$450 off Klipsch Synergy Sub10 420W 10" Subwoofer

A masterpiece of sound and design, the Synergy Series Sub-10 shakes things up with its rock-solid performances. Its extraordinary power adds a dose of "reality" to movie explosions and other special effects, as well as reveals commonly elusive lower musical tones.

The Sub-10 reaches deeper and hits harder thanks to a 10-inch, down-firing driver coupled to a highly efficient BASH amplifier that creates 200 watts of continuous power and 420 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.
