QSC AD-S6 Overview

The black AcousticDesign Series QSC AD-S6T is a pair of transformer-equipped 6.5" 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 6.5" weather-treated woofer and a 1" silk dome tweeter on a DMT waveguide, the AD-S6T offers even 105° conical coverage and improved off-axis response while providing a frequency range of 60 Hz to 20 kHz (-10 dB). The speaker is capable of handling 150W RMS and producing a peak maximum SPL of 116 dB.

The AD-S6T 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-S6T 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
