QSC AD-S6 AcousticDesign 6.5-Inch Surface Mount Speaker

The AD-S6 from QSC’s AcousticDesign series is a two-way surface-mounted loudspeaker. It’s ideal in foreground and background sound reinforcement situations utilizing 70/100V or 16Ω bypass configurations. The AD-S6 includes a 6.5” weather-treated paper cone woofer with a 1.5" voice coil and a 1" silk dome tweeter that perfectly matches the sensitivity and performance of the woofer for outstanding full-range reproduction. Among its many features, Intrinsic Correction™ voicings can be deployed to optimize installation and performance. Ideal for distributed systems, its 16-ohm impedance equips you for optimal sonic performance without needing a transformer.

Achieve coherent transition between transducers with Directivity Matched Transition™ (DMT), QSC’s design philosophy where the high-frequency waveguide is matched to the natural conical behavior of the woofer at the crossover point. DMT’s improved off-axis power response results in consistent 105° conical coverage.

Install your AD-S6 safely, securely, and swiftly. Each AcousticDesign model comes with the award-winning X-Mount™ system for simple and easy wall or ceiling installation in either horizontal or vertical orientations. The pivot planes feature knurled surfaces to prevent drifting or sagging over time, while articulation marks allow you to preconfigure the mounting system on the ground—without requiring special tools. In addition to rugged ABS enclosures characteristic of AcousticDesign speakers, surface-mount models boast sealed input panel covers and weather-resistant powder-coated aluminum grilles, allowing them to exceed IEC60529 IP-54 ratings for dust and splash resistance.

AcousticDesign speakers are free of obtrusive branding. They’re available in black or white, as well as paintable to match any décor.
