repairing speaker cones
A.J.Lucas
an outdoor daytime gig I noticed, while looking in the back that I
could see daylight through the edge of one of the cones. There is a
split along the rim of the cone that's about an inch long. These are
the original blue bulldogs and I want to try and repair the split. Any
suggestions on how to do this? - I've heard tales of using paper and
glue, but what kind of paper and glue?

The kind made from wood and horse parts comes to mind.

Toilet paper and Elmer's works pretty good.
I've also had success with ordinary silicone caulk (no
paper required in this case) and RTF, which is "electronics
grade" silicone. Just make sure, whatever you wind up
using, to put it on *both* sides of the cone. And if the
split is where the suspension joins the paper, use
silicone, not Elmer's.

An old time guy here in Denver (who LV doesn't think as much of as I
do) showed me the Elmer's and tissue paper trick. Fixed a very old
Jensen Special Design that way -about 200 gigs ago. It works.

His work is serviceable enough, but he's sloppy.
Someone with a vintage speaker who's paying
mucho dinero for a repair shouldn't expect to
see glue slopped all over the place, or poorly
centered dustcaps, etc.

Thanks for the advices. I'll get on to it.
I'm thinking about putting some foam across the bottom of the speaker
frames to stop that pesky plug and tremolo pedal doing further damage.

Why not just tie 'em down to prevent damage?

Variations on a theme.
I dont use tp (cept for my bunghole lol .. bet you are too young to
remember Beavis and Butthead)
Anyway. I found a single ply from a sheet of two-ply paper towel works
well (saw it on a ted weber vid)
It doesnt disintegrate as easily when it is soaked with glue (I used
elmers white).
Having said that.. I had done a couple with TP and never had problems
(but paper towel is easier to work with).
The 8in I I did with paper towel I have abused on many many occaisions
and no issues either.
Your pick I guess.

So the paper's just there to provide a matrix for the glue. Sounds
like it oughta work.

Some of the Multi-ply with a mix of Elmers and water
(or whatever mix you like) is better then the old cone.
In the oldfartdays(.com) at EAW, we used to treat cones
with Elmers and water. Mid 5" speakers from Italy (RCF)
when treated were killer speakers. Wattage doubled, and
SPL increased. Later, RCF told us we were crazy..& we were.
A 1" ring around the cone just above the dust cap worked 1ders.
EAW got bought out by Mackie. A shame, KF was a great guy
to learn under, and I learned alot in Framingham, MA.
Kenton was up there with Leo, Jim, and Dave as far as legends go.

(I won't name) tried to peel it off cold instead of a paper towel and
a heat gun or something like that... took the sparkle out of it...

Remember the paper-dot trick for JBL diaphragms?
Folks thought that was crazy, too. Worked, though. ;-)

Made car payments and party favors doing it.
Folks thought I was a nut till the speaker lasted
thru the 3rd year, then they came to me to do it.
Amazing how much people have forgotten.

Oh - you said "mid" - I was fixin' to ask "wouldn't
that drive Fs through the roof?". Maybe that's what it did....

Huh. You figure it just reduced the compliance of the
