ADAM Audio A77H Active Studio Monitor

With an added midrange driver for even clearer sound than its predecessor, the A77X, the ADAM Audio A77H delivers rich, detailed audio across a wide area.

An advanced successor to the A77X, the A Series A77H is a true three-way midfield monitor that capitalizes on the latest ADAM Audio technologies to deliver a rich, spacious, and enveloping sound. 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. 

A Solution for Every Space

With five models of varying dimensions and specifications to choose from, finding the right speaker is simply a matter of taste and understanding the acoustic requirements of your space. For added flexibility when it comes to speaker positioning, the rotatable HPS waveguide means each speaker can be used in a horizontal or vertical position with minimal compromise in sound quality. Room adaptation options directly on the backplate of the monitor help address common speaker placement issues such as bass overrepresentation caused by nearby walls and surfaces.

Superior Audio Performance

Every aspect of the A Series' design, material, and components contributes toward exceptional sound quality and improved output when comparing similar models of the preceding AX Series.

The combination of Class D amplifiers used in A Series woofers, and the Class AB amplifiers found in the tweeters deliver impressive read more SPL across the range and an ultra-low frequency response. The use of digital signal processing enables the more advanced features found in the A Series.

All A Series speakers come equipped with an X-ART tweeter enclosed in a tailor made HPS waveguide. The high quality of the tweeter materials, folded by hand in Berlin, combined with the precise propagation control of the waveguide, results in superior dispersion of high frequencies over short and long listening distances.

A Series woofers are constructed from multiple layers of mineral stone fibers baked together to create a lightweight but highly stable material that helps eliminate partial vibrations and other sonic impurities. By combining that material with a magnet system, A Series woofers produce high output with low distortion, delivering a clean sound for low-end material.

The elegant design of A Series cabinets also contributes toward superior audio performance. Specifically, the cabinets have deeper beveling to minimize diffraction, and thicker baffle walls that reduce vibrations within the enclosure. In addition, a flared-port design reduces port noise compared with AX Series speakers by optimizing airflow.

Superior Midrange

The A Series features two models with dedicated midrange drivers. The A77H and A8H boast the most detailed sound of the A Series thanks to the innovative midrange driver, which descends from the flagship S Series range. The addition of a midrange driver also helps clarify lows and highs by eliminating the need for woofers to reproduce midrange frequencies.

Truthful Mixing

The A Series features 2 selectable voicing options found directly on the back panel of the monitors. "Pure" is a highly accurate and neutral sounding option. This is a super flat setting, offering an honest representation from your speakers and making it ideal for mixing, mastering and critical listening applications.

Characterful Sound

The A Series also offers the characterful and present sound you would expect from ADAM Audio. "UNR" or "Uniform Natural Response(TM)" is a dynamic, natural-sounding voicing that is selectable on the back panel of the monitors. Its design stems from a variety of iconic ADAM Audio legacy products, including the preceding AX Series. It lends itself to production, composition and songwriting as its engaging sound can give you more room for creativity and flow. It is also a great option whenever you want to use your speakers simply to enjoy some good music.
