Default Voice Coil Repair Volt Woofer

Hi there,

I have got a pair of 12" Volt Woofers out of a PMC MB2S.
They are not exactly Volt RV3143 but similar but modified by PMC.
However they got fried as a signal too hot was sent into the speakers.
So my general question is: is it possible to repair/replace voice coils from woofers?
And if so, what would that cost?

Of course, I also texted PMC already but they directly suggested a complete driver replacement which would be very epensive.

Don't know if there are companies in Germany who repair/replace voice coils.
Here in the Netherlands there are companies doing this.
A more detailed description of the voice coil (material; diameter; height; number of layers) would be needed to get a reasonable idea of cost.

Look and ask here: http://www.total-speaker-repair.nl/

Ernst Schouten, the owner, has experience second to none. Very few loudspeakers , including all sorts of exotics, and so called "specials" or modified drivers , have not passed his hands over the years. Look on the site for pictures of VC repairs.

Good Luck,
Eelco

Manufacturers occasionally charge ridiculous prices for original replacement parts.

So, do yourself a favour and check&shop pricing firstly.

It's important that new voicecoils are the same as the originals; otherwise you'd have a different woofer spec wise.
I know that Ernst buys most of his voicecoils elsewhere because it is not economic to wind them all himself; that might be different in this case.
Just ask him; I am pretty confident that he comes up with a solution.

Hm.. the problem is, that I cannot find any info about PMC 12" driver used in the MB2S .. nor do I find any info about its voice-coil.
It's a bit problematic as those must be the exact same voice coils, otherwise I will get problems with the passive crossovers used.
This is a passive system.. so specs shoudln't change.

Take out the voice coil, measure dimensions of the coil former, measure diameter of wire and count the number of turns.

Most of the claims about so called "modified" drivers are BS anyway and are often nothing else than a marketing trick in disguise to justify outragious pricing way above the standard item. If the Rdc of the so called modified driver is the same as the standard and the magnet is also the same, you can bet it is similar.
