The QSC AC-S4T-BK is a 4-inch two-way surface-mount loudspeaker from the AcousticCoverage Series, finished in black for wall or ceiling mounting where recessing isn't possible. It pairs a polypropylene woofer with an aluminum-dome tweeter to deliver clear, full sound with wide 130-degree conical coverage, making it well suited to background music and paging in retail, hospitality, offices and public areas. A multi-tap transformer supports 70V and 100V distributed audio systems, with an 8-ohm bypass for low-impedance use, and an included mounting bracket allows flexible aiming. The rugged enclosure and black finish blend into modern interiors while standing up to everyday commercial use.
