Page 15: Active Servo Technology
ACTIVE SERVO TECHNOLOGY The theory of Active Servo Technology is based upon two major factors, the Helmholtz resonator and negative- impedance drive. Active Servo Processing speakers reproduce the bass frequencies through an “air woofer”, which is a port or opening in the speaker’s cabinet. This opening is used instead of, and performs the functions of, a woofer in a conventionally designed speaker system. -
