The woofers are a uniquely designed metal cone driver made for
the Genesis servo system. Made with a cone of solid aluminium,
the suspension and voicecoil have been maximized for long
distortion-free excursion so as to increase dynamic range. Our
aluminium cones are a magnitude stiffer than any plastic cone on
the market, 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 6,000Hz – far above the 16Hz to 120Hz
frequency range that these drivers operate at. Therefore, the driver
is a perfect piston within the frequencies used. Thus, extremely low
cone break-up distortion is inherent in the driver that is designed for
the Genesis 201.
Unlike the midrange and the tweeters, the front and rear woofers
operate in phase as a bipolar arrangement in which all sixteen
operate in unison to control the air mass of the entire room. This
means that the surface area of the eight cones and the large
enclosure all work together in unison to produce bass output that
descends evenly to below your hearing limits.
1600 watt Servo Amplifier/Crossover
One problem, however, of metal cones, is that of greater mass. To
over come this, Genesis had to build an amplification system of
great wattage, and high damping factor. 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 201, the amplifier was designed as a holistic system
of integrated connecting cables, woofers, and custom tailored EQ
network and remote controlled crossover circuitry. The proprietary
four-channel 400 watt per channel switching amplifier is specifically
designed and tuned specifically for low frequencies in order to
produce “floorshakingly 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 201. No longer must one choose between having an
amplifier with enough power to drive the woofers, and a smaller
