Ampex 150-4 15" Driver?

Hello,

I am wondering if Ampex 150-4 15" drivers were made by JBL? They are rated at 32ohms, thank you.

Yes they are OEM JBLs. In the early days (through the 60s actually), JBL made speakers under various OEM arrangements. They made them for Ampex, DuKane, Heath, and probably others. These drivers are identical to stock JBLs with different paint schemes and labels.
