Precision ADAM Monitoring for Home and Pro Studios

The ADAM Audio A3X is a popular nearfield monitor found in home and project studios worldwide. An active vertical 2-way design, the versatile A3X provides a balanced sound with transparent high-frequency reproduction, clear midrange, and superior transient response. The A3X's large, front-baffle bass reflex ports are precisely matched with the bass/midrange driver, giving the speaker natural, well-controlled low-end dynamics. The woofer's 25-watt PWM amplifier, in combination with the 25-watt Class AB tweeter amp, enables a pair of A3Xs to achieve a maximum SPL of 106dB at one meter. Engineered in Berlin to the strictest tolerances, ADAM's AX series monitors feature cutting-edge technology, including the company's renowned, handcrafted X-ART accelerated ribbon tweeter. With its compelling price/performance ratio and compact footprint, the A3X brings ADAM Audio's world-class monitor performance to space-challenged home and project studios on a tight budget.

4.5" carbon fiber low-frequency driver

The drivers in ADAM Audio studio monitors benefit from years of in-house research and development and take advantage of the latest advances in technology and materials science. The carbon fiber woofer in the A3X is engineered to deliver optimized low-frequency reproduction with extended dynamic range and freedom from coloration. It incorporates a rigid yet low-mass honeycomb driver cone, a highly efficient magnet assembly and precisely aligned voice coil, and an optimized driver chassis/basket design. The A3X's 4.5" woofer extends response down to 60Hz, making the speaker a superb choice for nearfield monitoring, especially when combined with a subwoofer.

The X-ART folded-ribbon tweeter

Instead of producing sound with a piston-like diaphragm like most loudspeakers, ADAM Audio's X-ART folded-ribbon tweeter uses a pleated diaphragm capable of moving air four times faster than the folds themselves are moving. Handcrafted to the tightest tolerances, the X-ART tweeter delivers ultra-low distortion and breathtaking highs up to 50kHz, enriching the soundfield with stunning detail and faithfully conveying every nuance of the source material so you can work over long periods without listening fatigue. Being handcrafted and meticulously tested in the ADAM’s Berlin laboratories, the X-ART high-frequency driver is a rare exception in these days of automated mass production.


The A3X is equipped with a Stereolink feature that provides two additional input and output jacks for the second stereo channel, allowing you to control the volume of both monitors using the volume control of only one speaker. The volume control of the second monitor only affects its own volume, for easy fine-tuning to compensate for differences in listening distance. Unlike most master/slave configurations, each A3X is fully equipped and can function either as a master or a slave unit.
