The S4X-H midfield monitor combines the X-ART tweeter with a 5“ HexaCone midrange and two redeveloped 9“ HexaCone woofers. Each of the woofers and midrange drivers are driven by a 250 W ICE module. To allow the X-ART tweeter to extend to its highest frequencies, it is combined with a unique ADAM Audio A/B amplifier. This unique amplifier has ultra low distortion and an immense internal bandwidth of more than 1MHz. Combine this amplifier with the X-ART tweeter and you get a fascinating sound that is effortless and of highest resolution. As in all ADAM Audio designed speakers, both versions of the S4X have been designed to combine both the power and volume of the bass (28 Hz at -3 dB point) with the highest possible precision. Combine this with the transparent high and midrange frequencies of the S4X and this will give an engineer a new quality level of control and performance for larger rooms. The new HexaCone woofers are designed with larger and longer voice coils that deliver more linear excursion for higher SPL max. values. A stronger magnetic structure is added as well for an optimum in efficiency and accuracy.
