KRK GoAux 4" Portable Studio Monitor Pair

Here's what KRK have to say about the GoAux 4" Portable Studio Speakers

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. Built-in LF and HF EQ let you adjust the monitors’ response to the room and your personal preferences. With the included measurement microphone, the built-in Auto ARC automatic room correction feature can automatically optimize the response of the speakers to your acoustic environment. Along with the USB, 1/8” Aux, RCA, and 1/4” TRS balanced stereo inputs, Bluetooth capability means you can connect wirelessly to your smartphone, computer, or other Bluetooth-capable audio devices. When you need to monitor silently, you can connect to the front panel 1/8” stereo headphone output, which automatically mutes the GoAux 4 speakers.
