ADAM Audio A77H Powered Three-Way Midfield Studio Monitor

The waveguide technique employed by ADAM Audio HPS (high-frequency propagation system) tweeters allows them to disseminate sound with controlled consistency, broad on the horizontal axis yet tightly focused in the vertical plane. The A-Series is the first to have a rotating HPS waveguide. Whether you set the speakers horizontally or vertically, you can benefit from HPS waveguide technology by shifting A Series tweeters in 90-degree steps. The A-Series HPS Waveguide is constructed of a unique glass fiber polymer composite that aids in the creation of a clear, resonance-free sound. The rotating HPS waveguide is powered by the ADAM Audio X-ART tweeter. The X-ART tweeter is handcrafted in Germany and enables precise transient responses and reproduction of the finest acoustic characteristics.

Mineral Woofer with Multiple Layers

A Series of woofers are made from a special blend of mineral stone fibers that have been baked together to create a lightweight but extremely stable material. Each cone's mineral composition, layering, and geometry are unique to the driver used in the model. A Series woofers produce strong output with little distortion and a clear low-end by combining this material with a novel magnet technology.

Hybrid Amplification

The A-Series is a hybrid of digital and analog technology. Class D amplifiers drive the woofers, which aid to create linear performance while minimizing distortion. These amplifiers were chosen for their power and efficiency, both in terms of energy usage and sound reproduction. Low thermal dissipation allows for a smaller heat sink, allowing for more investment in the A-Series' excellent power and performance.

Electronics with a Digital Signal Processor (DSP)

The A-Series takes advantage of DSP-based electronics' revolutionary capacity to give more tuning precision and predictability than analog-only speakers. With firmware that can be updated via Ethernet, you can expect to see the latest ADAM Audio DSP-based capabilities, such as additional filter types and features, as well as alternate voicings, over time.

Room Adaptation

There are four bands of room adaptation equalization on the back panel of A-Series speakers: Bass, Desk, Presence, and Treble. Each band can be adjusted in predetermined increments, providing over 100 tuning possibilities to assist compensate for common acoustic issues caused by speaker placement.

A Control (Real-Time Remote Control) 

All A-Series monitors' DSP-based features can be controlled remotely and in real-time over Ethernet using the free A Control program. Customers who have registered their A-Series monitors can obtain a Control for Windows and macOS from the MyADAM section of

Room Correction and Sonarworks Integration 

Speakers in the A-Series are meant to adapt to changing needs, tastes, and situations. Advanced filters can be immediately pushed to an embedded platform onboard the monitors using the A Control software to help adjust for poor room acoustics.
