  • The Sub-12 gets its intensity from a 12-inch, down-firing driver coupled to a highly efficient BASH amplifier that creates 300 watts of continuous power and 650 watts of dynamic power. The subwoofer?s built-in, steep-slope (24dB/octave) low-pass crossover is continuously adjustable from 40 to 120Hz. A phase control facilitates acoustical integration of the subwoofer with the other speakers in the system. An "auto power" feature enables the subwoofer to turn itself on and off (standby) automatically, based on the presence or absence of an audio signal. A blue/red dual color LED display on the front of the subwoofer indicates whether the unit is on or in standby mode.

    In addition to its ability to play louder and go deeper than anything else in its class, the Sub-12 features a new industrial design that is refined and aggressive. Available in a black finish with titanium accents, this extraordinary subwoofer matches the entire Synergy Series lineup in both style and performance.

    Because it wraps technical superiority and eye-catching cosmetics into one affordable package, the Sub-12 perfectly anchors a home theater or two-channel system.
