A master in performance, the Reference Series RT-10d Digitally Controlled Subwoofer (DCS™) will shatter your expectations for deep, driving bass. With its superior technology and rock-solid construction, this powerhouse adds a dose of "reality" to explosions and other special effects.Featuring a triangular-shaped, small footprint design, the RT-10d employs three ultra high-output 10-inch Cerametallic™ drivers (one front-firing woofer, two rear-firing passive radiators) and a potent 700-watt RMS amplifier. Fitting nicely into a corner, the RT-10d's unique enclosure style allows the passive radiators to face both corners of the wall for maximum output. Through proprietary DCS technology, this subwoofer gives you more control and flexibility with different source material. The DCS digital user-interface offers quick and easy adjustment of all functions, including three equalization modes (flat, depth and punch) and five user-adjustable presets (music, movie, night and two name-your-own settings) to create specific listening preferences. By utilizing a patent-pending auto room correction process, formally known as Adaptive Room Correction™ or ARC, and the included calibration microphone, the RT-10d ensures ideal performance in every listening area at the touch of a button. It also comes with an IR sensor for operation from any learning remote or control system. Meticulously crafted in a cherry or black wood veneer finish, the RT-10d has an elegance and style that perfectly anchors your home theater or two-channel stereo music system.
