From the Manufacturer

USB speaker equipped with "PRAC circuit" which can output up to 25.6 W with a single USB cable.


High power but easy to connect with a single USB.No power supply required Built-in USB DAC transmits high quality data inside your computer digitally to the speaker. Analog converts within the speaker with low noise effect for clear sound source.	Equipped with passive radiator unit for significantly enhanced bass range Equipped with a passive radiator unit to enhance the bass that is the weak point of a small 2ch speaker. It is placed parallel to the speaker unit, so you can efficiently resonate bass and play rich bass.	Wooden cabinet for superior sound quality High density MDF wood cabinet for beautiful sound quality.Reproduces a beautiful and comfortable sound that is difficult to use with resin cabinets.	Equipped with a "PRAC circuit" that allows you to power your speaker with less power in USB buses. Equipped with "PRAC (Power Reserving Amplifier Circuit" circuit".When the sound is small and does not require too much power, the excess power is stored in the capacitor, and when it produces a loud sound that requires high output, discharge the stored electricity and allow for high power output.Equipped with a PRAC circuit that looks like a hybrid car.
