Sale price$680.00


The black AcousticDesign Series QSC AD-S8T is a transformer-equipped 8" surface-mount loudspeaker supplied with the award-winning X-Mount system, making it 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 an 8" weather-treated woofer and a 1" exit compression driver with a DMT waveguide, the AD-S8T offers even 105° conical coverage and improved off-axis response while providing a frequency range of 55 Hz to 20 kHz (-10 dB). The speaker is capable of handling 200W RMS and producing a peak maximum SPL of 119 dB.

The AD-S8T 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-S8T 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
