ADAM Audio A77H 7-Inch Three-Way Powered Midfield Studio Monitor

The ADAM Audio A77H is a true three-way midfield monitor built for precision listening in professional and project studios. Dual 7″ woofers, a dedicated 3.5″ midrange driver, and the X-ART ribbon tweeter work together to deliver rock-solid imaging, deep bass down to 34 Hz, and crystal-clear highs up to 45 kHz.

Tri-amped with high-power Class-D (250 W for each woofer), Class-AB (70 W midrange), and Class-AB (20 W tweeter) amplification, the A77H can reach up to 106 dB SPL per speaker without distortion. Onboard DSP controls and Ethernet connectivity via the free A Control app let you fine-tune EQ, voicings, and room-correction settings from anywhere in your studio.
