## Overview

The QSC AD-S4T is a high-performance 4.5-inch surface-mount speaker designed for versatile installation in both commercial and residential settings, delivering exceptional audio quality and robust power handling.

## Description

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.
