ESCO 90x118x150mm high power speaker USB power supply

Closed full-range speaker system A wooden cabinet designed for superior sound quality reproduces beautiful and pleasant sound.
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 (PowerReserving Amplifier Circuit)" circuit that enables high output when necessary by charging power in the capacitor.
In order to strengthen the bass range, which is the weak point of small 2-channel speakers, a passive radiator unit is installed on the back of the main unit. By installing it parallel to the speaker unit, it efficiently resonates the bass range and enables rich bass reproduction.
Built-in USB DAC allows high-quality sound data from your computer to be sent to the speakers as digital data, and converted to analog within the speakers with less noise, allowing you to reproduce clear, high-quality sound sources.
Since the power ON/OFF switch and volume control switch are installed independently, you can immediately enjoy the music at the usual volume just by turning on the power.
