The S3H builds on the successes of ADAM Audio s most popular studio monitors, the S3A and S3X-H, and, like its predecessors, sets new standards in terms of technical innovation and design. 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.
