Designed for class-leading, room-filling low-frequency performance, the RSW-12 is sonically, cosmetically and technologically matched to the Klipsch Reference Series of speakers. The RSW-12 has a rear-firing active driver and a front-mounted passive radiator, both with 12-inch cerametallic cones and rigid, low-resonance cast-aluminum frames. The active driver's large magnet structure and high-temperature voice coil enable it to deliver rich, clean, thunderous bass down to the bottom of the audible frequency range without sacrificing clarity and detail.
It's powered by a high-efficiency BASH digital hybrid amplifier, capable of 2400 watts dynamic power output (FTC-rated for 625 watts). The passive radiator enables the RSW-12 to generate high levels of very deep bass. To ensure seamless blending with a system's main speakers, the RSW-12 incorporates an exceptionally steep 36dB/octave low-pass electronic crossover with a continuously variable frequency control and a phase switch. A bypass switch allows direct connection to the subwoofer amplifier for use with the crossover built into an A/V preamp or receiver.
It has low-level inputs that also operate as an LFE input (for compatibility with 5.1 digital sound formats) and an adjustable low-pass crossover that allow you to configure the subwoofer to your room's acoustics. The easy-to-reach, side-mounted volume control makes for simple setup and convenient level adjustments between music and movie sources. An auto-power feature enables the subwoofers to turn on and off automatically.
What Is Dynamic Power?
Dynamic power indicates the actual power this amplifier will deliver to the woofer under normal operating conditions. While the FTC power rating indicates power available on a continuous, long-term basis, subwoofers do not rely on that type of power. Instead, the amplifier is called upon to deliver large, short-term peaks of power to be able to support the wide dynamics required by today's digital music and movie formats.
Product Description
The RSW12 powered subwoofer extends and intensifies low-frequency output in any audio system. Whether providing all the bass for a system built around small satellites or filling in and reinforcing the bottom end for full-range speakers, it dramatically enhances sonic impact and emotional intensity.
