Adam Audio A77H Active Midfield Bass Reflex Monitor
The A77H is a true three-way midfield monitor that capitalizes on the latest ADAM Audio technologies to deliver a rich, spacious, and enveloping sound.
NOTHING COMPARES
Incorporating two 7-inch woofers, a midrange driver, and ADAM Audio’s X-ART tweeter, the A77H delivers an ultra-wide frequency range.
The addition of the midrange driver helps produce clear sound in the most sensitive range of human hearing. Rotatable HPS waveguide technology and onboard DSP allow you to tune the sound for your precise requirements.

EXPLORE THE TECHNOLOGY
ADAM Audio monitors have earned a worldwide reputation for the innovations that we have established in the field of loudspeaker technology. Here you can explore the technology of the A7V.
A CONTROL REMOTE SOFTWARE
The DSP-based functionality of all A Series monitors can be controlled remotely and in real time over ethernet using A Control.
ROTATABLE HPS WAVEGUIDE & X-ART TWEETER
Made from a new glass fiber polymer compound, the HPS waveguide enables the X-ART tweeter to disperse sound in space with controlled consistency.
BASS REFLEX SYSTEM, CABINETS AND MOUNTING
The new A Series cabinets build on the heritage of ADAM Audio and the AX Series in particular.
AUTOMATED ROOM CORRECTION WITH SONARWORKS
ADAM Audio is proud to partner with Sonarworks on an automated room correction solution that runs directly on the DSP of A Series monitors.
Hybrid Amplification
The A Series combines the best of both digital and analog worlds.
Multi-Layer Mineral Woofer [MLM]
The latest materials and advanced analysis and design processes have led to the development of our new long-throw woofers.
Midrange Driver
A Series midrange drivers deliver clean sound in the critical part of the frequency range where humans are especially sensitive to coloration of sound.
Voicings
A “Voicing” is a pre-defined sound profile of an A Series monitor. On the back panel, you will find two different selections, “UNR” and “Pure”.
Room Adaptation
On the back panel of A Series speakers, you will find four bands of room adaptation equalization: Bass, Desk, Presence and Treble.
Digital Signal Processing
The A Series capitalizes on the transformative power of DSP-based electronics to provide greater tuning precision than analog-only speakers.
