Friends,
I will shortly (I hope) receive some drivers of pensionable age. Being a total electronic ignoramus, I'm hoping that someone here might point me in the direction of a person who could measure their:
(a) TS parameters; and, ideally,
(b) sensitivity & frequency response.
Melbourne (great southern land) would be handier than Vladivostok.
All guidance gratefully acknowledged.

Which drivers are they?/
Some-one may already have ball-park figures
When you say pensionable age I think of a driver from the 50s, how old are they? and how big??
Regards
Ted
PS I can't help with the measuring NO gear as yet

Goodmans.
Goodmans of England, old chap
12" triaxiom - 1960s some time, swinging London and all that.
They're re-badged as Lafayette.
The Lafayette model designation is SK217W, and I haven't been able to find the corresponding Goodmans model number. I don't think they're 212C, could possibly be 216C (which had larger magnets), but there are several other possibilities.
From what I can gather, Goodmans made their co-ax drivers by putting their Trebax horn tweeter inside one of their woofer or wide-range units. A variation on the Tannoy/Altec theme.
Most likely they're fused solid, of course, and my enquiry is totally pointless ...

Well anything can be rebuilt; whether or not it's cost effective is another story.
Perhaps some-one on the forums has the original XO data.
Definitely not my cuppa char, but the sound may make searching more than worth while

Iv'e got a Woofer Tester 3. It seems to do a fairly good job of the TS. I don't mind measuring them for you if you can get them to/from me.

Thanks, Col - sounds champion
I'll email/PM you when they hit our shores and see if we can't hook up.
Cheers

oh well - too late now, since I use this all over the place. Maybe I'll attract the interest of some with unusual political views ...
