what glue to use for subs?
 

so a buddy asked me what kind of glue/silicone to use to makea repair on a sub... its a plastic cone(i think) wiht a foam surround and its starting to seperate from the cone in a spot about 3-4 inches long

so suggestions?

household goop

i was told shoe goop aswell but i think that was more for if your surround was damaged cause the shoe goop is still flexible when dry

First does the surround broke or just separate where it supposed to be? If it broke it means that he need to replace the entire surround. The problem with glue and foam (lot's of different type) is that if you use the wrong glue it will eat the foam, ive read that a few people had success with epoxy... If you can find out what is the brand/model of the sub, we could probably find what type to use. Also ask him to pinch the foam to see if it cracks, if it does that means new surround.

the seal just seperated from where it was glued down before, theres abouta 1/4" of cone to glue teh surround back on, its a audiobahn sub like this 1 pictured

Google's not my friend tonight... Can't find the info, but lot's of ppl use the "Arlene's Tacky Glue" on foam surround.

i use recone black glue but you can normaly get away with silicone

are you just gluing the surround back to the plastic cone? just use CA glue.

Permabond or LocTite brand have black CA glues. 3M does as well.

thats exactly what needs to be done... i thought of CA glue aswell but wasnt sure if it would eat the foam lol u can find CA glue at hobby shop right? is JB weld bad?
