The A44H offers a low-profile alternative to the A-Series A7V while delivering similar performance characteristics. 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 A44H 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 

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 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.  

Hybrid Amplification  

The A44H 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 

It 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 A44H 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. 

Voicings 

A Voicing is a pre-defined sound profile of the A44H monitors. On the back panel, you will find two different selections, UNR and Pure. Here you will also find the Ext option which is dedicated to the extended functionality that comes with A Control via the Ethernet connection. UNR or Uniform Natural Response is a dynamic, natural-sounding response curve of ADAM Audio’s own design, which stems from a variety of iconic ADAM Audio legacy products, including the preceding AX Series. Pure is a highly accurate and neutral-sounding option. The Ext option is dedicated to the extended functionality that comes with A Control via the Ethernet connection.

Bass Reflex System, Cabinets, and Mounting 

A44H cabinets build on the heritage of ADAM Audio and the AX Series in particular. In an evolutionary design, A44H cabinets have deeper beveling to further reduce diffraction. In addition, thicker baffle walls strengthen the cabinets and reduce internal vibrations, while a flared-port design optimizes airflow and reduces port noise. All A Series speakers include an underside mounting interface, giving you the flexibility to mount them wherever you need them.
