** Gentle-slope woofer / squawker networks **

A series of modular woofer to squawker crossover networks have been designed to operate in the Klipschorn, LaScala or Belle Klipsch along with the ES5800 extreme-slope squawker / tweeter network to allow upgrades in easy steps. Five networks are available. Each has conventional 12 dB / octave slopes. These are generally based on the Klipsch AK-3 network woofer filter which is quite good but is missing the components that equalize the "reactance slope" required to provide a constant impedance resistive load to the amplifier. Each network provides the autoformer needed to adjust the level to the squawker. Each is compatible with the 3-wire cable used by the extreme-slope networks to connect the woofer / squawker network module to the squawker / tweeter crossover module making them directly interchangeable with the ES400T, ES500T, ES600T and ES700T extreme-slope networks. A removable strap will also allow 2-way operation. Bi-wiring capability will NOT be included so as to simplify the design keeping costs down.

• AP12-AK3 set of two: $199 This network utilizes the existing woofer filter of the original Klipsch AK-3 network which is located inside the woofer hatch. It will avoid the need to open the hatch. The network will correct the improper impedance of the original AK-3 woofer filter providing a constant 6 Ohm load to the amp. The crossover remains at 350 Hz.
• AP12-350 set of two: $239 This network duplicates the Klipsch AK-3 woofer filter and provides a complete 350 Hz constant impedance crossover. This is for the Klipshorn but will work in the LaScala. It is NOT usable in the "stock" Belle Klipsch.
• AP12-500 set of two: $239 This one is intended for the Belle Klipsch or the LaScala. The crossover is at 500 Hz.
• AP12-600 set of two: $239 This one is intended for the Belle Klipsch or the LaScala using squawker drivers or horns that will not safely go down to 500 Hz. The crossover is at 600 Hz.
• AP12-700 set of two: $239 This one is intended for the Belle Klipsch or the LaScala using the Altec 811B "Voice of the Theater" horn. The crossover is at 700 Hz.
