Speaker repair glue recommendations
« on: April 23, 2019, 11:15:41 pm »
Was given a pair of Warfedale E70 speakers. There were in good condition just dirty/dusty and the speaker grills needed replacing.

After testing the 10" driver in one of them is quite distorted (especially at low volumes), gently pushing on the cone I can feel it grating. I've removed the problematic speaker and the alignment cone (?) has come away from the basket (see pics). Holding it in place and again gently pushing on the cone and the grating is gone.

Does anybody have recommendations for glue to repair? Would be metal to paper.

Cheers

Its a spider, so:

https://www.google.com/search?q=speaker+spider+glue&rlz=1C1CHBF_enUS742US742&oq=speaker+spider+glue&aqs=chrome..69i57.3463j1j8&sourceid=chrome&ie=UTF-8

show epoxy as a common choice, which is what I would have guessed.  Although many so-called speaker epoxies show up in the google results probably the most "special" thing about them is a longer working time. You don't want 5-minute epoxy. It cures too fast--you need to make sure that the spider is accurately positioned.

Also, you probably need to clean the metal surface--be really careful not to introduce any metallic particles into the voice cone/magnet area--you will not be able to get them out without complete dissasembly.

Hopefully, you can find a good youtube video on it.

Knew there had to be a term for that part!

I'll probably just go with 30min epoxy.


Cheers

High strength (slow cure) Epoxy has done the trick.

Still got 8 hours to go before I can run it again, but pushing on the cone is now smooth all the scratching is gone.  :-+
