QSC AD-S4T AcousticDesign Series 4.5" 2-Way 50W Surface-Mount Loudspeaker, Black

Deliver clear, reliable audio for commercial, retail and security environments with the QSC AD-S4T surface-mount loudspeaker. This AcousticDesign 2-way speaker combines a 4.5" weather-treated woofer and 0.75" silk-dome tweeter with QSC’s Directivity Matched Transition (DMT) to provide uniform 120° coverage and intelligible voice reproduction—critical for paging, surveillance alerts and monitoring systems. Rated for 50W RMS power handling and up to 110 dB peak SPL, the AD-S4T handles foreground paging and background music with assurance.

Built for real-world installations, the sealed ABS enclosure, powder-coated grille and IP54 rating reduce upkeep and protect against dust and splashes. The X-Mount™ hardware speeds installation and keeps speakers aimed where you need them, while the onboard 70/100V low-saturation transformer and 8Ω bypass offer deployment flexibility across distributed audio or low-impedance networks. Integration is streamlined with advanced voicing filters via QSC Intrinsic Correction™ on Q-SYS or CXD amplifiers.

Ideal for retail stores, transit hubs, schools and security/surveillance setups—spec the QSC AD-S4T for dependable, pro-grade audio performance. Order or request CAD/BIM files to start your installation.
