Sonigistix today introduced the Monsoon MH-502 speaker system, an upgraded version that replaces its entry-level MH-500 system. The MH-502 is a three-piece speaker system that’s 2dB louder and offers improved imaging and high-frequency performance. The system consists of two flat-panel satellite speakers with 2.5-inch midrange cones and a small subwoofer with a 4-inch cone. The Monsoon MH-502 is available now for US$99. At press time, Sonigistix had yet to update its site with the new model.
