Adam Audio A77H 7″ Active Studio Monitor Overview

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.

Future Proof Innovations 

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 A77H.

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.
