Anger management and rig repair

[sonicblue62]

Behold the misdirected rage of an 8 year-old with a utility knife. While I'm not soliciting parenting advice (suffice it to say, the boy is still alive, but may be getting less for Christmas), I would like to know what kind of glue or healing salve could be used on the speaker. Will a dab of super glue do the trick? Also, any tips/advice on a good source for replacement grill cloth would be appreciated. Merry Christmas to all!

back in the day we often used fingernail polish (when in the field --- lots of groupies) to fix minor tears as your pics show. these days i'd probably look for a good silicone glue and do a tiny dab-and-spread. i'd remove the speaker and do both sides, and i'd be careful not to use too much of it. let it fully cure before testing it.

but: i'm not really an expert on speaker cone repair --- just a user with high mileage! someone will have the best possible advice. stay tuned, good luck!

FWIW: some of my decades-old repairs are still good! so there's that.

I fixed a not too good 10" speaker using smoking paper and fingernail polish, it's still working in a 20w practice amp... But sure there are better ways!

As for the grill, I have no advice there, hope you get indications from knowing users... Such a mess

Kids do these sort of things.

There’s a rubber adhesive called Speaker Service Cement that can be used. Alternately, use a rubber cement, something that will remain flexible when cured. Any speaker parts store sells repair cement.

"Black Rubber Cement Speaker Repair Glue 1 oz. Bottle" from www.parts-express.com!


Dab the area with isopropyl alcohol first to remove and dust or oils.

As for replacement grille cloth, see Fliptops Home of Parts for Ampeg Lovers.

This is the type of repair where PVA type surround glue is the best solution. This is the same substance that is used to dope the surround on the speaker. Carefully push the loose fibers back against the cone and surround then lay a small bead over the damage and gently work in with a toothpick. Then, leave it alone and let it dry. It will shrink slightly and consolidate the loose fibers, drying clear (it goes on white). The speaker will be fine.

The grill will need replacement however, this will be a lot more work and cost.

I see this becoming a big time learning experience for the kid, better to learn this now and work on a plan than discover it when they are older.

Regular rubber cement doesn’t stick that well, and in my experience doesn’t work.

The PVA glue is what’s used during manufacture by many manufacturers and is also a standard recons shop material.

Sell the kid , buy a new speaker.

I've had excellent results using "Goop" glue. It's a perchloroethylene solvent based glue that remains very elastic, fills gaps well and has excellent adhesion properties.

I’ve heard from a former engineer from Eminence that white elmers glue (slightly watered down) with tissue paper (the kind used in gift wrapping) can do the trick. Essentially look at the tissue paper as fiberglass cloth and the white watered down glue as the resin. In fact most surround and cone coatings are just variances of white glue which are also used in book bindings.

Elmers glue does contain PVA, but it’s not as stable as true PVA adhesives (especially aging and UV resistance). The true PVA adhesives are even more flexible and some have latex additives.

For this repair, Elmers glue will probably work fine and won’t need any reinforcement IME.

Yes. I’ve used it in the past to seal dust cap leaks where the cap is adhered to the cone and also surround leaks where the coating may not have been completely applied with great results.

weldwood on edge. clear pva, warm water, damp sponge, and coffee filter.. are the typical candidates.. it maybe a little bassier after.

Now's your chance to change the grill cloth to something different. Try Fender blue sparkle, it'll surprise people and maybe get your picture on the front page of the newspaper. On my Ampeg speakers, you can loosen one of the screws on the Ampeg badge a little, then grab it with pliers and tug, Velcro like pads are all that holds it on. Careful work with with scissors and a staple gun will make it an easy repair. Not sure how the grill is attached to the head, but you'll figure it out.

Ooof....sorry to hear about your situation!

Other folks (especially the esteemed Mr. Bergantino!) are much more knowledgeable about the speaker itself, but I can say that I recently bought some grill cloth from Parts Express and it was perfect for this type of application:

Good luck, and I hope someday you and the young 'un can look back on this and have a smile together.

For this repair, no reinforcement is necessary and could create issues. It’s a small non-structural repair. One of the things I used to teach when training technicians was to be sure not to create new problems and overthink solutions.

No kids I've ever known. Certainly not in my family, extended family, or any of my friends.

That kid needs some anger management training

My Ol' Man had a 1978 Ford SuperCab... two-tone blue, 4×4, special wheels, nice interior. He thought an awful lot of that pickup. My younger brother took a hacksaw to the padded dash one day. Somehow the issue became; why the ham-sandwich didn't you stop him?! The dashboard was replaced. The incident was seldom mentioned again, but I don't remember us ever being allowed in, or even near that truck for as long as he had it.
