Servo-controlled Bass Amplifier

One problem, however, of metal cones, is that of greater mass – even ones as light as the ones used by Genesis. To over come this, we had to build an amplification system of great power, 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. This means that the amplifier used must efficiently deliver extraordinarily large amounts of clean power into low impedances.

The servo-controlled bass amplifier was designed as a holistic system of woofers, integrated connecting cables, amplifiers, servo- control and remote controlled crossover circuitry. Two separate two-channel amplifier modules are used for the left and right woofer towers.

Specially designed and tuned Dynamic Power Delivery System (DPDS) power supplies are used – one for two channels – to deliver balanced dynamics which are critical to bass accuracy. This improves the power factor of the power supply in delivering the bass frequencies, resulting in “floorshakingly musical” bass to power the servo woofers.

A further advantage to separating the amplifier modules of the left and right woofer towers is that if you are lucky enough to have multiple 20amp circuits in your listening room, you can power each woofer tower from a separate circuit. This allows for even better transient bass dynamics. The Maximum Dynamic Headroom Reservoir (from the Genesis Reference Amplifier) is also available as an upgrade to Servo-Controlled Bass Amplifier, which will give even faster bass transients, and better macro- and micro- dynamics.

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 2.2. 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 midrange/tweeter sections.
