JBL Paragon Speakers

Does anybody know anything about these speakers? I have them in my basement and don't really know much about them.They are in a single cabinet that can be split apart that is 8'8" across by 35" tall by 2' deep.They have two horns at the front of the cabinet with two large woofers in horn loaded enclosures.The model number is C44 and serial number 41656.The horn model is 075 and has a serial number of 84724.I beleive they are from the early to mid sixties.Any help or insight would be much appreciated.
