SW-12-16FR Servo Sub Woofer

About the SW-12-16FR Servo Sub Woofer

The GR Research SW-12-16FR Servo Sub Woofer is a 12-inch, 16-ohm servo-controlled subwoofer driver intended primarily for open-baffle, dipole, and infinite-baffle installations. It uses GR Research/Rythmik Direct Servo technology, in which a feedback coil monitors cone motion and the servo amplifier corrects the drive signal for improved control, reduced distortion, and tight bass. The driver is designed to allow multiple units to be connected to a single compatible servo amplifier; Rythmik specifies configurations of up to three SW-12-16FR drivers with suitable high-efficiency amplifier modules. It is a driver/component rather than a complete powered subwoofer, and it does not include an enclosure or amplifier. Published technical data contains some variation between GR Research and Rythmik reference pages, so values below identify the applicable source or reported range where relevant.
