The CMS 50 is the most compact monitoring loudspeaker of all the Focal Professional range. Its design permits listening from 50cm away, while still keeping the possibility of the monitors at a great distance from one another without damaging the soundstage. The 5” mid-woofer reaches down to 55Hz, while offering a controlled bass and a totally linear midrange. The midrange register of the CMS 50 has unequalled neutrality in its price range. The Al-Mg inverted dome tweeter offers outstanding dynamics and a degree of definition in the treble that allow precise measurement of reverb and other effects which are normally very difficult to assess.

DM-2100: 2.1-ch Speaker System Features The DM-2100 2.1-ch Speaker System is an affordable way to add accurate reference monitoring with a subwoofer for enhanced bass response. The left and right speakers each offer 15 watts of power, while the 50-watt subwoofer provides a powerful low-end boost. And with 24-bit/96kHz digital inputs, the DM-2100 is perfect for use with Roland/BOSS digital studios and instruments, or with computer systems and more.

• Affordable 2.1-channel monitoring system with 24-bit/96kHz digital inputs

ADAMs A7 & A7X: the evolution of a legend

The predecessor to the A7X, the A7, became the most famous of all ADAM monitors in a very short time. Not only has it been reviewed over three dozen times with outstanding results, it has also received numerous awards. The A7 quickly gained mass appeal, praised in many of the worldʼs largest internet forums. Still today, the A7 are the reference monitors in many smaller studios.

With the A7X, ADAM Audio proudly presents the evolution of a legend. It takes everything that made the A7 such an outstanding speaker to a new level.

Driver technology

The first aspect that distinguishes the old from the new model is the X-ART tweeter. The ʽXʼ stands for ʽeXtended frequency responseʼ 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 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 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.
