The pinnacle of the A Series, the A8H is a three-way speaker that delivers the extremely accurate and analytical sound required for critical-listening environments. The A8H incorporates an 8-inch resonant Multi-Layer Mineral (MLM) fiber woofer, innovative midrange driver, and handmade precision X-ART tweeter, which together produce an ultra-wide frequency response. Like the other members of the A Series family, the A8H gives you tremendous flexibility for fine-tuning the sound through rotatable HPS waveguide technology and onboard DSP. At home across a full range of audio applications in mid-to full-sized spaces, the A8H is the right choice when you’re looking for the most detailed representation of your audio.HPS Waveguide TechnologyThe 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 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. Rotatable HPS Waveguide and X-ART TweeterThe 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 precise transient responses and reproduces the finest sonic details. This X-ART tweeter is used in this speaker, providing a detailed, consistent sound across the product line. Multi-Layer Mineral Woofer The A8H's woofer is constructed with a unique blend of mineral stone fibers that have been baked together to create a lightweight but highly stable material. By combining this material with a new magnet system, this woofer produces high output with low distortion, delivering a clean low-end. Midrange DriverAdapted from the groundbreaking Adam Audio DCH midrange driver used by the S Series speakers, the A8H's midrange driver delivers a clean sound in a critical part of the frequency range where humans are especially sensitive to the coloration of the sound. Using a dedicated driver for the midrange further helps clarify lows and highs by eliminating the need for woofers to reproduce midrange frequencies and thus reducing distortion.Hybrid Amplification The A8H's woofer includes a Class D amplifier that helps produce linear performance while reducing distortion. This amplifier has both power and efficiency, in terms of both energy consumption and sound reproduction. The low thermal dissipation allows for a smaller heat sink, which facilitated additional investment in the exceptional power and performance of the A8H monitor.DSP-Based Electronics The A8H capitalizes on the transformative power of DSP-based electronics to provide greater tuning precision and better predictability than analog-only speakers. With firmware that can be updated through an Ethernet connection, over time you can expect to integrate the latest DSP-based capabilities from Adam Audio, including new filter types and features, plus alternative voicings.Room Adaptation On the back panel of the Adam Audio A8H speaker, you will find four bands of room adaptation equalization including Bass, Desk, Presence, and Treble. Each band is adjustable in predefined steps, offering more than 100 tuning options to help compensate for the typical acoustic problems that arise from speaker placement.VoicingsThis monitor's Voicing is a pre-defined sound profile. There are two different options on the back panel, UNR, and Pure. The Ext option is dedicated to the extra functionality that comes with A-Control via Ethernet connection.
