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.

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.

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. DR BILL+
