Adam Audio A77H Nearfield Studiomonitor  

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. Adam Audio HPS (high-frequency propagation system) waveguide technology enables tweeters to disperse sound with controlled consistency, broad on the horizontal axis but tightly focused in 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 fibre 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 precise transient responses and reproduces the finest sonic details.?This X-ART tweeter is used in every A Series speaker, providing a detailed, consistent sound across the product line.
