Description

The KRK GoAux 4 portable nearfield monitors are designed to provide great sound anywhere you go. The perfect monitors for creators constantly on the move and delivering renowned KRK sound quality in a mobile-friendly size. GoAux 4 monitors come with a convenient nylon carrying bag that holds both monitors as well as the included monitor stands 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) biamplified 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.

The stands are fully adjustable, allowing you to dial in the optimum listening angl and position. A biamplified 100W amplifier powers the 4″ glass aramid woofer and the 1″ soft textile dome tweeter, which combine to provide a frequency response of 60 Hz to 20 kHz with an SPL of 102 dB. The main speaker houses the amplifier, volume control, and 2-band EQ and also provides power to the satellite. Inputs include Bluetooth, RCA, 1/4″ TRS, USB Type-B, 3.5mm, and an Auto ARC microphone connector, while a 3.5mm headphone output is provided and features an auto speaker mute for private listening sessions.

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.
