Vifa p13 special edition!!!

Per Nielsen · 19th February 2004, 12:49 PM

Hi !!

I have just gotten a couple of vifa p13 very cheap, but it's not a version of it i have seen before it has to magnets!!
The guy i bought i from says it's a special high end version.
But where can i find the data sheet to this special version any one who can help me????

It looks like a normal version with an extra magnet attached to the back (pressumably in a counterpole configuration). What does the sticker on the side there say?

Well that's kind of the problem it says only P13!!! and nothing else... Well it's not only the ekstra magnet also the rubber seems softer...

Could be a surplus driver from an OEM production, and in that case. Good luck on finding the info, you'll need it.

But for all it's worth I would probably treat it like it was a normal version for all intent and purposes. The only real question is whether it's the midrange or the mid/woofer driver.

Ha ha.... the problem is that it's exatly a special oem produktion..
And it has absolutly nothing to do with the normal p13 I hoped that there was some one who could recognice It on the picture, because i know it is made special for a high end loud speaker manufaktor but which I don't know...
It looks like a real good and serious driver... but that's no good with out the data sheet...

But okay, I got them almost free...... So ill proberly survive...

Why no good? Just bring them to someone who can measure the parameters needed and you're all set.

Ye or indeed you could do it yourself!. The wallin jig and speakerworkshop works great for impedance ive not done TS with it yet.

The extra magnet provides magnetic bucking, i.e. video screening.

Well, that's just one thing. But also affects just about every important parameter for the driver.

Well i have found out what they are... they are from one of linn's high end speakers.

So now i just have to find a person who has the parameters on theese linn unit's.... Anyone who knows were i can find specs for linn speakers??? service manual or something???
