A 4.5” (basket) driver handles the lower registers. The diaphragm is made from carbon fiber, a material that is very light but very stiff and therefore capable of delivering colouring-free sound. Two built-in 25 Watt amplifiers powers each of the drivers directly.

Stereolink

A very handy and exclusive technology found in the two smaller AX monitors is the Stereolink. This is accomplished by a pair of additional RCA connections that allow for a bypass of the second stereo channel to the other speaker.

This new technology connects two A3X speakers in such a manner as to allow the user the option to control the overall stereo volume of the system from either speakerʼs gain control. This makes the A3X a natural for "mixer-less” desktop applications where overall system volume needs to be adjusted easily.

Controls and Connectors

The front of the A3X sports dual ports for surprisingly low frequency response down to 60Hz. The front panel also has power and gain controls. The rear panel includes a tweeter gain control as well as balanced (XLR) jacks and unbalanced (RCA) jacks, allowing for greater connection flexibility. There are also two M6 (6 mm) metric screw threads for stand/wall mounting.

Review: "Highly recommended“

"Iʼve used various monitors for my computer work before, but never of the caliber of the A3X series. Before these, I would have to redo my mixes significantly when transitioning from the small cheapies to the big 'real ones'. The ADAM Audio A3Xʼs save me a step by providing both great sound in a compact format and by changing mundane audio task-work into a quality listening experience. If you use good monitors from the outset, youʼll learn your music that much faster so that when it comes time for mixdown and mastering on your big boxes, youʼll already be acclimated to your songʼs subtler sonic aspects—aspects revealed only by the A3Xʼs with their sweet, smooth top end, and impressive handling of bass frequencies. Highly recommended.“

Review: "...one of the best compact monitors“

"ADAM´s A3X as the smallest monitor with a X-ART tweeter to date has convinced us in every respect. It´s one of the best compact monitors we have ever reviewed and with its almost shameless low price it´s worth every penny. (Professional Audio, 05/10)

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
• Powered bass reflex speakers with 15 watts per side and flat frequency response
• Active subwoofer with 50-watt amplifier for increased low end
• Front-mounted controls convenient located on right speaker
• Coaxial and optical digital inputs, plus analog inputs (RCA and 1/4-inch type)
• Sleek black wooden cabinets with magnetic shielding

The compact LSR6325P-1 provides exceptional performance for use in applications
where accuracy is a must, but space is limited. With a 5.25 in. high-excursion woofer,
a damped titanium composite tweeter, and 150 Watts of amplification, it outperforms
many larger systems. When used with the LSR6312SP Subwoofer, the LSR6325P-1
is the heart of an exceptionally accurate yet space efficient full-range system.

Features:
High-performance bi-amplified design with patented JBL transducer technology.
Front panel volume and power controls.
Integrated mounting points for horizontal and vertical suspension.
Titanium composite high frequency device with elliptical oblate spheroidal waveguide.
Shielded for use next to video monitors.
Built in high-pass filtering for use with optional subwoofer.
User selectable workstation boundary compensation.
Powered monitors with 5.25" woofers and 1" titanium composite dome tweeters
100 watts power for low frequencies, 50 watts for highs
Cast aluminum enclosure for structural rigidity and light weight
Magnetically shielded for interference-free use near CRTs and other electronic gear
Linear Spatial Reference technology ensures even frequency response at the mix position

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.
