Hi all, I came across a nice deal on a pair of JBL cabinets which I believe were sold as kits manufactured in the late 60's or early 70's. I'm trying to determine if these are actual JBL produced cabinets or something else. They measure 24" W, 25.5" H and 18" D. They were loaded with very nice and fully functional D-130/LE 175/ N1200 . Any help on the cab ID would be appreciated.
