Product Details

Overview

The black QSC AcousticDesign AD-S4T Loudspeaker is a surface mounted 70/100V, 4" two-way loudspeaker system, ideally suited for a wide variety of foreground and background sound reinforcement applications. The AD-S4T features a high-quality 4" weather-treated paper cone woofer on a 1" voice coil. It also has a 0.75" silk dome tweeter with a 0.75" voice coil. The consistent and even 120° axisymmetric (conical) coverage is achieved through DMT (Directivity Matched Transition), which matches the directivity patterns of the woofer and the high-frequency waveguide at the crossover point. The even and accurate frequency response of the AD-S4T is maintained even in 70/100V applications by use of a low-loss, low-saturation 30W transformer with selectable taps, including an 8-ohm bypass. The rotary selector is located on the back of the enclosure, protected by a weather grommet. Featuring a rugged ABS enclosure, sealed input panel cover, and powder-coated aluminum grille, the AcousticDesign surface-mounted speaker exceeds IEC60529 IP-54 ratings for dust and splash resistance.

The two-way surface-mount loudspeaker includes the X-Mount system for easy installation. 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. Voicing filter sets using QSC Intrinsic Correction techniques are obtainable via Q-Sys networked audio processing platforms, including CXD amplifiers (sold separately). For your system integration needs, complete EASE, CF2, CAD, and BIM files are available for download on the QSC website.
