Our crossover design and component parts are also unique in the industry. Crossovers separate the original signal from the amplifier into different groups of specific frequencies. Many speaker companies use a 2nd order crossover (12db/Octave) to send the treble sounds to the tweeter and the bass sounds to the woofer. Choosing an example of a crossover frequency, at 500Hz, the signal to the woofer will be reduced by 12db when the signal reaches 1000Hz, allowing some of the sound energy at 1Khz to emanate from the woofer. This residual energy may cause problems, if your woofer is not designed to play sounds above 500Hz. Therefore, the larger the reduction produced by the crossover, the better.
Our design uses a 4th order (24db/Octave), meaning that over an octave you will receive a much higher reduction in unwanted sound frequencies going to the wrong driver. The difference between a 2nd order crossover and a 4th order crossover is remarkable, as the 2nd order will produce 1/16 of the signal energy at one octave, while a 24db/octave slope produces a signal that is only 1/256 as loud, quite a substantial difference.
Our crossover parts are also extraordinary. Nearly all our competitors use magnetic core inductors or at best, air-core copper wire wound inductors. Both types of inductors create audible distortion. At High Desert Audio, we use Bridgeport Mechanics 12-gauge pure copper foil inductors, eliminating any hysteresis or distortion in the coil. Further, we use the MultiCap™ film and foil caps along with Audiocap™, ensuring a smooth pure sound with no coloration from the caps. All internal wiring is 99.99999% pure copper plated with 85 microns of silver, that has a Teflon spacer around each of the conductors inside an extruded Teflon tube.
