The QSC AD-S12-WH AcousticDesign Series 12-Inch 2-Way 300W Surface-Mount Loudspeaker (Single, White) is a passive, 8-ohm loudspeaker designed for foreground and background music applications. Featuring a 12-inch weather-treated woofer, a 1-inch exit compression driver, and QSC's Directivity Matched Transition (DMT) technology, it delivers consistent sound coverage for commercial and professional installations.
The AD-S12-WH provides 75-degree conical coverage, a frequency range of 52 Hz to 20 kHz at -10 dB, and a peak maximum SPL of 126 dB. Its DMT waveguide is designed to improve off-axis response and create a consistent transition between the low- and high-frequency drivers.
The included X-Mount system supports flexible horizontal and vertical positioning for wall or ceiling installations. Additional mounting options are available through separately sold M10-compatible accessories.
A rugged ABS enclosure, powder-coated aluminum grille, and sealed input cover help protect the speaker in demanding indoor and outdoor environments. The 4-pole Euroblock connector supports speaker input and loop-through wiring.
For optimized system performance, QSC Intrinsic Correction voicing filters are available through compatible Q-SYS processing or CXD amplifier platforms, sold separately.
