The KRK GoAux 3 portable monitor system is designed for on-the-go audio professionals and content creators who require accurate sound reproduction in a compact form factor. These three-inch active monitors deliver a balanced frequency response suitable for critical listening, mixing, and editing in mobile or space-constrained environments. The system includes two satellite speakers and a subwoofer that collectively provide a full-range sound experience rarely found in such a portable package. Constructed with a durable ABS enclosure, the GoAux 3 monitors resist wear from frequent transport and setup.

Each satellite houses a custom 3-inch woven glass-aramid composite woofer and a 1-inch soft-dome tweeter, driven by class-D amplification that ensures efficient power usage without compromising clarity. Frequency response extends from 40 Hz to 22 kHz, enabling users to hear low-end detail and high-frequency nuances. The subwoofer incorporates a 5.25-inch driver to reinforce the lower registers, delivering punchy bass reproduction for mixing electronic music, film audio, or podcast production.

Connectivity options include balanced TRS and unbalanced RCA inputs, along with a stereo aux input for mobile devices. The front-facing control panel offers volume, low-frequency EQ, and high-frequency EQ adjustments, allowing customization to suit different acoustic environments. The system also features a headphone output for private monitoring.

The monitors are powered via an included external power supply, and their total weight under 10 pounds makes them one of the lightest full-range monitoring solutions available. Built-in protection circuitry safeguards against overheating, overcurrent, and short circuits, ensuring reliable operation during extended sessions. The enclosure is designed with a low-resonance structure to minimize unwanted coloration, while the front-firing bass port allows placement near walls without excessive bass buildup.

This makes the KRK GoAux 3 system a practical choice for temporary studios, hotel rooms, dormitories, and small home setups where space and acoustics are challenging. Priced at an accessible level, the KRK GoAux 3 delivers a combination of portability, build quality, and accuracy that suits budget‑conscious users who do not want to compromise on monitoring quality. While not a substitute for larger studio monitors in dedicated rooms, this system ably serves mobile mixing, voice‑over work, and casual listening with a clean, detailed sound signature that reflects KRK’s engineering heritage.
