel. You could do the same thing using 5-minute epoxy but only use a small amount of epoxy to keep the mass low. I like your method ACE.

The foam surrounds are usually sourced from a speaker distributor, but I just recently saw them in my local electronics/surplus store. If you buy them from the speaker manufacturer, you pay a ridiculous markup.
