Speaker Cone Repair Tips/Tricks?

[JohnnyCrash]

I’ve got a vintage speaker that has a very small rip in the cone.

I have the black goo speaker repair sauce stuff, but before I use it, I wanted to get your collective wisdom on the best way(s) to repair a torn cone.

Johnny,

Scan through this recent thread:

Several posters on it offer some good ways to repair a torn/ripped speaker cone.

Edit: ..Or is that a Ripped Torn speaker???

I use coffee filter paper but I can’t remember why.
Must have red it somewhere and it works for
me.

I think I used titebond on some cloth for this one with some black nail polish to seal it. 5+ yrs old now and hasn't let go..

vacuum cleaner accident,.. I really must make a grille for this cab one day..

If it really is a "very small rip" then a small dab of a flexible adhesive will do the job.
Is the tear near to the surround?? That's where adhesive flexibility is a mandatory requirement!

A lot of things work. I've gone to simple silicone sealant on both sides for flexibility.

Coffee filter soaked in white glue ( like Elmer's) worked great for a pretty big tear I had in an old Oxford. Super easy, too.

I like to use the paper from a US bill. A large tear is the perfect candidate for the entire pic of George "I Cannot Tell a Lie" Washingtom. Elmer's to affix it.

Speaker cones and glues used on them need to be a little flexible. If you use a glue that sets hard, like CA, it can make matters worse--especially around the suspension (the part near the rim that's corrugated).

Aleen's Tacky glue has been the go-to in the audiophile community. Stays flexible and is easy to work with - very thin and light. Available everywhere.

I've had to fix a lot of torn speakers over the years, they're much cheaper when you buy them that way.

Anyway, I got my recipe from Ted Weber and its the only thing I've ever used.

Weldwood rubber contact cement (red) thinned down with some Acetone.

Works for me, they're all still holding up.

Small tears I used clear nail polish

I use Pliobond as the adhesive, and occasionally a product called "book mending tissue" which is a very thin, surprisingly strong tape made of long fibers and archival adhesive. It becomes fairly inconspicuous once applied.

Traditionally it used to be nail polish or rubber cement if it is in a flexible area. Now days there are a lot of different variations on the theme. I have not tried it but fabric softener sheets are also tough as nails to pull apart but I think you might want to get the smelly stuff off first to insure a bond. I think the shoe glue should be fine if used sparingly.
