10. 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 The Woofer Tower Six 12 woofers mounted in a 7 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 cause
