Please help ID these Ampex console drivers?

[pabs911]

I got this Ampex console about a year ago, but most of the innards were replaced (made a thread about it here), but I just decided to see what speaker drivers came with it, so I opened it up. Here is what I found...

Vintage 1959 Ampex Model 1702 console...

This 12" woofer is in outstanding condition except for 51 years of dust that wouldn't completely come off. It's branded Ampex, but I've read that JBL and Altec had dealings with Ampex. Could this woofer possibly be a rebadged Altec?

Any idea what this midrange or tweeter are? BTW, I am looking too, so don't think I'm being lazy. I just know you guys are well versed in IDing vintage drivers like these.

Well, even when I use my Super Secret Spy Decoder Ring, I can't see your images.

Really? They should work fine. Try reloading the page please.

I am very confident that those components are neither Altec nor JBL, but they do seem to be of above average construction -- alnico magnets on the woofers with a proper magnetic circuit.

what does that stamp on the back of the woofer magnet say?

THe bell cover makes me think of University.
Look for an EIA code number: www.webervst.com/codes.html
Doesn't look like a JBL or Altec product to me.

Stephens maybe?

The baskets have a rather Audax/Rek-o-Kut look.

I couldn't find one, unfortunately. I did put them into my Dahlquist DQ-10s with great results however. Now I just need a high current amp to mate with the Dahls.

Those don't look familiar at all.

When I worked for their broadcast equipment division in the late 70's they used mainly CTS drivers and all those that I saw had CTS stamped on the magnets.
