Speaker Glue

[jdlowe13]

I purchased some speaker glue from Bill a while back to repair my Altec 515B speakers. I am just getting around to doing the repair but I need some instructions on how to use the glue as Bill did not send any. I need to reglue some of the surround back to the cone. The cone is not torn, it is just separated from the surround. Bill sold me some glue that came in a clear unmarked bottle. The glue is clear and is very thick and sticky and has a strong smell. Bill called it edge dampener CP Moyen VS6020.
If anyone can tell me first if this is the correct glue for my repair and second how to use it I would greatly appreciate it.

Thanks
Josh

Edge dampener isn't glue..it's a coating.

That said- hopefully some of the others can join in.

There are kids in college today that weren't born the last time I reconed a speaker...

Hi Josh,

The Moyen edge dampener (more commonly called surround dope) isn't a typical adhesive, as it doesn't cure. It's most commonly used to seal the mesh openings in a cloth accordian surround. It could, however, facilitate repair of a failing paper surround, providing it's not too far gone. It must be solvent thinned for application with acetone or MEK to a workable viscousity (just thin the amount you'll need at the moment). Thinning requires rigorous stirring for thorough mixing. Brush application. Safety requires adequate ventilation and other precautions applicable to working with flammable/toxic liquids and vapors.

If you could post a picture of the damaged area, we might be able to assist further.

I have successfully used black RTV silicone gasket material like they use on engines to patch up tears in the surround. Apply to back and front of the crack, and go about 1/4 inch around the tear on both sides, pressing so that some goes through the crack and smoothing and wiping off excess. Leave a thin layer though, don't scrape it clear down to the cloth again. Let it sit for a day or so. I usually put some latex gloves on so I can work it and smooth it out without making a mess of my fingers.

It remains pliable and is quite strong.

For an accidental puncture and 2-inch-long tear of my 604C PAPER part of the cone I just used a thin application of carpenter's glue on both edges, smoothed it all together with a finger on either surface and now you can't feel the slightest ripple when you run your fingers over it. Mind you it's visible, but hey.

Now I see, said the blind man.

Don't use the Moyen for either spot. Get a bottle of this, just use a light coat, remove any excess, and let it dry overnight.

What happened, somebody throw a wild pitch?

Added;

Just got to thinking, it might be better to do the repair in two stages, with the torn cone first. Various surround dopes have been used over the years, and if yours has the later gooey, sticky, gummy type (like the Moyen), the white glue might not stick well to the doped surround. If that's the case, redo that part with the Moyen.

Once the Moyen has been thinned and applied, the thinner evaporates, leaving just the Moyen, exactly as it is in the bottle. It never cures beyond that.

The problem I have with my 515B is both the glue holding the cone to the surround has failed in a small area and in other area the top layer of paper cone has torn off and is still glued to the surround. The cone is in excellent shape as only the top layer of paper is torn off and the surround is not torn or damaged.
What glue should I use to repair the two areas?
I appreciate everyones suggestions.
Thanks

Speaking of glue, I know this is not what you want to repair but I had a 400 watt 18" sub woofer that had the orange spyder separate from the aluminum frame. I did not want to pay for a recone, so I tried Liquid Nails and it held it. 5 years later and a lot of loud concerts it is still working great!
