    Is there a PDF with the crossover design for the 4367?

    Ii's not a schematic, but here's what it looks like. Are those diodes protecting the D2340K?

    I think the diodes are for Charge Coupled the crossover.
    Have not seen drawing of the 4367 crossover, but Charge Coupled with diodes are used in other JBL filters.

    That makes sense. It also explains all the capacitor pairs.

    There should be a low pass board and a high pass board. G.T. designed them so they are definitely charge-coupled.
    The HF board is ~ $325 and the LF board is ~ $280, both unobtainable.
    The horns are ~ $390 each, also unobtainable.

    Then I'm guessing, if the photo really is for a 4367, that this is the HF board.

    That would be my guess too. The LP probably uses some pretty large inductors. My guess from that photo would be one coil for the HP filter and three LCR notch filters across the D2430K/Horn.

    Holy Cow! That's going to be one hell of a 1st listening session! Congrats on the move!!!

    I just received it tonight. I'll try and post it tomorrow.

    It is indeed charge-coupled.

    Good, I have been searching for this PDF some time now.

    Is it the same design as in 4365, not exactly off course.

    That's odd. How could a design with completely different drivers, horns and cabinets end up with the same crossover? That doesn't make sense to me. Similar sure, but identical?

    Don't know if "same" means "identical" to you, that was not what I meant.

    I was more thinking of charge-coupled.
