ADAM Audio A3X

The ADAM A3X is a desktop monitor with a 4.5" woofer, ADAM’s proprietary folded ribbon tweeter, and single-knob volume knob control of two speakers via Stereolink.

While it may be tempting to think of the ADAM A3X as a budget-conscious monitor, that’s just a side-effect of its intended purpose—a professional-quality monitor for desktop computer applications. Whether you’re making music on a laptop or just watching Netflix and chilling, the 4.5" A3X gives you brilliant audio quality thanks to ADAM’s precision X-ART tweeter and carbon fiber woofer. Together, these two drivers give the A3X a 60Hz to 50kHz frequency range, which is beyond that of many professional monitors. The compact A3X produces a bass response that appears to defy the laws of physics, along with a clean low-midrange devoid of the mud that lives between 200Hz-400Hz. The spatial detail and dimensionality are what you would expect from ADAM professional monitoring.

ADAM A3X—Behind the Grille

X-ART folded ribbon tweeter technology

From its inception, ADAM Audio emerged as a major force to be reckoned with in pro audio monitoring, mainly due to its innovative folded ribbon tweeter. The ribbon tweeter is based on the Air Motion Transformer concept developed by Dr. Oskar Heil, which is a pleated diaphragm similar to the shape of bellows. From the standpoint of surface area response, a 1-inch-wide pleated diaphragm is comparable in function to an 8"-diameter cone. The folded driver acts like a point-source version of a larger driver, which inherently results in lower distortion during sound reproduction. Another property of the folded diaphragm is that its squeezing movement projects air with a speed approximately five times faster than the speed of the ribbon driver itself. 

ADAM engineers took this technology and improved on it, incorporating superior geometries and materials to achieve unprecedented audio fidelity. The latest iteration of the ADAM folded ribbon tweeter is the X-ART, which explores new paths in the kinematics of moving air, resulting in a dramatic improvement in the quality of audio reproduction.

The X-ART membrane consists of a pleated diaphragm in which the folds compress or expand according to the audio signal applied to them. The result is that air is drawn in and squeezed out, like the bellows of an accordion.

The ADAM X-ART design overcomes the piston-like motion of all conventional drivers and their inevitable problems, such as narrow directivity, by achieving an improvement in air loading by a factor of 4 over conventional transducers. In addition, the X-ART tweeter’s pleated membrane avoids the typical breakup/distortion and subsequent dynamic limiting at higher frequencies found in dome and cone tweeters. Another positive result of the X-ART design is that the driving “stripes” are in direct contact with the outer air and are cooled immediately.

Diaphragm area is another important factor in determining the dynamic range of a transducer. Basically, what you see is what you get. The cone area you can see is always the acoustically active area of the loudspeaker–this is true for practically all other drive units. By folding the X-ART diaphragm into the 3rd dimension (as seen from the listener’s position) a larger foil can be used, thus increasing the acoustically effective area of the diaphragm by a factor of more than 2.5 times. This results in a higher dynamic output with extremely wide dispersion.

Class A/B custom amplifier

While the X-ART tweeter’s solved certain problems associated with conical tweeter designs, its wide bandwidth up to 50kHz, though responsible for the musicality and openness of the AX3’s high-frequency response, also created a problem in terms of amplification. PWM (pulse-width modulation) amplifiers, which have become popular due to their high power efficiency and low distortion, require a low-pass filter to separate the modulation frequency (the point where power switches from the supply rails) from the audio band. It imposes a limitation on the high-frequency reproduction of the X-ART tweeter. To preserve the wide bandwidth, which in turn preserves the phase coherency and resultant realism of audio in the audible range, ADAM put considerable time and effort into creating a high-frequency power amp to allow the high-frequency tweeter to live up to its potential.

The perfect partner for X-ART

An internal bandwidth of more than 1MHz is externally limited so that the unit delivers an ultra-wide response up to 300kHz. With nothing limiting the abilities of the X-ART tweeter, the monitor has unsurpassed clarity and openness which will daze and amaze even the most jaded professional ear.

 

Stereolink single-knob volume control

The Stereolink (A3X and A5X only) is a feature designed specifically for desktop DAW users who don’t have external monitor control systems. Stereolink, which works only with RCA inputs (not the mono XLR), comprises an input and output jack in each monitor. Connecting to Stereolink allows you to control the volume for both monitors using the volume control of one. The volume control of the slave monitor only affects its own volume to easily compensate for differences in listening distance. Each monitor can function either as a master or a slave.

Front- and rear-panel controls

The front panel of the A3X includes an on-off switch and volume control. The rear-panel inputs include balanced XLR, unbalanced RCA input as well as RCA stereo link input and output. The rear panel also has a ±4dB tweeter level control and an IEC power receptacle plus voltage selector switch (115V/230V) for international use.
