Adam Audio A4V Nearfield Studio Monitor

Rotatable HPS Waveguide & X-ART Tweeter 

ADAM Audio HPS (high-frequency propagation system) waveguide technology enables tweeters to disperse sound with controlled consistency, broad in the horizontal axis but tightly focused in the vertical plane. The A Series introduces a rotatable HPS waveguide design. You can shift A Series tweeters in 90-degree steps to continue to benefit from HPS waveguide technology whether you position the speakers horizontally or vertically.  

The A Series HPS Waveguide is made from a new glass fibre polymer compound that helps create a clear sound, free of unwanted resonance. The ADAM Audio X-ART tweeter is at the heart of the rotatable HPS waveguide. Handmade in Germany, the X-ART tweeter provides a precise transient response and reproduces the finest sonic details. This X-ART tweeter is used in every A Series speaker, providing a detailed, consistent sound across the product line. 

Multi-Layer Mineral Woofer 

A Series woofers are constructed with a unique blend of mineral stone fibres that have been baked together to create a lightweight but highly stable material. The mineral composition, layering and geometry of each cone is specific to the driver used in each model. By combining this material with a new magnet system, A Series woofers produce high output with low distortion, delivering a clean low-end. 

Midrange Driver

Adapted from the groundbreaking ADAM Audio DCH™ midrange driver used by the S Series speakers, the A Series midrange driver delivers a clean sound in a critical part of the frequency range where humans are especially sensitive to colouration of sound. Using a dedicated driver for the midrange further helps clarify lows and highs by eliminating the need for woofers to reproduce midrange frequencies and thus reducing distortion. 

Hybrid Amplification  

The A Series combines the best of both digital and analogue worlds. The woofers are driven by Class D amplifiers that help produce linear performance while reducing distortion. These amplifiers were chosen specifically for their power and efficiency, in terms of both energy consumption and sound reproduction. Low thermal dissipation allows for a smaller heat sink, which facilitated additional investment in the exceptional power and performance of the A Series. 

Tweeters and midrange drivers are powered by Class AB amplifiers which offer a smooth, natural reproduction of high frequencies. Each amplifier is optimized for its working range, resulting in a fine-tuned, properly aligned speaker. To reach this point, ADAM Audio carried out extensive measurements and listening sessions, trialling countless amplifiers and amplifier components.  

DSP-Based Electronics 

The A Series capitalizes on the transformative power of DSP-based electronics to provide greater tuning precision and better predictability than analogue-only speakers. With firmware that can be updated through an Ethernet connection, over time you can expect to integrate the latest DSP-based capabilities from ADAM Audio—including new filter types and features, plus alternative voicings.

A Solution for Every Space 

With five models of varying dimensions and specifications to choose from, finding the right speaker is simply a matter of taste and understanding the acoustic requirements of your space. For added flexibility when it comes to speaker positioning, the rotatable HPS waveguide means each speaker can be used in a horizontal or vertical position with minimal compromise in sound quality. Room adaptation options directly on the backplate of the monitor help address common speaker placement issues such as bass overrepresentation caused by nearby walls and surfaces.

Superior Audio Performance 

Every aspect of the A Series’ design, material, and components contributes toward exceptional sound quality and improved output when comparing similar models of the preceding AX Series. 

The combination of Class D amplifiers used in A Series woofers, and the Class AB amplifiers found in the tweeters deliver impressive SPL across the range and an ultra-low frequency response. The use of digital signal processing enables the more advanced features found in the A Series.  

All A Series speakers come equipped with an X-ART tweeter enclosed in a tailor made HPS waveguide. The high quality of the tweeter materials, folded by hand in Berlin, combined with the precise propagation control of the waveguide, results in superior dispersion of high frequencies over short and long listening distances. 

A Series woofers are constructed from multiple layers of mineral stone fibres baked together to create a lightweight but highly stable material that helps eliminate partial vibrations and other sonic impurities. By combining that material with a new magnet system, A Series woofers produce high output with low distortion, delivering a clean sound for low-end material. 

The elegant design of A Series cabinets also contributes toward superior audio performance. Specifically, the cabinets have deeper bevelling to minimize diffraction, and thicker baffle walls that reduce vibrations within the enclosure. In addition, a flared-port design reduces port noise compared with AX Series speakers by optimizing airflow. 

Superior Midrange

The A Series features two models with dedicated midrange drivers. The A77H and A8H boast the most detailed sound of the A Series thanks to the innovative midrange driver, which descends from the flagship S Series range. The addition of a midrange driver also helps clarify lows and highs by eliminating the need for woofers to reproduce midrange frequencies.

Truthful Mixing 

The A Series features 2 selectable voicing options found directly on the back panel of the monitors. “Pure” is a highly accurate and neutral sounding option. This is a super flat setting, offering an honest representation from your speakers and making it ideal for mixing, mastering and critical listening applications. 

Characterful Sound  

The A Series also offers the characterful and present sound you would expect from ADAM Audio. “UNR” or “Uniform Natural Response™” is a dynamic, natural-sounding voicing that is selectable on the back panel of the monitors. Its design stems from a variety of iconic ADAM Audio legacy products, including the preceding AX Series. It lends itself to production, composition and song writing as its engaging sound can give you more room for creativity and flow. It is also a great option whenever you want to use your speakers simply to enjoy some good music.

The ADAM Audio A Series delivers highly accurate, transparent sound across a full line of monitors. The line also boasts a wealth of voicing and room adaptation options that can be controlled remotely and in real time via A Control, a free-to-download software application from ADAM Audio (available for Windows and MacOS). A Control also facilitates a highly anticipated feature of the series, delivered in collaboration with calibration experts Sonarworks. Via A Control, users can upload and store SoundID Reference calibration profiles directly on the DSP of A Series monitors without the need to run the SoundID Reference application or any additional DAW plugin.

Warranty

You have the possibility to extend the warranty period of all your ADAM products by up to three years to a total of five years. You can set this up in a few seconds in the MyADAM section of ADAM's website. The decisive factor is the date of the invoice.
