QSC AD-S4T

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.
