Q-SYS AcousticDesign AD-S4T White Surface Speaker
QSC AcousticDesign AD-S4T White Surface Speaker
AcousticDesign surface loudspeakers are designed for clarity and presence -these loudspeaker systems deliver pristine audio reproduction for installations requiring a refined audio experience. Models ship complete with the award winning X-Mount system and weather input cover. Consistent and even axisymmetric coverage is achieved through Directivity Matched Transition (DMT), a QSC innovation that matches the directivity patterns of the woofer and the high-frequency waveguide at the crossover point. The result is a coherent transition between transducers and improved off-axis response. The AD-S4T features a low-loss, low-saturation transformer with selectable taps, including an 8ohm bypass.
To enhance weather resistance, the rotary selector is located on the back of the enclosure, protected by a weather grommet. With rugged ABS enclosures, sealed input panel covers, and powder-coated aluminum grilles for weather resistance, the AcousticDesign surface mounted series exceed IEC60529 IP-54 ratings for dust and splash resistance.
