Mystery crossovers in XPL140 or 140A
I wanted to make charge coupled crossovers for my XPL140s. I built them according to the XPL140A schematic. I was gonna pull the capacitors and wire the charge couple capacitors in their place. When I got into the JBL crossovers, everything was differnt from the 140A schematic. Different resistor and capacitor values and components in different places to name a few. Maybe they are XPL140s and not 140As? I've looked far and wide for a different schematic and contacted JBL. It's impossable to find any other schematic for this speaker. i've looked around on this site. I'm getting nowhere. I've got a bunch of parts that I can't do anything with if I can't find a good schematic. Any ideas?

Thanks for responding. I wondered if these could be some early version. I suppose they are, but there's no way to get any info on these things. I have no problem building the charge coupled portion of the crossover, but I lack the skills to design and build the rest. I'm spinning my wheels right now.
