S3H

The S3H is a 3-way active mid-field studio monitor from ADAM Audio, designed for horizontal orientation in medium to large control rooms. It uses two 7-inch HexaCone woofers, a 4-inch Carbon Composite Dome Cone Hybrid midrange driver, and a handmade S-ART tweeter with HPS waveguide, delivering at least 126 dB peak SPL per pair and frequency response reaching 30 Hz. Total RMS amplifier power is 1350 W across three dedicated amplifier stages.

Applications

Mid-field monitoring for professional recording studios, mastering facilities, broadcast control rooms, and post-production suites requiring full-range playback without a subwoofer. The horizontal 3-way configuration and wide sweet spot suit multi-engineer environments and wide format mixing desks. AES3 digital input enables direct connection to digital audio workstations. The built-in S3A emulation EQ preset allows direct comparison with ADAM Audio's earlier reference design.

Frequently asked questions

Does the S3H need a subwoofer?
The S3H reaches 30 Hz at the -20 dB point with 1350 W of onboard amplification and at least 126 dB peak SPL per pair, covering the full range of most professional audio content without additional subwoofer support.

What is the DCH midrange driver in the S3H?
The 4-inch Dome Cone Hybrid (DCH) uses a Carbon Composite cone in a one-piece dome-and-cone construction, handling frequencies from 250 Hz to 3 kHz. It is powered by a dedicated 300 W PWM Class D amplifier.

What DSP presets are available on the S3H?
The S3H provides 6 parametric EQ bands, 5 storable preset memories, and a unique factory EQ preset that emulates the frequency response of ADAM Audio's S3A monitor, allowing direct sonic comparison between the two designs.
