Bookshelf Speakers — KRK Systems GOAUX 4

The GoAux 4 is a powered bookshelf speaker from KRK Systems, built to run without a separate amplifier. KRK Systems has built its reputation primarily in professional studio monitoring, and the GoAux range represents the brand's move into a more compact, consumer-friendly powered speaker format drawing on that same monitoring heritage.

Position in line

It sits above the GoAux 3 and near the V4 Series 4 in KRK Systems' broader monitor range. As a numbered step up from the GoAux 3, this model likely offers a larger driver or more powerful amplifier module, following the fairly predictable scaling pattern common across most graduated speaker ranges.

Key specs that matter

Rated response is 65 Hz to 20 kHz. Internal amplification totals 100 W. At 20.5 x 13.6 x 14.0 cm and 4.3 kg it is a compact, desk-scale speaker, practical for a nearfield production or casual listening setup rather than a full room.

Sound and use context

Expect an immediate, source-integrated presentation typical of a compact active monitor, suited to a desktop rather than a full room - KRK's monitoring heritage suggests a more accurate, less consumer-voiced character than a typical lifestyle-oriented powered speaker of similar size.

Pairing

No external amplifier is used - line-level sources connect directly to the built-in amplification, keeping system complexity to a minimum.

Alternatives

The GoAux 3 sits below this model in KRK Systems' range as a smaller alternative, worth considering if desk space is at even more of a premium than this already compact model requires. KRK Systems has built decades of trust within professional recording and mixing environments specifically, and this consumer-facing powered speaker likely inherits at least some of that monitoring-derived accuracy even at its more accessible price point and compact desktop scale. A short listening comparison against a more consumer-voiced desktop speaker of similar size is worth doing to judge whether the more neutral monitoring character suits personal taste. Because KRK also sells larger studio monitors under the same broader design philosophy, comparing this compact model against one of those larger units at a dealer helps set realistic expectations for bass extension specifically. A solid, non-resonant desk surface also helps this compact monitor perform closer to its rated potential. Cable routing away from any nearby computer power supply also helps avoid picking up electrical noise in a desktop setup.
