QSC AD-S8T-BK 8" 2-Way Surface Speaker, 70V with X-Mount, Black

The QSC AD-S8T AcousticDesign speaker offers integrators a premium quality installed sound solution where performance, coverage, and aesthetics are essential. This model features low-loss, low-saturation transformers with selectable taps, including an 8-ohm bypass. To enhance weather resistance, the rotary selector is located on the back of the enclosure, protected by a weather grommet. AcousticDesign speakers are easy to install and offering high weather resistance, AcousticDesign speakers provides integrators with a versatile install solution for a wide variety of foreground and background sound reinforcement applications. Consistent and even axisymmetric coverage is achieved through DMT (Directivity Matched Transition), which 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. 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. Installers will appreciate the award-winning X-Mount system included with each full-range AcousticDesign model. This ingenious mounting solution achieves unprecedented ease-of-installation in horizontal, vertical, wall, or ceiling deployments. Knurled surfaces at the pivot planes ensure the load will not drift or sag over time. Articulation marks allow pre-configuration of the X-Mount while on the ground with no special tools required. Once secure, the loudspeaker installs in seconds, allowing the installer to work safer, smarter, and faster with repeatable results. To further enhance performance and speed of install with optimum result, advanced voicing filter sets using QSC Intrinsic Correction techniques are obtainable using Q-Sys networked audio processing platforms, including CXD amplifiers for a complete QSC systems solution.
