Anyone here familiar with the JBL N600 crossover?

I have a pair of these, but it's pretty obvious that they've been modified, presumably by their former/original owner.
They are not very sonorous when interfaced with JBL 2441 drivers for HF and the LF sections of Altec 604E for LF.

I am tempted to attempt to reverse-engineer these back to their original state (even though I recognize that it might not be worth the effort).

In other news, glad to see our neighbors to the North have their priorities in order.

Does anyone happen to have a schematic for these (or even the color coding of the original wiring) and/or an unmolested example that one might be willing to photograph the innards of -- for comparative purposes?

I did search here (and also pretty much everywhere else, via Google) but didn't turn up much info at all.

Thank you for your consideration!

Hi all, am a newbie to the Forum. Like Mike Hardy, I am in need of a schematic diagram and wiring info for the JBL N600 Dividing Network used in the Metregon. I have a pair that I wish to recap without having to de-encapsulate the existing components. Am hopeful that the wiring data and schematic info regarding required values for the crossover capacitors will enable me to do this. Thanks for any and all help.
