    The QSC AcousticDesign AD-S8T is a surface mounted 70/100V, 8" two-way loudspeaker system, ideally suited for a wide variety of foreground and background sound reinforcement applications. AcousticDesign series offers integrators a premium quality installed sound solution where performance, coverage, and aesthetics are paramount. Combined with unprecedented ease-of-installation and high weather resistance, the AcousticDesign series provides integrators a versatile and confident install solution. The AD-S8T features a high quality 8" weather treated paper cone woofer on a 2" voice coil. A carefully selected 1" exit, 1.4" compression driver perfectly matches the sensitivity and performance of the woofer for outstanding full-range reproduction. Consistent and even 105° axisymmetric (conical) coverage is achieved through DMT (Directivity Matched Transition), a QSC innovation 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. The even, accurate frequency response of the AD-S8T is aided by a 60-watt low-loss, low-saturation transformer with selectable taps, including an 8Ω 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. Installers will appreciate the award-winning X-Mount system included with each fullrange 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 preconfiguration 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. The AD-S8T also includes M10 fittings for optional yoke mount (YMS8T) or shoulder eybolt (M10 Kit-C) accessories for installation versatility. 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. The AcousticDesign series feature a stylish appearance free of obtrusive logo adornments for aesthetically sensitive installations. AcousticDesign surface loudspeakers are available in QSC standard black (RAL 9011) and may be painted to match any decor.
