ADAM Audio S3H

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.

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.

“I just unboxed a pair last week and they offer a spectacular listening experience. They are a mid-field, but I had them comfortably atop an SSL console’s meter bridge and I couldn’t help being impressed. (…) These are a ‘buy’.”

Kevin Becka
MIX Magazine

“With the S3H ADAM Audio did everything right! Good mixes sound great, mistakes are disclosed without a hint of mercy […]. The impressive sound reproduction capabilities do not have to hide from any monitor in this price range (and above) that I know of and with the extensive EQ options every taste and requirement should be satisfied and fulfilled.”

Peter Könemann

“Extremely modern, high-class sound impact and precision with an excellent construction […], essential for the success of the S3H. […] The new reference in this segment.”

Luca Pilla

“So what’s to dislike about the ADAM S3H? Nothing, I’m convinced. “

Brad Watts
Audio Technology

„There are details I could discern on the ADAMs that I couldn’t hear on other monitors anywhere near their price. And the real miracle to me is that the ADAMs provide all that detail without being at all harsh, “forward” or fatiguing at all – they are exceptionally well balanced all across the spectrum.“

Jim Daneker

“The S3H combines musicality and precision harmoniously. These speakers are fun to listen to and will play back music without covering up any of the details, neither coloring nor imbalancing them. […] I am happy to state that the S3H is the best ADAM speaker I have heard so far.”

Fritz Fey
Studio Magazin

“ADAM Audio’s S3H is a first-class, extremely well-designed, flexible and versatile studio monitor. Particularly impressive are its sonic accuracy and impulse response, which trump those of its predecessor (N.B. this refers to one of ADAM’s previous loudspeakers, the S3X-H). Quite simply, the S3H relieves the earlier speaker of its title as the dependable reference monitor to choose.”
