The AD-S5T 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-S5T features a 5.25 weather-treated paper cone woofer with a 1.5" voice coil and a .75" 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.
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.
Maintain an accurate frequency response even in 70/100V applications. The AD-S5T’s low-loss, low-saturation 60W transformer offers selectable taps (including 8Ω bypass) and incorporates a rotary selector on the enclosure back, protected from the elements by a weather-resistant grommet. 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.
Install your AD-S5T 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.
AcousticDesign speakers are free of obtrusive branding. They’re available in black or white, as well as paintable to match any décor. The magnetic grille has a removable logo ideal for non-branded installations.
