** Gentle-slope woofer / squawker networks **

A series of modular woofer to squawker crossover networks has 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. This network will also operate in the Cornwall or Cornwall II
• 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.

** Gentle-slope squawker / tweeter networks **

The AP15-xxxx series is proposed. It will be the same design as the high frequency section of the Universal network. It will be 18 dB / Octave on the tweeter and 12 dB / octave to the squawker, will include the transformer tweeter attenuator and will be a gentle-slope alternative to the ES5800. The price will be $299.00 for the 6000 Hz version. When paired with the economy AP12 series woofer / squawker crossover the total cost will be roughly the same as the Universal network and should outperform it. The trade-off with the Universal will be the slightly higher quality components in the simpler (6 dB / octave) woofer / squawker filter used in the Universal compared to the flexibility of compatibility with the extreme-slope designs and the ability to attenuate the tweeter if necessary.

These are available for 6000 Hz and 4000 Hz crossover. The 4000 Hz version should not be used with the stock K77 tweeter. The Crites CT125 or better is suggested.

A version having the correct transformer connected to attenuate the sqwuawker in a bi-amp configuration is also available. It will be desingated the AP15-6000T.

These are available now.
