Adam Audio A8H 3-way 8" Woofer


The pinnacle of the A Series, the A8H is a 3-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.

The A8H is available in a left and right version.
