The S4X models
The S4X monitors are not just an improved versions of the famous and highly acclaimed S4A but an evolutionary development. Like their predecessors, they have been designed for medium size control rooms. Given their excessive power, the S4X are also capable of working in larger environments. Because both S4X models have identical tweeters and midrange drivers handling frequencies above 350Hz, any combination of either model will integrate perfectly in a 5.1 or 7.1 installation.
X-ART & newly developed broadband amplifier
All models of the SX-Series are equipped with the new X-ART tweeter. The X-ART tweeter has a 4dB higher efficiency, a 3dB higher maximum sound pressure level, and an increase in frequency response up to 50kHz. The newly designed broadband A/B amplifier has been developed by ADAM to perfectly match the needs and capabilities of the X-ART tweeter. The entire range of sound can be heard as never before.
New HexaCone woofers
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.
Optional digital input and magnetical shielding
All SX-models (except the S1X) can be optionally retrofitted with a 24 bit/192 kHz D/A Converter featuring an AES/EBU (XLR) and a SPDIF (RCA) inputs as well as a R/L/Mono switch.
All models can optionally be magnetically shielded.
The S4X-V has been designed for vertical installation. This reference monitor features the same X-ART and 6" HexaCone midrange as the S4X-H allowing for almost identical tonal characteristics of both speakers. This allows combinations of the different versions in bigger multi-channel applications without tonal imbalance.
Furthermore, the S4X-V features a newly developed 12" HexaCone woofer. This driver, with electronic correction, has been designed for optimal results in a bass-reflex cabinet. An exceptionally long 3" voice coil coupled with a very strong and highly effective magnet system provides for powerful, yet never overemphasized bass reproduction.
Improperly designed larger monitors are always at risk of compromising the overall sound with bass reproduction that is too intense. 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 (28Hz at -3dB 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.
ADAM has developed an innovative front panel with sophisticated controls. These controls allow the user to adapt the speakers to the soundroom with high precision.
Apart from the standby-button, there are two controls for the input sensitivity, two for the bass section and two more for the high frequencies.
