    2344

    I was looking at the Humble Hifi site and noted a project that seems to use a JBl 2344 with a 12-15 inch woofer… attractive looking speaker …take a look.

    4312A clones

    Are you going to use a crossover similar to the original or something like the 4412?

    4312 refurbishment

    I’d bet that a 4412 crossover with 4312 drivers would go pretty well together.
  5. 12 inch woofer + horn tweeter

    I have access to a pair of 123a woofers and have contemplated a similar project. My thought was to use the crossover form the L 200t3 as a basis. That would require the 2426/ 2342 combo or similar....

    4312 Crossover

    I think you will need to consider whether you want a more accurate monitor(4412)versus old style fun monitor(4312). IMHO I would go for a 4412 crossover or an Alpha S70 as opposed to the old 4312...

    Heil with a JBL woofer

    Anyone ever copy/replicate the crossover Dennis Murphy for a custom pair of Salk speakers?
    I believe it was at about 1600 hz.

    Would recommend looking at the Jubal/ l65 crossover as a potential candidate but I would punt the le-5 for a 104h-2.

    I wonder how the Heil would respond in a sealed midrange style enclosure ? ESS used to make a model 1B Bookshelf that looks interesting.

    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...

    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.

    I have an old black pair of 123a woofers from an early L-88 and have looked at using the S70 Alpha III crossover design but would like to alter the midrange high pass from 7000hz down to 3500hz. Any...
