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.
Room Adaptation
On the back panel of A Series speakers, you will find four bands of room adaptation equalization: Bass, Desk, Presence and Treble. Each band is adjustable in predefined steps, offering more than 100 tuning options to help compensate for the typical acoustic problems that arise from speaker placement.
