Any Idea What Pro-Series drivers these are?

Check out the stage monitors, especially around the 4:00 mark. Look like D130 and LE175DLH, but would anyone (but me) have used such a combination professionally in such an application?

That combination was quite common for foldback in the '70's and '80's. Judging by the silver ring on the HF driver I would say the are 2301's.

My favorite monitor was D or K or E 130s with a simple bullet tweet.

There were times when a dual twelve K or E 120 and 2370/2425 type horn was better for acoustic performers.

A club here still has dual E120 with 2402 bullets for monitors.
