Those I believe are made by Audax.

those might be RCF pro drivers made in Italy

@ Djim

Hi, looking at the plates on the back of the magnets, they "appear" similar to B&C and BMS drivers. Also the BMS recessed areas around the rear mounting circumference has a similar casting.

These links are just for a quick comparison, & as they are new models & yours look older ones, i wouldn't expect they would look exactly identical anyway !

Thanks so far, RCF never used these connectors...
B&C doesn't use these these connectors either and the backplate is flat.
Any ideas which Audax types?

Not now, but "maybe" they used to ?

Ahh, it looked curved from this photo !

Hope you discover what they are, let us know

Agreed, their pro version of the PR330 IIRC ['X' in the model #].

If it is an Audax, you might be able to find it in here AUDAX, LA PASSION DU HAUT-PARLEUR

There are several PR330 models, but i don't see PR33LTX350 ?

Happy hunting

Jep, seems 5th Element and GM are correct

,it is definitely an Audax PR330 driver.
So far the PR330T4 comes most close. I guess it's something custom made Zero D cause I also can't find any info specific to the PR33LTX350.
