I have an old 12” Philips woofer but I do not know the designation.
I believe that it was made between 1970 and 1975. It has rubber surrounding.
Which is the designation?
Which is the Thiell and Small parameters?
Best regards Jaime

I can't see where the insertion of humor would be 🙂
T/S params can easily be obtained on an unknown driver with equipment I'm sure >50% of us have:

And the numbers stamped on the frame are traceable online with popular manufacturers, like Philips.

I feel the idiot question
The driver is inside an enclosure.
I had an hemiplejia and manual work is very difficult. I need to ask another person to open the box.
I believe that Philips must not have made many models 12” woofer, rubber surround, between 1970 and 1975.

Jaime,
I´m from Montevideo, too, and I have some long, long affaire with philips drivers, so it is possible that digging deep in my library I could find some specs of that driver of yours. Usually, philips woofers were designed to be used in acoustic suspension alignments, giving optimal volume as one of the few parameters in their catalogs, but fullrange ones as the 9710M and for instance AD12100M were best suited for alignments such as bass-reflex or horns, where no high x-max were needed or wanted.
Cheers,
Mar
