The ADAM Audio A8X-SUB15 5.1 NASHVILLE BUNDLE is a 3-way, matched 5.1 surround system with a 15" SUB15 subwoofer and five 8.5" A8X active monitors featuring ADAM's proprietary X-Art ribbon tweeters.

ADAM Audio A8X

The ADAM Audio A8X 2-way monitor features ADAM’s proprietary X-ART folded ribbon tweeter and 8.5" carbon/Rohacell/glass fiber woofer, 50W/150W custom amplification, and can be used as both a nearfield or midfield monitor

The most powerful 2-way monitor in the AX range, the A8X has more to offer than just a bigger woofer. Along with the clarity, detail and wide sweet spot that all AX-series monitors have in common, the 8.5" A8X offers an affordable entry to midfield monitor—great to impress clients and get that party started. More importantly, certain styles of music such as electronica, R&B, and hip-hop require high playback levels in order to get the full effect—and that’s where the A8X shines. If you’re working in bass-heavy styles, you need a monitor that reach down really low, with clarity and power. That’s where ADAM’s proprietary 150-watt PWM (pulse-width modulation) amplifier comes in. Of course, electronic music isn’t all bass. You need a monitor that can reveal all the fine detail of reverb and modulation effects, filter sweeps, cutoff, resonance, and other high-frequency components of modern music. The A8X excels there as well, thanks to ADAM’s proprietary X-ART ribbon tweeter, which extends the A8X’s frequency range up to 50kHz. It’s the A8X’s ability to reproduce harmonics above human hearing in linear phase that has a profound effect on the audible spectrum.

ADAM Audio A8X—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 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 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 A8X’s perfect integration of the X-ART tweeter with the lower frequencies is the result of a re-designed 8.5" mid-woofer with a much bigger voice coil (1.5") that operates in the range of 38 Hz to 2.3 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 corners of the A8X 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 A8X 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 A8X

“Upgrading the already very successful A-Series was no easy task for the German manufacturer. But once again, we have to acknowledge that ADAM Audio successfully took up the challenge with this A8X monitor - the flagship of the new AX Series.” (Audiofanzine.com)

“The A8X is a powerful link between ADAM ́s AX Series and the formidable and more expensive SX Series. It's all-in-all homogenous tuning, the deep and precise bass as well as the brilliant mid- and high-frequency reproduction make this speaker a huge recommendation for ambitious people without deep pockets.” (Professional Audio, Germany)

“Even if it optically does not t into every living room, audiophiles looking for pure sound should rally to find a dealer for a demo session. These speakers tend to transform favorite songs with a hitherto unheard of clarity. The combination of the 220mm mid/low woofer and the X-ART AMT let this speaker sound powerful and detailed at the same time.” (Audio Test, Germany)

 ADAM Audio Sub15 

The ADAM Audio Sub15 is an extremely powerful, 1000-watt, 15" subwoofer capable of extending the frequency range of main and midfield monitors down to 20Hz.

If you spend a major concentration your time plumbing the depths of audio in bass-oriented music, such as hip-hop and R&B, or film post, where thunderous effects, orchestral score, and dialog have to peacefully co-exist, the powerful ADAM Sub15 gives you 1,000 watts of low-frequency extension down to 20Hz—great for large control rooms and equally large productions. The ADAM Sub15 features a sturdy 15" woofer made of an exceptionally rigid aluminum membrane. Why aluminum you ask? A 15-inch woofer has to overcome more inertia than smaller cones in order to respond quickly to transient information. The Sub15 is driven by two powerful magnets and a 4" (100 mm) voice coil. The Sub15’s inertia busting power assist comes from a highly efficient PWM (pulse-width modulation) amplifier that pumps 1000 watts (RMS) of power into the Sub15’s driver with an efficiency factor of nearly 90%. With these performance features, the Sub15 is easily capable of handling critical musical passages with intense and sudden bass peaks without showing signs of distortion or overheating.

ADAM Audio Sub15—Just the Facts:

  • 15" subwoofer (aluminum)
  • Amplifier power RMS/Music, 1000W/1200W
  • Frequency response of 20Hz-150Hz
  • Maximum SPL 120dB
  • Additional sub output enables dual sub system

Room-compensation controls and I/O

In order to adjust the sound of the Sub15 to different room situations or individual taste, the Sub15 has several controls including one for volume (-60dB to +6dB) and one for the crossover frequency (50Hz – 150Hz). The satellite speakers can either be driven full range or high-pass filtered at 85Hz. This allows the Sub15 to be easily integrated into a Dolby surround setup. Unfavorable phase relationships between the satellites and the subwoofer, particularly in the crossover frequency range, can be easily controlled with the rear-panel phase-reverse switch.

The Sub15 is also very flexible when it comes to connectivity: There are balanced (XLR) and unbalanced (RCA) Left/Right input/output connectors to be found on the rear of the subwoofer, plus an additional output enables a dual subwoofer array.
