Closest I could find was

JBL Professional Series Floor Standing 4560

I am thinking the Tweeter is model number 075 from the 70’s.

I actually OWNED this tweeter as part of a 2-Way design.

My housemate, when i was failing out of college, owed me money and took off, kind of leaving his JBL’s as my consolation prize, lol. They were a BIG part of what got me into this hobby. Roommate had done work for a doctor and got the JBL’s as part of that deal. They were really top of the line, like normal folks could not even afford them.

The boxes were beat up but the drivers were the real deal. They could bore a hole through your brain before you heard any distortion, haha!!
