ADAM Audio HPS (high-frequency propagation system) waveguide technology enables tweeters to disperse sound with controlled consistency, broad on 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 fiber 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 precise transient responses 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 of woofers are constructed with a unique blend of mineral stone fibers that have been baked together to create a lightweight but highly stable material. The mineral composition, layering, and geometry of each cone are 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 the coloration of the 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 analog 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.  

DSP-Based Electronics 

The A-Series capitalizes on the transformative power of DSP-based electronics to provide greater tuning precision and better predictability than analog-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.  

A Control (Real-Time Remote Control) 

The DSP-based functionality of all A-Series monitors can be controlled remotely and in real-time over Ethernet using the free-to-download A Control software. A Control is available to download for Windows and macOS in the MyADAM area of for customers who have registered their A-Series monitors

Room Correction and Sonarworks Integration 

A Series speakers are designed to be adaptable to changing requirements, preferences, and environments. Using the A Control software, you can push advanced filters directly to an embedded platform onboard the monitors to help compensate for imperfect room acoustics.
