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.  
4.6 Servo-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. 
4.7 The 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.
