Servo Sealed Plus Kit (Single)

$898.00 Single

120V-60Hz regions only
Due to incompatibilities with 240V mains power, we can no longer offer these amplifiers for much of the global market.


This package comes with a single SW-12-04 servo woofer and the A370PEQ amp. The A370PEQ amp as a lot of features and flexibility that allows this system to do anything. Damping can be adjusted as well as the low end extension. There is even a one band EQ that allows adjust-ability of a narrow or wide band. Complete control over phase makes blending to main speakers easy as well. ​This design is for sealed box applications using 1.5 to 1.8 cubic feet of air space.
