Packed with many new design features, the KC-400 updates the previous-generation KC-350, a longtime players' favourite. The power has been increased to 150 watts, and the two-way speaker system features a newly designed 12-inch custom woofer for improved sound quality. In addition, the power section has been completely redesigned for better stability, enhanced bass reproduction, and reduced weight.
