A77H

The A77H is a horizontally oriented three-way studio monitor from ADAM Audio, combining dual 7-inch Multi-Layer Mineral woofers, a 3.5-inch Dome Cone Hybrid midrange driver, and the German Handmade Precision X-ART tweeter. Delivering a frequency range of 34 Hz to 45 kHz and 340 W peak power, it suits large mixing environments and centre-channel roles in immersive audio configurations.

Applications

The A77H is designed for large control rooms, mastering suites, and immersive audio mixing environments. The horizontal form factor allows placement above or below screens, or on standard rack shelving, while the three-way design with dedicated midrange driver improves clarity across the 200 Hz to 3 kHz range most critical to vocal and instrument reproduction. It also serves as a centre-channel monitor in Dolby Atmos and other spatial audio configurations.

Frequently asked questions

What makes the A77H different from the A44H?
The A77H adds a 3.5-inch DCH midrange driver to the two-way A44H design, giving it a three-way architecture. This, combined with its dual 7-inch woofers and 340 W total peak power, extends the low-frequency response to 34 Hz (-6 dB) and raises the maximum SPL to 106 dB at 1 metre.

Can the A77H be used in an immersive audio setup?
Yes. Its horizontal cabinet and wide frequency range make it suited to centre-channel roles in immersive and 3D speaker systems, and it shares the same DSP platform and Ethernet control as the other A Series monitors.

Is third-party mounting supported?
Yes. Four M8 threaded inserts on the underside accept the optional A Series Mounting Plate, which connects to compatible wall, ceiling, and speaker pole mounting solutions.
