SUPREME MONITORINGThe 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.The A8H is available in a left and right version.German Handmade Precision X-ART Tweeter with rotatable HPS waveguide8” Woofer (Multi-Layer Mineral)3.5″ DCH Midrange DriverTotal Peak Amp.
