DRBILL Posted December 5, 2002 Share Posted December 5, 2002 This is my second try. I hope for luck! I have obtained a K-ORTHO DRIVE balancing network (crossover) K-1000/6/5000. Can anyone tell me from which Klipschorn model this came? The date is 7 January 1957. It is mounted on a trapezoid-shaped plywood base. The input is identified as 16Ù. What impedance would the three outputs like to "see"? I have in mind a center channel for my Klipschorns. I have a c.1970 Klipsch tweeter and a ten-cell Altec horn with a 15Ù 802-B driver. I haven't thought ahead to the woofer, but I would expect to build something. Any information and suggestions would be appreciated, especially about the crossover.

Malcolm Posted December 5, 2002 Share Posted December 5, 2002 Klipschorn, shorthorn, maybe early Heresy? Whichever, this crossover was used University SA-HF squawker driver, and 4401 tweeter. IIRC impeance was 16 ohms and 8 ohms respectively. Woofer would probably have been a 15" Stephens 103-LX-2 or EV 15WK, or 12" EV 12WK, all with 16 ohm nominal impedance. The EV units, and I believe the Stephens unit, were special versions of the standard product for use as horn drivers. The EV units have 3.2 ohm DCR resistance.

JohnA Posted December 5, 2002 Share Posted December 5, 2002 The designation K-1000/6/5000 is odd and I've never seen that except maybe on ebay recently. It did NOT come from a Klipschorn. The Klipschorn's crossover points have been 500 and 5000 or 400 and 6000 until this year when they became 400 and 4500. The 1957 K-horn crossover should have been a K-Ortho K-500/5000. I'll bet the one you have came from a Shorthorn or Rebel. The impedance of all of the drivers were most likely 16 ohms for the crossover to carry a 16 ohm label.

Shorthorn or Rebel. One of the links you suggested showed the exact item, trapezoid shape, schematic, and all. Many thanks for you knowledge and interest in my problem. I was Paul's priest at St. Mark's Episcopal, Hope, in the late '60's. I spent many happy hours loitering around his lab out at the Proving Grounds.
