QSC AD-S4T Overview

The black AcousticDesign Series QSC AD-S4T is a pair of transformer-equipped 4.5" surface-mount loudspeakers supplied with award-winning X-Mount systems, making them suitable for 70/100V or 8-ohm operation in a variety of foreground and background music applications, whether installed in horizontal, vertical, wall, or ceiling deployments.

Outfitted with a 4.5" weather-treated woofer and a 0.75" silk dome tweeter on a DMT waveguide, the AD-S4T offers even 120° conical coverage and improved off-axis response while providing a frequency range of 68 Hz to 20 kHz (-10 dB). The speaker is capable of handling 50W RMS and producing a peak maximum SPL of 110 dB.

The AD-S4T utilizes a 4-pole Euroblock connector under a sealed input cover for easy wiring and protection from moisture. Featuring a rugged ABS enclosure and a powder coated aluminum grille, the AD-S4T boasts dust and splash resistance beyond IP54 ratings for worry-free operation indoors or outside.

Designed for foreground and background music sound reinforcement in restaurant, retail, audio visual, education, and large system ancillary support applications as well as in concourses, casinos, transportation terminals, and worship facilities
Supplied with award-winning X-Mount systems to enable easy installation in horizontal, vertical, wall, or ceiling deployments at a variety of angles with no slippage over time
