Sold individually, the black G One Active Two-Way Speaker from Genelec is designed to deliver powerful, self-amplified sound. The two-way G One features a 12W amplifier for its 3/4" tweeter, and a 12W amplifier for its 3" woofer. Bass response is expanded thanks to the speaker's rear-facing reflex port.

Rear-mounted adjustable tone controls allow you to customize the sound of the speaker based on the speaker's location in your listening environment, such as placement near a wall or corner.
