QSC AD-S12 12" Two-Way Surface Mount Loudspeaker

  • $920.00

The QSC AcousticDesign™ AD-S12 is a surface mounted low impedance, 12” twoway 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-S12 features a high quality 12" weather treated paper cone woofer on a 2.5" 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 75° 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. 

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-S12 also includes M10 fittings for optional yoke mount (YMS12) 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) or white (RAL 9010) and may be painted to match any decor.
