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.
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.
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.
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.
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.
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.
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.
