Madisound is pleased bring you our SB12SUB ~ SB Acoustics 12” Powered Subwoofer Kit.

This acoustic suspension (sealed box) design combines the SB Acoustics 12” woofer, our Keiga 300 watt amp, and a high quality furniture grade cabinet in an easy to build subwoofer kit. Everything you need to construct a finished subwoofer is included.

Our goal as always is to provide the highest quality bass reproduction for your hi-fi stereo system. In the SB12SUB, this is achieved with a well designed woofer powered by class A/B amplification and mounted in a rigid sealed enclosure. 

Blending this subwoofer into your system is easy. Seamless integration with your speakers is achieved by the fully adjustable level and crossover controls on the KG5230 amplifier. The built in active 12db/octave crossover can be set between 50Hz – 100Hz to perfectly match the low end roll off of your main speakers. The active crossover can be turned off if you choose to use the subwoofer/LFE output on your processor/receiver.
