ADAM Audio A3X

Particularly interesting for the quality-conscious user on a tight budget is the most compact monitor of the AX-Series, the A3X. Specially designed for studio environments with limited space, the A3X easily meets professional requirements. Three-dimensional spatial representation, a controlled, deep bass response and accurate sound reproduction, especially in the critical areas between 200 and 400 Hz, make it the first choice for smaller, even mobile studio setups.

With the A3X, analytical listening is possible without taking away musical enjoyment. Its excellent transient response and ability to easily play very dynamic tracks in all musical genres let it clearly stand out from comparable monitors in this price range.


The ‘Stereolink’ is a useful feature for desktop DAWs. Two additional input and output jacks for the second stereo channel allow you to control the volume for both monitors using the volume control of only one loudspeaker. The volume control of the other monitor only affects its own volume in order to easily compensate for differences in listening distance. Unlike the typical master-slave configuration, each A3X monitor is fully equipped and can function either as a master or a slave unit.

In a small to medium size setup, it will be an excellent main monitor. In a larger setup, it will be an excellent alternative to bigger speakers, providing accurate near-field information, and offering relief from ear fatigue that a large system can inflict.

Lorenz Rychner
Recording Magazine (US)

For mobile setups or studios with limited budgets for monitors, the ADAM A3X is an excellent new option.

Steve Silverstein

Although they are small, the size of the audio image belies their size. The overall feel is effortless and solid, with a suprising degree of weight in the bass end.

Huw Price

The low-frequency response is very powerful, considering their size, and the X-ART tweeter produces a very detailed sound. (…) The ADAM A3X is without a doubt the best compact speaker in this price range.

Red Led

I’ve used various monitors for my computer work before, but never of the caliber of the A3X series. Before these, I would have to redo my mixes significantly when transitioning from the small cheapies to the big ‚real ones‘. The ADAM Audio A3X’s save me a step by providing both great sound in a compact format and by changing mundane audio task-work into a quality listening experience. (…) Highly recommended.
