The Adam Audio A77H 7-inch 3-way powered studio monitor is a horizontally oriented midfield reference monitor that builds on the fan-favourite A77X with a modern 3-way driver system comprising dual 7-inch MLM woofers, a 3.5-inch MLM midrange driver, and the X-ART ribbon tweeter — delivering an extraordinary frequency response from 37Hz to 41kHz in a wide-format enclosure designed to sit above or below a studio display. As a result, engineers working in midfield monitoring positions gain a complete, high-resolution picture of the audio across the full spectrum, with the dedicated 3.5-inch midrange driver handling the critical 400Hz to 3kHz range where the most important mix decisions happen — delivering clarity and separation that 2-way monitors simply cannot match. A total of 340W of amplification is distributed across a 250W amp for the dual woofers, a 70W amp for the midrange, and a 20W amp for the X-ART tweeter, providing ample power and headroom for accurate monitoring at professional listening levels. In addition, seamless crossovers at 400Hz and 3kHz ensure a coherent, phase-accurate transition between all three drivers, while onboard DSP-based tuning enables room adaptation. Marshall Music South Africa stocks the Adam Audio A77H 7-inch 3-way powered studio monitor for South African studios building a professional midfield monitoring setup with full-range 3-way accuracy.

Full-Spectrum Midfield Performance From the Adam Audio A77H 7-Inch 3-Way Powered Studio Monitor

Whether you’re mixing a full album, mastering a record, or working on a film soundtrack in a medium-to-large control room, the Adam Audio A77H 7-inch 3-way powered studio monitor provides the resolution, dynamics, and frequency coverage needed for professional-level decisions. The dual 7-inch MLM woofers extend bass response to 37Hz with control and definition, while the X-ART ribbon tweeter resolves high-frequency detail to 41kHz — ensuring the A77H reveals everything in the audio from the deepest sub-harmonics to the finest transient detail. A maximum peak SPL of 106dB per speaker ensures the A77H has the headroom to fill a medium or large control room at professional monitoring levels. However, the horizontal format is the A77H’s defining practical advantage — its 20⅞-inch width allows it to sit naturally above or below a large display on a standard meter bridge or custom bracket, keeping the sweet spot at ear level without compromising the stereo image. Marshall Music South Africa recommends the Adam Audio A77H 7-inch 3-way powered studio monitor to South African mixing and mastering engineers who need a full-range, 3-way midfield monitor in a professional horizontal format.
