In this photo from Bonobo's studio, an ADAM A7X can be spotted just right-of-center of the shot. The yellow rectangular grate on top distinguishes it as an ADAM model of monitor. It must be an A7X, as there are screw holes on the horizontal edges, whereas on the A8X they point vertically.more
Jaytech's primary studio monitors are the ADAM Audio A7X. They can be seen in this photo of his Berlin studio gear setup which he posted to his blog. He uses the ADAMs alongside a pair of KRK VXT 6. "At the moment I’m rocking some Adam A7X monitors alongside some [KRK VXT 6](http://equipboard.com/items/krk-vxt6-active-studio-monitor). Also hooked up in the corner is a single [Alesis M1 Active Mk2](http://equipboard.com/items/alesis-m1-active-mk2-bi-amplified-studio-monitor) (my first ever monitor speakers) for mono/bass reference. Three different kinds of speakers with three different characters of sound, and you can discern these characteristics largely just by looking at them. The A7X come in a sleek, black wooden cabinet and have a soft, detailed sound with a stereo image that lets you really listen into the music and hear what you need to hear. They are well suited to modern styles of production. ...your best bet is to have a few options, and get into a habit of switching to these different systems to get only what you need from them. I’ll mix for three hours on the A7X and then come back to the KRKs for 30 minutes, to bring some fun back in the mix when it’s sounding quite clinical."

"Yo, before I picked these up I didn't know for sure what my mix truly sounded like. Sometimes too dark and other times too bright. Between the two, all I can say is now I don’t have that problem anymore. Your mix is only as good as the monitors you use."

The evolution of a legendary near-field monitor.
More than 30 glowing reviews, numerous awards, and countless dedicated fans made the A7, the predecessor of this new model, a true legend in near-field monitoring. Now, the legend continues with the A7X: All drivers, all amplifiers, as well as the cabinet have been revised, resulting in a speaker that claims nothing less but to be a new benchmark in near-field monitoring.
The first aspect that distinguishes the old from the new model is the X-ART tweeter. The ˜X™ stands for ˜eXtended frequency response™ and thus for one of the features of the Accelerating Ribbon Technology that has been drastically improved: the frequency response. It now extends all the way up to 50kHz. In addition, the X-ART tweeter has a higher efficiency and higher maximum sound pressure levels.
The perfect integration with the lower frequencies has been achieved with a newly designed 7 midwoofer. It has been redesigned with a much bigger voice coil (1.5) and is driven by an amplifier with twice the power compared to its predecessor. This combination produces an amazing sound and pressure levels with an almost distortion-free musical reproduction.
Amplifiers / controls
Each driver has its own dedicated amplifier. A 50W A/B amp is responsible for the X-ART tweeter, while the midwoofer is being driven by a 100W PWM (Pulse Width Modulation) amp. The front panel includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.
On the rear panel of the A7X are several additional controls: a gain for the high frequencies (± 4dB) and two shelf filters for high and low frequencies. To ensure greater compatibility, there are both XLR (balanced) and RCA (unbalanced) connectors.
The X-ART (eXtended Accelerating Ribbon Technology) tweeters and midranges incorporate a new approach to the Air Motion Transformer concept originally developed by Dr. Oskar Heil. ADAM Audio has improved upon this splendid idea utilizing superior geometries and materials to achieve unprecedented audio fidelity. X-ART strikes a new path concerning 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 by achieving an improvement in air loading by a factor of 4 over conventional transducers. To illustrate the basic principle by a comparison: When you breathe, your thorax is moving slowly whereas the air is moving comparably fast. Similarly, the X-ART diaphragm presses the air faster in or out of its folds than they themselves are moving. This markedly superior motor is responsible for the unprecedented clarity and pristine transient reproduction that can be heard with the ADAM X-ART drive units.
In addition, the X-ART tweeter' pleated membrane avoids the typical breakup/distortion and subsequent dynamic limiting at higher frequencies of stiffer voice coil designs, such as those 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.
Pulse Width Modulation
PWM (Pulse Width Modulation) “ sometimes referred to as Class D amplification, sometimes called Switching Amp Technology “ converts the incoming signal to a series of rectangular waveforms of equal height. The width of the rectangles varies in time and the relation of the width of the rectangles represents the musical signal. This waveform can be amplified much more simply, as the transistors are not modulated anymore; instead they 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, so PWM amplifiers still work pretty much like conventional Class AB designs. It is important to note there are no bits and bytes involved, so œDigital Amplifier is a misleading and inaccurate term.
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 obsolete.
This principle has been known for decades, but time was needed to develop units that perform at the leading edge in sonic reproduction quality and yet still maintain the high efficiency mentioned previously. The ADAM units use the new 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 studio monitoring.
I really really love them !! They show u the truth about your sound !! sometimes it can be sad how accurate they are and u can notice how u sucked before :D !! cheers ! (bought them in 2000$ !!! worth any peny) !
These speakers are basically surgical, so if thats your thing then great, i find these monitors are brilliant very accurate with a good high end they are also not very taxing to listen to for long periods of time. Mixes also transfer very well.
these monitors offer an excellent range of frequencies that i would imagine suitable for any genre of music, i use it for rock/metal, they allow the mixer to pop out guitars or vocals very easily as the clarity is of great value for money, highly recommended!
Definitely not going to be able to afford these for a long time. If and when I get my own space for a studio, and have money spare, I might treat myself to these. But at the moment my M50s are fine for monitoring, and I like my portable setup without studio monitors.
