ID these horn drivers?Mystery Solved!

[Mr. Snoid]

They are Beyma CP850dn drivers!!  Made in Spain by Basque Sound techs.

Can anyone ID this 2" opening 4-bolt driver that came off a large format stadium horn setup? There are no numbers or brand ID at all. Probably an early 1970s vintage.

Thanks,
Tod

There's only a few 2" makers. JBL Gauss Meyer clung to Alnico but this is ceramic.

E-V seems most likely.

Thanks, PRR. I wonder if I pull off the cover I can tell by the diaphragm. Hmmmm. I've been googling for hours and never saw anything even close, though. The EV stuff looks closer to what I have though.
