ADAM A7X—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.

Custom A/B 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 A7X’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 than1MHz 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.

ADAM driver technology

The A7X’s perfect integration of the X-ART tweeter with the lower frequencies is the result of a re-designed 7" mid-woofer with a much bigger voice coil (1.5") that operates in the range of 42 Hz to 2.5 kHz with a seamless transition in the crossover to the X-Art tweeter. The AX7 composite driver is driven by an amplifier with twice the power of its predecessor, which achieves a very clean and nuanced reproduction of the midrange frequencies. This configuration produces amazing sound at high pressure levels, offering distortion-free musical reproduction.

PWM custom amplifier

PWM (Pulse Width Modulation) also known as Class D amplification or switching amp technology (and mistakenly digital amplification), converts the incoming signal to a series of rectangular waveforms of equal height. The width of the rectangles varies in time and represents the musical signal. This waveform can be amplified much more simply, as the transistors are used as switches that only turn the power supply voltage on and off.

It is possible that a very fast mechanical switch could do the job, but power transistors are a better choice for the task, as such, PWM amplifiers work pretty much like conventional Class AB designs.

Advantages of PWM

The main advantage of PWM amplifiers is their extremely high efficiency (>90%). As a consequence the heat to be dissipated is only one fifth of earlier designs, leading to much lower temperatures within the amps and making the use of heat sinks unnecessary.

While PWM is highly efficient, pulse-width modulation causes signal distortion due to non-linearity of the modulation based on transient response. Usually, some form of noise-shaping filter is required to eliminate the distortion. However, that alone wasn’t good enough for ADAM engineers, who set out to develop PWM units that would perform at the leading edge of sonic quality while maintaining high efficiency. The ADAM units use a proprietary technology for both the amp and the power supply section (i.e. no more transformers) combined with state-of-the-art input and filter sections to achieve the best in multi-channel active monitoring.

Cabinet and bass reflex construction

Like the other AX-Series models, the upper and lower corners of the A77X are slanted to minimize reflections that otherwise would cause comb filtering with the direct signal. The very large, double bass reflex tubes on the front have been specifically designed to perfectly match the mid-woofer and its large voice coil.

Front- and rear-panel controls and I/O

The front panel of the A7X has a power switch and a volume control with level settings up to +14dB. Rear-panel controls include high-frequency gain (± 4dB) and two room compensation shelf EQs for high and low frequencies (±6dB). Rear-panel connections include an IEC connector with a 115V/230V switch for international use, unbalanced RCA input, and balanced XLR input.

What the pros are saying about the ADAM A7X

“Seven testers from different backgrounds have each come to the same conclusion: The review winner is the ADAM A7X!” (tools4music, Germany, 6/2010)

“I expect the ADAM A7X to dominate the conversation for a long time to come.“ (DV Magazine, UK)

“We could observe improvements in all respects.”

(amazona.de, Germany)

“...sounded noticeably better in every respect.”

(Sound On Sound, UK)

“...extremely lively and “shareful” sound with the finest high-frequency resolution.” (stereoplay, Germany)

“...I’d be tempted to choose them over anything else in a similar price range.” (FutureMusic, UK)


ADAM Sub10 MK2

The ADAM Audio Sub10 MK2 is a 200W, 10" powered subwoofer capable of extending the low end of AX-, SX-series, or any nearfield or midfield monitor system down to 25Hz

If you’ve spent any time with digital recording and mixing, which if you’re reading this, obviously you have, you’ve come to realize that with digital audio, bass is no longer the enemy as it was with analog recording and pressing vinyl (too much bass energy made needles jump out of record grooves). Coincidentally, as 5- and 6-string bass guitars became more prevalent among bassists in order to compete with the low-frequency capabilities of synthesizers, which dominated music in the ’80s, a major portion of our music migrated down to the low end of the audible spectrum. However, despite digital audio’s ability to handle greater amounts of bass, too much LF energy, particularly inaudible frequencies can eat up your headroom. Some engineers solve this problem by filtering every track, in the low end, but even with a low center frequency, filters chop off frequencies above, up into the low mids, where the body of a lot of instruments lives. All that said, wouldn’t it be nice for your mixing if you can actually hear what’s going on in the audio basement? With an ADAM Sub10 MKII you can, making mix decisions based on reality, not just cut and hope for the best. Plus, cranking the bass is a lot of fun . . .
