The horizontally designed S4X-H midfield monitor combines the X-ART tweeter with a 6" HexaCone midrange driver and two highly developed 9“ HexaCone woofers. A 250 Watt PWM amplifier drives each the woofers and midrange speaker, while the proprietary ADAM A/B amplifier powers the high-frequency range. The A/B amplifier’s minimum distor-tion and broadband features in conjunction with the X-ART tweeter result in a bright, contoured sound with no dynamic stress.

Larger monitors tend to compromise the overall sound with too much bass. Both S4X versions connect power and volume of the lower bass frequencies (the -3 dB point being at 28 Hz) with absolute precision, a clean midrange and effortless, highly precise transient reproduction. This makes accurate control of recorded material possible in larger control rooms.

The S4X-H is designed for medium-sized rooms, although it is able to fill larger rooms with adequate levels because of its power capabilities. Due to their technical specifications which closely follow the recommendations of the IRT (German Institute for Broadcast Technology), supreme sound quality and high reliability, these monitors are particularly suitable for broadcast and TV applications but can also be found in numerous major recording studios.
