The QSC AC-S6T is a compact 6.5-inch two-way loudspeaker from QSC's AcousticCoverage series, engineered to deliver consistent, wide-coverage sound for installed sound applications. This model features QSC's patented AcousticCoverage lens technology, which is designed to provide a uniform frequency response across a broad 130-degree horizontal dispersion pattern. Unlike conventional horns, this lens technology ensures that high frequencies are evenly distributed throughout the coverage area, minimizing the "hot spots" and drop-offs that can occur with traditional designs. This makes the AC-S6T an excellent choice for foreground music, speech reinforcement, and fill applications in spaces like retail stores, restaurants, conference rooms, and hospitality venues where even sound coverage is critical from various listening positions.

The loudspeaker is built around a 6.5-inch woofer with a high-temperature voice coil and a 1.4-inch titanium diaphragm compression driver. The integrated passive crossover is precision-tuned to optimize the performance of both drivers with the AcousticCoverage lens. For installation flexibility, it includes a built-in multi-tap transformer for 70V/100V operation, with several power tap settings, as well as an 8-ohm direct input mode. This allows integrators to easily match the speaker to the amplifier's output and balance levels within a distributed audio system. The enclosure is constructed from durable, mineral-filled polypropylene and features a paintable grille, allowing it to blend discreetly into its environment.

For system designers and installers, the QSC AC-S6T offers a reliable and sonically advanced solution for challenging coverage areas. Its wide, consistent dispersion reduces the number of speakers required to cover a given space evenly, simplifying system design and installation while improving the listener's experience. The combination of robust construction, flexible power options, and innovative acoustic technology makes this loudspeaker a versatile and high-performance component for a wide range of commercial sound installations.
