Sanwa Supply USB Speaker High-Power (Black) MM-SPU9BKN

This USB speaker uses a single USB cable to supply both power and audio. Because it only requires one USB cable, it allows for a clean and organized setup around your computer. To achieve the surprisingly high output that conventional USB speakers cannot produce, it is equipped with a large capacitor inside. It features a "PRAC (Power Reserving Amplifier Circuit)" that enables high output when needed by charging power within the capacitor. To enhance the bass response, which is a weakness of small 2-channel speakers, a passive radiator unit is mounted on the back of the unit. By positioning it parallel to the speaker unit, it efficiently resonates the bass frequencies, enabling rich bass reproduction. To pursue a beautifully resonant sound quality, we use a high-density MDF wooden cabinet. This reproduces a beautiful and pleasant sound resonance that is difficult to achieve with resin cabinets.
