NOTHING COMPARES
Incorporating two 7-inch woofers, a midrange driver, and ADAM Audio’s X-ART tweeter, the A77H delivers an ultra-wide frequency range.
The addition of the midrange driver helps produce clear sound in the most sensitive range of human hearing. Rotatable HPS waveguide technology and onboard DSP allow you to tune the sound for your precise requirements.
EXPLORE THE TECHNOLOGY ADAM Audio monitors have earned a worldwide reputation for the innovations that we have established in the field of loudspeaker technology. Here you can explore the technology of the A77H.
