momentum of the cone makes it continue to move after the signal has
stopped.
momentum of the cone makes it continue to move after the signal has
stopped.
The sonic result is overhang, bloat, lack of tautness and definition, and
a blurring of dynamic impact. With the servo system, the circuit senses
that the woofer is not moving as fast as it should, and it
instantaneously applies much more current to make it move faster.
When the signal stops, it predicts that the woofer will continue to move
when it shouldn’t, and applies a counter-signal to stop the woofer
faster and more effectively than an open-loop system could possibly
respond.

Thus, servo-bass systems reduce distortion and improve transient
response by making the woofer seem mass-less. Typical non-servo
woofer systems have distortion levels that exceed 10% at even
moderate levels. The Genesis servo-bass system reduces this
distortion to below one percent at almost any output level. The system
also drives the woofer to constant acceleration, which makes the
frequency response of the woofer anechoically flat to the lowest
frequencies.

4.5 The Woofer Tower
Six 12” woofers mounted in a 7½ foot tall tower 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.

The woofers used in a servo system must be strong enough to
withstand the high-current approach of the servo amplifier, and yet
delicate and light enough to react extremely quickly. The Genesis 1.1
features a total of six front-firing 12-inch woofers per channel, each
with its own accelerometer, enclosure chamber, and servo amplifier.

While the servo system is able to ensure that the driver works linearly
as a perfect piston, it is unable to correct for distortion caused by cone
wobble, bending, and break-up. Hence, the drivers were designed to
minimize these non-linear distortions, allowing the servo system to
achieve maximum accuracy.

The woofers are a uniquely designed metal-cone driver made for the
Genesis servo system. Made of a cone of solid aluminum, the
suspension and voice-coil have been maximized for long, distortion-
free excursion so as to increase dynamic range. Our aluminum cones
