QSC AD-S6T AcousticDesign Surface Mount Loudspeaker
The AD-S6T scales up the AcousticDesign surface-mount platform to a 6.5 inch weather-treated paper cone woofer and a 1 inch horn-loaded silk dome tweeter, adding real headroom for larger rooms, patios, and courtyards. DMT waveguide loading keeps 105 degree conical coverage even and consistent, matched tonally to the rest of the AcousticDesign ceiling, surface, and pendant family.
The included X-Mount system installs in horizontal, vertical, wall, or ceiling orientations with no slip over time, and a 60-watt low-saturation 70/100V transformer with an 8 ohm bypass is set from a weather-grommeted rotary selector on the back. Rugged ABS enclosures and powder-coated aluminum grilles exceed IEC60529 IP-54 for dust and splash resistance, indoors or out.
