Old Jordan drivers -- specs?

[rongon]

I inherited a pair of old Jordan drivers. I think they're the original 50mm Module. They're black, and on square mounting plates. The thing is, the mounting plates do not have any mounting holes, so I'm not sure how they're supposed to be mounted on a baffle.

I looked for info on the web but couldn't find anything for this old style. Does anyone have info on these, or a link to info?

The EJ Jordan site does not have info on these old drivers.

Thanks

I might have an old data sheet around somewhere, but I can't promise I'll find it real soon. Send a message to me by PM so I won't have to search for this thread to contact you again.

I got rid of a pair of the original drivers about a year ago. I did measure them at the time
but didn't save the measurements. One thing I did rember is the FS was about 210 hz
and the QTS about 2.5 . Yes a fs of 210 hz and a QTS of about 2.5 I assume the suspention had hardned over the years. Tou realy do need to measure these drivers!

Measured last year, my original 50 mm 1982 modules had a Q about 2.8.
I may still have the old data sheets with an Hifi News article somewhere.
