cone cry

I've got some greenbacks that are making a weird moaning sound when I play an F# on the B string (7th fret). Is this what I've heard referred to as "cone cry"? How do I get rid of it?

Randy...This is a Celestion term I've heard over the years...You didn't hear this phenomena before you replaced to the Greenbacks right?
Realize an amp that is in need of filter caps can do the same type of thing you're talking about...It's this out of tune weirdness heard usually on the B string 17th fret...I've also heard the term "edge howl" and I don't think there's a cure other than different speakers if the problem is the speakers and not your amp? Celestions are noted for this phenomena though...Once you're used to tuning into this,it's hard to ignore it..

High F# above the 12th fret of the B string? I've heard that. And it was cone cry. I've heard it in Celestion Vintage 30's. Well...just don't play that note! :D

Or: you could get some rubber cement and do a little extra layer of dope around the edge surround...that's what that shiny stuff around the edge of a Celestion is for. It dampens cone cry and edge yowl.

But to much will also dampen the highs a touch and make the speaker sound a little less lively. Don't overdo it!

It can be removed with Acetone tho.

My brother Bruce came up with a trick for making speakers livlier and deeper sounding that has been adopted by Ted Weber. But Bruce thought of it.

He hooks a new speaker up to a sound source and then takes a soldering brush and little bowl of ACETONE and keeps painting the edge surround of the speaker with acetone while the speaker has music or a tone from a signal generator playing through it.

The speaker doesn't have to be mounted...he just does it to new speakers sitting face up on his work bench.

The acetone removes the edge dope but also softens the paper and edge surround and the speaker opens up and the tone gets deeper.

It works! Works especially well on some of the new Jensen RI speakers like the C10Q which is kind of thin and bright right out of the box.

I believe Matchless may have done something similar to the ACETONE trick to the Celestion speakers they used in the original Matchless amps. Mark Sampson was secretive about it, but I'll bet it was something similar. Lew
 
let me see if i got this right...

hi lew, thanks for the reply....

are you saying that

1- you can stiffen the edge w/ glue and kill the cone cry

or

option 2- you can soften the edge w/ acetone and kill the cone cry that way

Either way works?

PLEASE RESPOND... BIG NASHVILLE SESSIONS COMING NEXT WEEK!!!!!
 
I'm saying you can often reduce cone cry by adding a little rubber cement to the surround.

And that a speaker with no cone cry can often be made to sound more lively and deeper in tone by doing the acetone trick to remove that dope.

No...adding more dope or a layer of rubber cement to the surround will tho.

And if you add to much, you can remove it with acetone.

Go over to the Weber VST forum called "Amps N More BBS". Go to the speaker page on that site and ask Ted Weber about this. There may even be a faq there about doping and cone cry. ;) Lew

I think you're right, Lew, about that trick being used by companies like Matchless. They use different buzz words for that teqnique like "custom voiced" or whatever.

I've noticed that buzzy undertone thing, too. I never heard
the term "cone cry" but I hear it sometimes on different notes on the B string and occasionally on the D string. Nowhere else.
It must be that the note is tuned at the same resonance note
as the cone, or something like that. It bugs the hell outta me.
