Know before you buy
Unlike two-way speakers that force a single woofer to handle both low and mid frequencies, the A77H uses dedicated drivers for bass, midrange, and high frequencies. This separation allows each driver to operate within its optimal range, resulting in significantly better clarity and less distortion in the critical midrange.
The A77H is specifically designed as a horizontal monitor. While the waveguide is rotatable to maintain proper dispersion, the cabinet's internal architecture and driver alignment are optimized for a horizontal layout.
The A77H integrates with Sonarworks SoundID Reference software, allowing you to measure your room's acoustic response and upload a correction profile directly to the speaker's internal DSP. This ensures your monitoring remains accurate regardless of your room's specific acoustic challenges.
While the A77H is a powerful midfield monitor, its performance is best realized in medium-to-large rooms where you have enough space for the sound to develop. In a very small, untreated room, its 500W of power and wide frequency response might be difficult to manage without professional acoustic treatment.
The X-ART tweeter uses a folded ribbon design to move air more efficiently than traditional dome tweeters, providing a highly detailed and fast transient response. The HPS waveguide ensures that these high frequencies are dispersed consistently across a wide horizontal area while keeping vertical dispersion controlled, which helps reduce unwanted reflections from your desk.
No, the A77H is an active monitor, meaning it has internal amplifiers specifically matched to its drivers. You only need to connect your audio interface or monitor controller directly to the speakers.
