QSC AD-S8T

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.
