Adam Audio S3X-H Powered Studio Monitor




Highly evolved 3-way studio monitor with two horizontally arranged 7.5″ bass drivers.

The S3X-H is the most successful model of the SX-Series as the highly evolved successor of ADAM’s very popular S3A. Designed as a 3-way speaker, it includes two horizontally arranged 7.5″ bass drivers, one 4.5″ midrange speaker and the characteristic ADAM X-ART tweeter. The cone woofers are driven by three powerful 250W PWM amplifiers that enable the S3X-H to provide amazing dynamic bass performance. Even if they are classified as midfield monitors due to their power capabilities, S3X-H is also ideal for reproducing spatial depth at shorter listening distances.

The top-class X-ART driver produces brilliant and transparent high frequencies. The three-dimensional spatial imaging and rapid, powerful midrange/bass response make the S3X-H extremely musical, dynamic and colorful. The S3X-H also provides clear representation of minimal changes in your mix and the corresponding sonic consequences. Long working sessions with the S3X-H are not fatiguing to the ear. Quite the contrary: the authenticity and brightness of this exceptional monitor enhances the creative process of musicians and producers around the world.

Powerful amplifiers and HexaCone woofers – the perfect combination
High-performance PWM amplifiers drive all of the woofers in SX-Series monitors. Due to their high efficiency of over 90%, these amplifiers have less power loss and are thus more loadable and durable than classic A/B amplifiers. They are also more broadband with additional sonic benefits in the treble range. ADAM has developed a special low-noise 50W amplifier with a flat frequency response up to 300 kHz to drive the X-ART tweeter. In conjunction with the high-efficiency tweeters, this enables the SX-Series models to produce both accurate and effortless high-frequency reproduction.

The cone speakers in the SX monitors are all made from HexaCone, an aramid-plastic core with honeycomb structure coated on both sides with Kevlar. This ensures maximum strength with minimum weight, resulting in a superior dynamic response with self-resonances of the diaphragm eliminated from the audible range. The advantage of combining HexaCone woofers with an X-ART tweeter and PWM amplifiers is outstanding dynamic performance and high sound pressure levels.

X-ART reveals the finest sonic details
Every model of the SX-Series features ADAM’s unique ‚hand-made in Berlin’ tweeter with our proprietary X-ART technology. In addition, the main monitors (S5X-H, S5X-V, S6X and S7A Mk2) are also equipped with X-ART midrange drivers. The precise transient response as well as the driver’s ability to reproduce the finest sonic details make ADAM monitors uncompromising and effective tools. SX cabinets are built with generously rounded edges and a durable plastic coating. The former minimizes distracting reflections while the latter provides extra protection for everyday use in the studio.

Extensive room adaptive options
A variety of control options are available in the SX-Series models for extensive adjustments to room acoustics. The S1X features low and high shelving EQs as well as the tweeter gain and volume control. Models S2X through S5X also feature a front-mounted control panel. In addition to a standby switch, two LEDs to indicate clipping and the status of the optional D/A-converter are located here. The S6X and S7A Mk2 models have an even more extensive set of available controls.
