    Sounds like you have 2344's which were 2 pieces. The 2344A was one piece. Those are 2342 little brother used in the 2425

    They have value. If you want to sell them let me know.

    If we knew what the hell we were doing, we wouldn't call it research would we.

    4429 verses S4700 Crossover

    David. The 4429 and the S4700 look to have the same mid and HF drivers. Horns look to be very similar. If you examine the schematics of each, it becomes obvious that the S4700 crossover is complex by comparison. The 4429, to me, is "dry" in the upper part of the midrange. My guess is, a lot more work and parts were put into the S4700 midrange crossover design. Hopefully the schematics of both get attached with this post!

    Looking at the 4429 and S-4700 schematics. The biggest change to the midrange crossover is in R4. They used a 3.0 Ohm resistor verses the 2.2 Ohm in the 4429. That change should raise the lower end of the mid horns response a little and correct the dryness in the above 3kHz response. Just turn the mid L-Pad down. I am making the assumption that the schematics are correct.

    Regards,

    John

    thanks john i did just that. sold the 4429 and upgrade my 4425.
    i am amazed by the 2416H which i thought was a sub 2426H. not at all.
    this driver is now amazing and with crossover redone with Mundorff component voices are wonderfull. this time i have to get accustomed to their new sound but i am still "at home" and have a very natural feel.
