Tweete

Wave Guide

The wave guide is a proprietary axis-symmetrical form of horn mounted to the tweeter to increase efficiency. The wave guide improves the transition of sound waves (from planar to spherical) smoothly from the throat of the wave guide to the mouth. The unique shape and smooth surfaces improve the tweeter's off-axis frequency response as well as provide coherent on-axis response.

THE RESULT: Improves dispersion for a wider “sweet spot.”

Woofer

Shielded Magnet

A shielded magnet is used to reduce the radiation of high-strength magnetic fields from the woofer's motor assem- bly. Suppression is accomplished by attaching a “bucking” magnet to the motor assembly in order to keep stray leakage flux within the monitor cabinet. This type of shielding prevents color and image distortion when placing the woofer in close proximity to

direct view (CRT) television receivers and computer monitors.

THE RESULT: Prevents distortion in TV and computer monitors.

Cabine

Phase Coherent

Each monitor is Phase Coherent in order to assure proper arrival times of all frequencies in the near field environ- ment. This is accomplished by aligning both transducer's voice coils on a common ZDP (Zero Delay Plane) axis. The cabinet baffle positions the woofer forward and the waveguide displaces the tweeter back with an additional 39ms delay in the high frequency amplifier to precisely “tweak” the tweeter onto its ZDP axis. This allows the acoustic center, located midway between the high and low frequency transducers, to coherently deliver a flat fre- quency and phase response around the crossover point.

THE RESULT: Delivers a flat frequency and phase response.
