The dual 7-inch bass drivers, powered by a 500 W Class D amplifier, offer flawless reproduction of frequencies all the way down to 30 Hz. ADAM Audio’s newly developed DCH, a 4-inch hybrid dome/cone mid-range driver, is powered by a 300 W Class D amplifier and handles audio above 250 Hz and below 3 kHz, its leading-edge hybrid design offering the sonic advantages of both cone and soft-dome drivers in a single, one-piece unit. Frequencies above 3 kHz are routed to the innovative combination of the S-ART treble driver (each handmade at ADAM Audio’s Berlin factory), the new precision HPS waveguide, and a 50 W Class A/B amplifier. The result of all this innovation is a beautifully transparent three-dimensional soundscape, with an extensive sweet spot.

The S Series’ custom-designed DSP optimizes the loudspeaker crossovers to create linear responses for the entire range, as well as providing user equalization and in-room tuning/voicing functions. A unique feature of the S3H’s DSP options is a built-in factory EQ preset that emulates the response of ADAM Audio’s legendary S3A monitor. The DSP also handles the limiter-based high-frequency driver protection, processes the signals from the AES3 digital inputs, and will in time facilitate various expansion options. Software updates can be carried out with ease via the associated USB port, which also allows users to connect computers and control the speakers’ DSP functions via a software front-end.

With its massively powerful amplification and three-way design (optimally configured for use horizontally), the S3H was conceived as a midfield monitor, but can be employed equally well in more compact listening environments. As with all ADAM Audio designs, the sound is punchy but musical, with crystal-clear reproduction of the all-important mid-range.

The S3H’s wide-ranging frequency response, its power amps’ instantly available, plentiful headroom, and the lack of need for additional subwoofers should appeal to any audio professional looking for a stand-alone, full-frequency active solution for their recording studio, one which provides equally detailed audio information at any volume setting, loud or quiet. Whatever your preferred output level, the S3H’s vibrant authenticity is a spur to creativity for producers, engineers and musicians everywhere, and its sound remains remarkably unfatiguing, even when working uninterrupted for extended periods.
