◆ Powder Coat Finish
Powder coating has long been the industry standard for durability in
protective metal finishes. A dry powder (non-aerosol) is electrostati-
cally applied to the metal and “baked” on to provide a hard “shell-
like” finish. As an additional benefit, powder coating is the only
finishing process that releases no toxic chemicals into our ozone.
THE RESULT: A durable and “earth friendly” metal finish.
Crossover Features
◆ Optical Compression Circuit
The speaker's linear compliance is balanced through the use of a
“proprietary” flat spider design. A flat spider provides symmetrical
control of the voice coil through its cone excursion. Linear cone
excursion reduces harmonic distortion for improved sound quality.
THE RESULT: Reduces mechanical distortion for better sound quality
.
◆ Series Notch Filter
The Series Notch Filter compensates for the inductive load presented
by the driver (speaker). The filter's primary function is to dampen and
eliminate the effect that driver resonance has on the crossover. The
Series Notch Filter flattens out the inductive load which greatly
improves driver performance by providing a “stable” crossover point.
THE RESULT: Improves driver performance by reducing resonant
peak.
