Adam Audio A77H 7 inch Powered Studio Monitor

ADAM Audio A77H 7-inch Powered Studio Monitor

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.
