** Extreme-slope crossover networks **

Extreme-slope networks separate the sound into frequency bands appropriate to each of the drivers (woofer, squawker or tweeter) and sends them ONLY to that driver. There is only a very small overlap where two drivers are sounding together and can interact with each other. Eliminating driver interaction eliminates the need for "time alignment" resulting in a much wider sweet spot, a noticeably better stereo image and a smoother frequency response throughout the room.

An article describing crossover networks similar to those shown below having slopes on the order of 120 dB / octave in a Belle Klipsch can be viewed here. The article explains their benefits which are improved stereo imaging and a widening of the sweet-spot. The article also investigates such factors as filter ringing, group delay, driver interaction and time alignment. The artice is hosted by Klipschcorner.com

Take a peek at some installations of the extreme-slope networks

The networks in a Belle Klipsch with an Altec 811b squawker horn+JBL driver and a Beyma CP25 tweeter. These are early versions of the ES700 and the ES7500T.

This a newer installation in the same speaker. It uses the ES500T and ES5800 with Trachorn 400 and the same drivers.
