QSC AD-S8T-BK 8” Surface Speaker

(70/100V / 8Ω Bypass Installation Speaker – 105° DMT™ Coverage, X-Mount™, Weather Input Cup, Black)

The QSC AD-S8T-BK is a professional 8-inch 2-way surface-mount installation speaker designed for high-output background and foreground audio in commercial and architectural environments. As part of the QSC AcousticDesign™ Series, it delivers powerful, full-range sound with excellent clarity and consistent coverage for medium to large installation spaces.

Equipped with DMT™ (Directivity Matched Transition) technology, the AD-S8T-BK provides a wide 105° conical coverage pattern, ensuring even sound distribution and smooth tonal balance across the listening area. This makes it ideal for applications requiring strong vocal clarity and music reinforcement with fewer speaker units.

The speaker supports both 70/100V constant-voltage systems and 8Ω bypass operation, giving installers maximum flexibility for distributed or low-impedance audio designs. It also includes the QSC X-Mount™ system for secure and adjustable installation, along with a weather-protected input cup for improved durability and safe wiring in demanding environments.

With its black finish, the AD-S8T-BK blends well into darker interiors and professional installations such as venues and performance spaces.
