    4312SE crossover schematic

    I am looking for this schematic as I would like to try it on some older 4311 series for comparison purposes. I may ultimately try a Fountek ribbon tweeter as a replacement for the tweeter.

    Might the 4312B Mk-II be close enough to work for you?

    Or maybe this 4312SX which shows the Audax tweeter?

    Thank you for the information...what intrigues me is the 640hz crossover from woofer-midrange. I have also thought about using the 4319 woofer-midrange and the the 4412 midrange- tweeter as a possibility.
