Adam Audio A77H 7-Inch 3-Way Powered Studio Monitor (Each)

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. OneStopMusic 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. OneStopMusic 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.

Adam Audio

Adam Audio (Advanced Dynamic Audio Monitors) is a Berlin-based professional studio monitor manufacturer founded in 1999, built around a single defining technology: the proprietary X-ART (Accelerated Ribbon Technology) tweeter. Inspired by Oskar Heil's 1960s Air Motion Transformer invention, ADAM Audio's ART tweeter accelerates air four to five times faster than conventional dome tweeters, delivering an exceptionally detailed and accurate high-frequency response that quickly earned the brand a devoted following among recording engineers, mixers, and mastering professionals worldwide. The game-changing ADAM Audio S3A monitor brought the brand to global prominence in the early 2000s, establishing the S Series as the flagship reference line and cementing ADAM Audio's reputation for precision and transparency at the highest level of professional monitoring. Today the brand offers four distinct monitor ranges to suit every studio environment and budget — the T Series for entry-level professional use, the A Series with DSP-equipped mid-range monitors, the flagship S Series reference monitors in horizontal and vertical configurations, and the D Series for desktop production setups — all complemented by a range of professional subwoofers. Acquired by the Focusrite Group in 2019, ADAM Audio continues to design and manufacture in Berlin, maintaining the rigorous engineering standards and acoustic precision that have made it one of the most trusted monitor brands in professional audio.
