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?
