Sale price$896.00


Sold as a pair, 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.

  • 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
  • Supplied with award-winning X-Mount systems to enable easy installation in horizontal, vertical, wall, or ceiling deployments at a variety of angles with no slippage over time
  • 6.5" weather-treated paper cone woofer with a 1.5" voice coil and a 1" silk dome tweeter that matches the sensitivity and performance of the woofer for optimal full-range reproduction
  • Consistent and even 105° conical coverage is achieved through DMT (Directivity Matched Transition), a QSC innovation which matches the directivity patterns of the woofer and the high-frequency waveguide at the crossover point, resulting in a coherent transition between transducers and improved off-axis response
  • Rugged ABS enclosure and powder coated aluminum grille
  • Exceeds IP54 ratings for dust and splash resistance
  • Low-saturation, low-loss 70/100V transformer with 8-ohm bypass
  • Rear-panel rotary tap selector is protected by a weather grommet
