ADAM Audio A8H 8-inch Powered Studio Monitor Overview

Audio professionals who need full-range audio in mid-to-full-sized spaces will be impressed with the left ADAM Audio A8H, an extremely accurate 8″ 3-way studio monitor speaker that delivers rich, spacious, and enveloping sound in critical listening environments.

A 250W RMS Class-D amplifier powers the 8″ Multilayer Mineral (MLM) woofer, while 70W + 20W Class-AB amplifiers drive the MLM midrange driver and X-ART tweeter with HPS waveguide to provide an ultrawide frequency range. The midrange driver helps produce clear sound in the most sensitive range of human hearing. The rotatable High-Frequency Propagation System (HPS) waveguide technology and onboard DSP allow you to fine-tune the speakers to your precise requirements.

Rotatable HPS Waveguide and X-ART Tweeter

• ADAM Audio HPS (high-frequency propagation system) waveguide technology enables tweeters to disperse sound with controlled consistency, broad in the horizontal axis but tightly focused on the vertical plane. The A Series introduces a rotatable HPS waveguide design. You can shift A Series tweeters in 90-degree steps to continue to benefit from HPS waveguide technology, whether you position the speakers horizontally or vertically.
• The A Series HPS Waveguide is made from a new glass-fiber polymer compound that helps create a clear sound, free of unwanted resonance. The ADAM Audio X-ART tweeter is at the heart of the rotatable HPS waveguide. Handmade in Germany, the X-ART tweeter provides a precise transient response and reproduces the finest sonic details. This X-ART tweeter is used in every A Series speaker, providing a detailed and consistent sound across the product line.

Multilayer Mineral Woofer

A Series woofers are constructed with a unique blend of mineral stone fibers that have been baked together to create a lightweight but highly stable material. The mineral composition, layering, and geometry of each cone is specific to the driver used in each model. By combining this material with a new magnet system, A Series woofers produce high output with low distortion, delivering a clean low-end.

Midrange Driver

Adapted from the ADAM Audio DCH midrange driver used by the S Series speakers, the A Series midrange driver delivers a clean sound in a critical part of the frequency range, where humans are especially sensitive to coloration of sound. Using a dedicated driver for the midrange helps clarify lows and highs by eliminating the need for woofers to reproduce midrange frequencies, and so it reduces distortion.

Hybrid Amplification

• The A Series combines the best of both digital and analogue worlds. The woofers are driven by Class-D amplifiers that help produce linear performance while reducing distortion. These amplifiers were chosen specifically for their power and efficiency, in terms of both energy consumption and sound reproduction. Low thermal dissipation allows for a smaller heat sink, which facilitated additional investment in the exceptional power and performance of the A Series.
• Tweeters and midrange drivers are powered by¿Class-AB amplifiers, which offer smooth and natural reproduction of high frequencies. Each amplifier is optimized for its working range, resulting in a fine-tuned, properly aligned speaker. To reach this point, ADAM Audio carried out extensive measurements and listening sessions, trialing countless amplifiers and amplifier components.
