The ADAM Audio S3H is a high-end, three-way active midfield studio monitor that combines immense power, advanced DSP technology, and precise acoustic design to deliver unmatched performance for professional recording and mixing environments.
Building on the legacy of the acclaimed ADAM Audio S3A and S3X-H monitors, the ADAM Audio S3H continues ADAM Audio’s tradition of innovation, offering pristine sound reproduction, an exceptionally wide frequency range, and an accurate, three-dimensional soundstage.
The ADAM Audio S3H features dual 7-inch (178mm) HexaCone bass drivers powered by a 500-watt Class D amplifier, delivering deep, distortion-free bass down to 30Hz with tight control and power. A 4-inch (102mm) DCH hybrid dome/cone midrange driver, driven by a 300-watt Class D amplifier, covers the critical 250Hz–3kHz range, combining the speed and precision of a dome with the dynamic depth of a cone for outstanding midrange detail.
For the high frequencies, ADAM’s hand-built S-ART (Accelerated Ribbon Technology) tweeter, paired with a precision-engineered HPS (High Precision Waveguide) and a 50-watt Class A/B amplifier, extends response to 50kHz, producing effortless clarity, natural air, and a wide sweet spot.
At the heart of the ADAM Audio S3H is a custom DSP engine that optimises crossover behaviour and frequency response across all drivers, ensuring perfect phase alignment and consistent performance. The DSP also provides extensive user equalisation, in-room voicing, and tuning options. It includes a factory EQ preset that emulates the legendary ADAM Audio S3A monitor response for users familiar with its tonal balance.
Additional DSP functions include limiter-based high-frequency driver protection, AES3 digital input processing, and future-ready expansion options. A USB interface enables firmware updates and full control of the DSP functions via computer software.
With a total RMS output of 1,350 watts, a frequency response of 30Hz–50kHz, and maximum SPL of 126dB per pair, the ADAM Audio S3H delivers full-range monitoring without the need for a subwoofer. Its horizontal design makes it ideal for midfield applications, offering powerful low-end performance, refined midrange articulation, and fatigue-free listening even during extended sessions. The result is a monitor that combines precision with musicality, providing engineers and producers with absolute confidence in their mixes.
