Saw this advertised as a "JBL crossover, 60's" but it doesn't look familiar to me in either any 60's crossover or later in the consumer or Professional line. The seller thinks it should be a 3 way, but I didn't ask him to trace out the wires and I didn't get any other pictures. Maybe it could be a two way? Don't have any info if there were L-pads or controls.
I did get an account of some of the crossover components.
"THE VALUES ARE BETWEEN THE CAPS. 16.5 UF, 16.5 UF, 13.5 UF, 3 UF, RANKED BY SIZE. THE INSIDE RESISTOR IS 38 OHMS, THE OUTSIDE IS 3.9 OHMS. THE MIDDLE HAS GLUE ON IT. THANKS FOR YOUR INTEREST."
Given the values, I'm thinking something like a 12" or 15" woofer but other than that, I'm stumped so far. I've gone through the available JBL Pro schematics on their website, looked at possible candidate in the Consumer tech sheets, and not come up with anything yet.
Anybody have a clue or does it look familar?
