Adam Audio -Raising the Standards of Audio Reproduction

ADAM Audio monitors are an established favorite among audio engineers and music lovers. It was founded by a physicist called Klaus Heinz in Berlin in 1999 who was responsible for the development of the ART (Accelerating Ribbon Technology) tweeter that ultimately was the reason for the company’s establishment. By initially developing a new approach to monitor design and then steadily building upon it with innovations in every part of the signal and soundwave path, the Adam company has established a reputation for being less of a product marketing business and more of a cutting-edge research house. Let’s have a look at the state-of-the-art and cutting edge technology that has won Adam audio so many fans and awards around the world.

What is X-ART technology?

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. In the X-ART tweeter, a folded ribbon design is used which can move air 4 times faster than the actual folds themselves are moving, producing phenomenally quick transient response with extremely low distortion. By allowing air to move in a more natural, quicker way ADAM had created a fresh tweeter design to complement the advances in driver technology available on the market today, with new materials like rare-earth magnets and super strong magnet foils.

The new improved X-ART tweeter can be found across their entire line; from the entry-level F-Series, to the award-winning AX-Series, to the boutique purity of the SX-Series. The lack of a traditional voice coil in X-ART tweeters results in a very flat impedance. These tweeters have a high efficiency (approximately 96 dB/W/m), a perfectly linear impedance (3.9 ±0.21), an equally perfect phase response (±1° within the utilized bandwidth), excellent directivity characteristics and a superb power handling capacity; plus, the neodymium magnets and yoke (ring) utilized in the X-ART units result in perfect magnetic shielding.

HexaCone woofers are an integral component in most of ADAM’s monitors/speakers. The core is a honeycomb Nomex structure that makes them both extremely light and very stiff. The front and back of the cone have been coated with Kevlar, one of the most advanced synthetic materials available. Kevlar withstands elongation by a force factor greater than 1000 times that of steel, enabling the cone to resist deformation. These woofers are far more rigid than paper, polypropylene or aluminum devices of similar dimensions. Due to this rigidity, break up resonances in the diaphragm cone are prevented.

Adam Audio’s AX series is an improvement on the design of the highly successful and critically acclaimed A series which have won a string of awards and received over four dozen glowing reviews in the world's top magazines. Many technical innovations from the higher end SX-Series can also be found in the AX models. Chamfered upper corners on the cabinet fronts minimize edge diffraction so that phase cancellation is not an issue. Speaker interiors are equipped with a special fleece that prevents disturbing internal resonances as well as ensuring better bass reflex tuning.




The small A5 managed to make itself a big name in both professional environments as well as in computer or desktop applications. A wealth of truly outstanding reviews and many awards helped this speaker accomplish tilte of " Top choice for small sized studio monitor ".

ADAM Audio A5X Specifications:

  • Mid-Woofer Basket: 5.5" (145 mm)
  • Voice coil: 1.5" (32 mm)
  • Cone material: Carbon/Rohacell/Glass Fiber
  • Tweeter Type: X-ART





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 world’s 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.

ADAM Audio A7X Specifications: 

  • Mid-Woofer Basket: 7" (175 mm)
  • Voice coil: 1.5" (38 mm)
  • Cone material: Carbon/Rohacell/Glass Fiber
  • Tweeter Type: X-ART






    The legendary ADAM Audio A8X Powered Monitors. With its power and radiation characteristics, the ADAM Audio A8X Powered Monitor is suitable for both nearfield and midfield monitoring. With a price/performance ratio that could hardly be better, this monitor is a perfect entry into these monitoring fields.

    ADAM Audio A8X Specifications:

    • Suitable for both nearfield and midfield monitoring
    • Equipped with the X-ART tweeter and a large (8.5"") midwoofer
    • 50W A/B tweeter amplifier
    • 150W PWM midwoofer amplifier
    • Upper corners slanted to minimize reflections
    • Large, double bass reflex tubes
    • ±4dB gain for the high frequencies
    • Two shelf filters for the high and low frequencies





    ADAM Audio monitors are found in top recording and post production studios all over the world, and now take their extensive knowledge of studio speaker technology and have created a more affordable entry line of monitors. The F5 is the smallest of the near field monitors in the F-series and has been designed for listening environments with somewhat limited space.

    ADAM Audio F5 Features:

    • Smaller of the near field monitors in the F-series
    • Designed for listening environments with somewhat limited space
    • 5” Woofer made from carbon and paper and a 25mm voice coil

    ADAM Audio F5 Specifications:

    • Mid-Woofer Basket: 5 inch (127 mm)
    • Voice coil: 1 inch (25 mm)
    • Cone material: Glass fibre/paper





    The Adam F7 active nearfield monitor is the bigger brother of the company's F5. The F7 can be thought of as a lower-cost version of Adam's popular A7X, and although the F7's cabinet and woofer are built overseas, the all-important folded-ribbon tweeter is still made at Adam's factory in Berlin.

    ADAM Audio F7 Specifications:

    • Basket: 7" (177 mm)
    • Voice coil: 1.5" (37 mm)
