The QSC AcousticDesign™ AD-S4T is a surface mounted 70/100V, 4.5" 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-S4T features a high quality 100 mm [4 in] weather treated paper cone woofer on a 25 mm [1 in] voice coil. A carefully selected 19 mm [.75 in] silk dome tweeter with a 19 mm [.75 in] voice coil perfectly matches the sensitivity and performance of the woofer for outstanding full-range reproduction.

Consistent and even 120° 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-S4T is maintained even in 70/100V applications by use of a low-loss, low-saturation 30-watt transformer with selectable taps, including an 8O bypass. To preserve 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 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 via the Q-SYS Platform including CXD Series amplifiers for a complete QSC systems solution.
