A8H

The A8H is a 3-way active studio monitor from ADAM Audio designed for mid- to full-sized listening environments. It combines an 8-inch Multi-Layer Mineral woofer, a 3.5-inch Dome Cone Hybrid midrange driver, and a handmade X-ART tweeter with rotatable HPS waveguide, reaching 105 dB peak SPL and a frequency response down to 31 Hz. Available in left and right configurations.

Applications

Mid-field and full-range studio monitoring for recording, mixing, and mastering in medium to large rooms. The horizontal orientation and wide HPS waveguide dispersion suit wide-format mixing desks and multi-engineer environments. Available as left or right units to match asymmetric control room layouts.

Frequently asked questions

How does the DCH midrange driver differ from a standard cone or dome?
The 3.5-inch Dome Cone Hybrid (DCH) driver combines a dome and cone in a single one-piece unit, offering the imaging precision of a dome with the efficiency and low-distortion output of a cone. On the A8H it uses Multi-Layer Mineral cone material and is powered by a dedicated 70 W Class A/B amplifier.

What is the frequency range of the A8H?
The A8H reaches 34 Hz to 41 kHz at the -3 dB points, or 31 Hz to 45 kHz at the -6 dB points, with crossovers at 400 Hz and 3.0 kHz between the three driver stages.

Does the A8H require a subwoofer?
The A8H extends to 31 Hz at the -6 dB point, which covers the full range of most audio content. Whether a subwoofer is needed depends on the room acoustics and the specific low-frequency extension required for the application.
