Servo Sub kit 2

The Servo Sub kit 2

This package comes with a single SW-12-04 servo woofer and the A370PEQ amp  
This design is for sealed box applications using 1.5 to 1.8 cubic feet of air space. This combination is the pinnacle of low frequency reproduction. The quality level of bass reproduction using this servo control system exceeds any other woofer and amp combination available by any company at any price. The A370PEQ amp has all the key features necessary to allow easy blending to main speakers, and enough additional features to allow it to do anything you want. Low frequency extension is adjustable. The damping settings are adjustable. It even adds a rumble filter that can be turned on when playing vinyl. And with 370 watts of power it can deliver solid SPL levels that reach down into the teens.

Lining the cabinet walls with No Rez really helps minimize cabinet resonances and provides a cleaner and smoother sound. A sealed box cabinet will require 1 sheet. 

Currently only the A370PEQ3 and A370XRL3 amps are the only amps available. These models have a limiter setting that reduces overload of subwoofer arisen from large signal surge and is recommended for HT. They are $40 more than the standard amps.
