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 glass fiber polymer compound that helps create a clear sound, 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 response 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. ; Multi Layer 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 are specific to the driver used in each model. By combining this material with a magnet system, A Series woofers produce high output with low distortion, delivering a clean low end. ; ; Hybrid Amplification ; ; The A Series combines the best of both digital and analog worlds. The woofers are driven by Class D amplifiers that help produce linear performance while reducing distortion.
