are a magnitude stiffer than plastic or paper cones, and virtually eliminate the problems caused by cone bending and break-up.
The lowest break-up mode (where there can be any chance of distortion at all), is at 3,600Hz – far above the 16Hz to 140Hz frequency range at which these woofers operate. Therefore, the driver is a perfect piston within the frequencies used.
4.6Servo-controlled Amplifier/Crossover
While the advantages of metal cones include extreme stiffness resulting in very low distortion and break-up, one problem is that of greater mass. The servo system also places extraordinary demands on the amplifier because the system uses enormous amounts of current to make the woofer follow the input signal. Combined with the metal cones, this means that the amplifier used must deliver extraordinarily large amounts of clean power.
In the Genesis 1.1, the amplifier was designed as a holistic system of integrated connecting cables, woofers, custom tailored EQ network and remote controlled crossover circuitry. The proprietary six-channel 500 watt per channel amplifier is specifically designed and tuned especially for low frequencies in order to produce floor-shaking, musical bass to power the servo woofers.
One side benefit of this powered woofer system is that almost any sized amplifier can be used to drive the mid/tweeter section of the Genesis 1.1. No longer must one choose between having an amplifier with enough power to drive the woofers, and a smaller amplifier having better spatial and tonal characters. Nevertheless, we do recommend no less than 100 watts as a minimum for the mid/tweeter sections.
4.7The Crossover
If the servo-controlled bass amplifier is the pulsating heart of the Genesis 1.1, the crossover is the brain. In order to manage and maximize the performance of the extensive complement of transducers used in the Genesis 1.1, we’ve designed a hand soldered direct wired crossover utilizing the finest components available as well as several custom designed elements. This includes the first multiple- tapped copper film air-core inductor.
