Frozen cone on a Vintage 30, any ideas?

[blackba]

I just got a Marshall 212 cab. It came with some WGS speakers inside, but the seller also shipped the original Vintage 30s. One of the Vintage 30's has a frozen cone. It does not move at all when you press down on the cone. I mainly wanted the V30's to put the cab back to stock if I sold it.

Anyway is there anything I can do. I though about doing the 9V battery trick to the terminals or hooking up to my SS stereo and slowly turning up the volume. I am thinking its probably time for a recone. Its been years since these speakers were used and the seller claimed they had a bit of cone cry when he last used them.

Two things are possible.

1) Voice coil melted so bad it siezed.
2) Speaker was dropped or jarred so badly that the magnet shifted and is holding the voice coil in place from pressure. The voice coil is shot since it's been pinched.

For #1, a recone fixes it. For #2, recentering the magnet and a recone fixes it.

Either way you could probably buy a current/new V30 for the same money...or less. Sorry.

I've been there and done that with an old BlackBack G12H30, so I know it's one or the other. In my case it was #2. OCSR (Orange County Speaker Repair) did the work for me.

$65 for the recone
$38 for the mag re-centering.
$78 for the original speaker I bought through eBay.

Total for a reconed G12H30 to make it like a 70th Anniversary...$181. At that time G12H30 Anniversaries were $68 each plus shipping from Avatar. Pretty sure I could have had TWO new speakers for the price of that old BlackBack after the repair, and had a free lunch with a couple of beers for the difference.

Good luck!

Thanks for the reply Scumback speakers.

I thought did not think about the magnet shifting from a hard hit. That certainly explains why I had a similar issue with an EV EVM-12L in a mesa halfback 412 cab. The cab was handled roughly by DHL and the driver came loose. The cone on that speaker was seized as well. I was shocked that an EV could blow in a 412 with a guitar amp. Now I have a new theory as to why it failed

I was actually not planning to use these V30's, I just wanted them to put them cab back to original, so just buying another V30 (which won't have the marshall label) kind of misses the point on why I wanted them included.
