Hey guys,
I've visited an old Hifi buddy and listened to his new open baffle project with old Fane drivers. I liked the sound and would like to copy that project but the driver seems to be a phantom. I've searched the "whole internet" and couldn't find any information on this driver.. let alone a sales offer.
It's a 12" driver and I think it must be from the 70s (the man. date says something different but I think this is just the serial number)
Here are some pics:
I don't have a pic from the front but it has a whizzer cone.
Does anybody know anything about this driver? Especially where it was mounted? Guitar amps? Organs?
I really would love to rebuild the project so any help is highly appreciated!
Greetings
Tim

they can be found....if your after 4 ohm with whizzers look for an old Hiwatt 4x12 guitar cab as my old brain recalls series wired they made for a sixteen ohm cab and two of those for a "stack" made 8 ohms.
are you certain the ones your after have whizzers?

Thanks for answering! What do you mean 'are you certain'? That's the one I listened to. If there are better ones.. I'm open to recommendations.

Old Fane speakers come up on ebay.
I built speakers for a mobile disco in 1980 and the speakers for that looked very similar to yours but where 50WRMS.
They had same label on the back.
If your looking for something new I would suggest a Fane 12-250TC which is a full range speaker.

This, the Fane 121/15 is a speaker that was used in some Vox guitar cabs, the ones with the seperate head (don't remember the model). It's a guitar speaker from the late 60's or early 70's i thought. It had two drivers in one cab linked in series (2x4oh). The amp i fixed with those was a couple of EL84 in PP config of about 20w in a seperate head. I don't know if that cab was original altough.
Thanks for the hint. It's kind of difficult to find the right one tough because there are so many different iterations. The AC15 and AC30 we're sold with Fane drivers at some time but these had 122/10 or (lauter) 122/17. The ones with the separate amps were called 'Super Twin' as I understood. I didn't find any VOX pics with the 121/15 mounted yet..
There are many variation of the Vox amps, the speaker cab looked like the AC50 MKII (big box) cab that hat rebranded fane drivers. I personally think the AC50 MKII drivers were blown by one of the previous owners and he bought the closest to the originals, the Fane 121/15 nad put it it in.
The head was certainly modified, and looked more like a JMI Vox UL710 head, not like the AC50 head. I'm not a guitar amp specialist, but i did repair/maintain some of my musician friends amps when i was still living in the city. Now i live way to far off in the countryside for them...

I had the 40 Hz version which had a corrugated paper surround.
I'm afraid I didn't see the 80 Hz version, but would imagine it had a stiffer surround and/or spider.
However, it's likely the two versions were indistinguishable by sight. It would be a matter of reading what was marked on the box!
EDIT: You can see the guitar version here: https://reverb.com/item/34051607-vi...tar-speaker-driver-from-1971-pulsonic-cone-12
Checking out a 1960s Fane catalogue, I see there was a twin cone version called the 122/10a with an aluminium voice coil instead of copper, and 40 Hz resonance.

Galu are you actually in possession of a 1960's Fane catalogue? or did you find it online? either way do share!
btw did somebody understand the systematology of the old drivers? Does 121 mean that these are the predecessor models of of the 122 series? The number after the slash seems to be the flux density (not the diameter 😉)
edit: The first two digits seem to be the diameter and the third one the diameter of the magnet pole

But from there arise some new questions.. what does flux density and diameter of the magnet mean.. not physically but with regard to the consequences these measurements have for speaker development. Does a higher flux density/bigger magnet equate to a higher quality speaker? 😵

not really a quality thing it's more about efficiency/sensitivity i.e. the ability to get loud.
The modern Fane 12-250tc would be good for your project.
You could put it in an open baffle like linked here for another 12” fullrange speaker (the other channel should be the mirror), maybe the speaker hole diameter needs to be sized a bit different :

A high flux density magnet gives a tighter, more controlled motion of the speaker cone.
In technical terms this corresponds to a low value of Qts (total quality factor).
For an open baffle we actually require a driver with a high Qts (> 0.77) which would correspond to a low flux density magnet.
The driver should also have a high frequency of resonance (40 - 60 Hz).
while that may be true i've always equated it to the drivers ability to launch the cone and coil out of the cabinet a longer distance when excursion limits are reached or bottoming out faster.
i always thought Qts stood for Q total system...
Qts is the driver's resonance magnification at its free air resonance frequency fs. I think this may be where the "s" in Qts comes from.
I regard Qts as the "total Q" of a "driver" to distinguish it from the Q that is the resonance magnification of a loudspeaker "system" or box.
But hey, I'm no expert on the nomenclature of T/S parameters!
