The KRK GoAux 4 portable nearfield monitors are designed to provide great sound anywhere you go. The perfect monitors for traveling musicians and engineers, they deliver renowned KRK sound quality in a mobile-friendly size.

Since they're made to go wherever you do, the GoAux 4 monitors come with a convenient nylon carrying bag that holds both monitors as well as the included monitor stands, Auto ARC microphone, and any extra cables you want to take along with you. The stands are adjustable for the optimum monitoring positioning and angle.

The GoAux 4 monitors pair a 4" glass aramid woofer with a 1" soft textile dome tweeter in a 100 W RMS (total system power) bi-amplified two-way design. The rear-ported ABS cabinets are durable and supply surprising bass extension for a portable speaker. With the power amps located in one speaker's housing and the second speaker powered through an included speaker-level connection from the first, the pair only needs a single AC outlet for operation
