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

This is a USB speaker that supplies power and sound source with a single USB cable. The connection cable is just one USB, so you can connect around your computer neatly. A large capacitor is installed inside to achieve surprisingly high output that cannot be output with conventional USB speakers. Equipped with a "PRAC (Power Reserving Amplifier Circuit)" circuit that enables high output when necessary by charging power in the capacitor. A passive radiator unit is installed on the back of the main unit to strengthen the bass range, which is the weak point of small 2-channel speakers. By installing it parallel to the speaker unit, it efficiently resonates the bass range and enables rich bass reproduction. A high-density MDF wooden cabinet is used to pursue beautiful sound quality. It reproduces the beautiful and pleasant sound reverberations that are difficult to reproduce with resin cabinets.
