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. 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.
