The Reference 3 S.A. (subwoofer amplifier) is our 2 x 240 watt stereo amplifier which incorporates an active crossover/bass EQ option to extend the Nucleus Reference 3's bass response to a room-shaking 22Hz by driving the woofers' second voice coil directly. The combination of the Reference 3 loudspeaker and the S.A. subwoofer amplifier takes this home stereo speaker's unparalleled sound yet another step further, maximizing full-range performance with true stereo subwoofer bass extension from a small, unobtrusive package.
With the amp, crossover and phase controls in one unit this can be used on any speaker for true biamping. Has many connection options including high level and low level.
