Speaker repair question

bruther · Post by **bruther** » Thu Jan 21, 2010 9:56 am

Quick issue,
On one of my mids the speaker surround is coming detached from the basket. Is there a particular type of glue to use to re-attach a speaker surround.
Any help is greatly appreciated.

Most companies use this...

Thanks...I have been reading around at different sites and though "superglue" may work, my surround is rubber and it is my understanding that superglue melts rubber which is where the "super" adhesion comes into play. I was told it would work for a foam surround. I went ahead and ordered e6000. I heard it is the stuff that a lot of old audiophiles use to repair old speakers.

Thanks for the response.

I had a buddy that did it with gorilla glue

He had just finished applying a good coat when his phone rang. He recongized the caller and knew it would be a 2-3 min call so he put the speaker down, surroung side down. He didn't know gorilla glue expanded when it cured, or that it cured so quickly as after the call lasted a little long(5 mins) he could almost pick the coffee table up with the speaker

He said he picked it up a few inches when the table finally let go and fell back down....... Wish I could have seen that.

Ca glue is available at any hobby store, both rc stores as well as craft store. The only concern there is to know that there are a number of different types, some are foam safe and others eat it away........ You can find it in thin, medium and thick but I would probably go with the thin as the thick becomes very hard and inflexable. You can also find a sprayable "kicker" that will make the glue set almost instantly so make sure your fingers are clear of the glue when you use it.

That is my only other warning for it, you can glue yourself to damn near anthing with this stuff. I have a great story about an installer that glued his eye shut with the stuff on accident if you want to hear it and have the time. funny shit.....

I always thought that a slow cure silicon was what was recomended but I have never done it myself.

superglue is Cyanoacrylate I have some sitting right in front of me. You can get the activator spray like he said to set it instantly you can also get a debonder for it to help when you glue your finger to your nose.

I,ve used loctite black max on subs before and they pounded for years and are still intact to this day it takes time to set but doesn,t harden like a lot of other glues

is super glue really what people like to use?

does the super glue brand say it is foam safe?

All CA is foam safe when applied correctly. CA loves to glue to porous stuff. Of which, skin is perfect. In the case of foam, if you use a small bead of it, it will bond excellently. Now if you put a ton of it on I could see it eating the foam, but even then I doubt it would eat it far.

Both the thick and the thin have the same qualities when fully cured, they are brittle and very hard.

I personally suggest the thick stuff. The thin moves using capillary action, which is how it gets so far under your skin so fast. The thick tends to stay in place much better. If you put some thin on a speaker it could easily end up further down the surround, or run down the basket, or who knows. If you are good at using it, then the thin is the way to go as it cures much faster, but the thicker stuff would be a lot safer to work with.

I bought the e6000. I will let you all know how it comes out.

I found a funny post once in a rc airplane forum where people were telling all the stuff they glued themselfs to on accident with ca. Good stuff.

I glued my elbow to my workbench years ago when the glue bottle spilled and I did not notice it. I spent some time with an Xacto knife cutting at the glue and my arm to get free. My right arm was stuck, and I am right handed, so it was quite a pain in the ass.

So I used the e6000 glue for the speakers. Great glue. Worked perfect.
