Audio professionals who need full-range audio in mid-to-full-sized spaces will be impressed with the right Adam Professional 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.
