The QSC AC-S6T-BK is a compact 6.5-inch two-way loudspeaker from the AcousticCoverage series, engineered for high-fidelity, wide-dispersion sound reinforcement in commercial installed sound applications. Designed for both surface mounting and in-ceiling installation, this speaker provides a versatile solution for background music, paging, and voice reinforcement in environments such as retail stores, restaurants, conference rooms, hotels, and houses of worship. Its trapezoidal, low-profile enclosure is constructed from durable, mineral-filled polypropylene and finished in a black textured coat, allowing it to blend discreetly into architectural settings whether mounted on a wall, corner, or ceiling. The paintable grille offers further aesthetic customization to match interior décor.

The loudspeaker system integrates a 6.5-inch woofer and a 1-inch tweeter, coupled via a precision crossover network. It is engineered to deliver a smooth, balanced frequency response with exceptional clarity in the critical midrange for speech intelligibility, while the pivoting tweeter design allows for precise aiming of high frequencies to optimize coverage and minimize reflective surfaces. This feature is particularly valuable in compensating for less-than-ideal speaker placements. The AC-S6T operates in 70V, 100V, or 8Ω low-impedance modes, providing installers with maximum flexibility to integrate it into virtually any commercial audio system design, with selectable power taps for constant-voltage systems enabling precise power matching to the zone's requirements.

As part of QSC's commitment to performance and reliability, the AC-S6T includes built-in protection to safeguard its components. Its combination of wide dispersion, versatile mounting, and installer-friendly features makes it a dependable choice for creating even, high-quality sound coverage in challenging acoustic spaces. For system integrators seeking a sonically transparent, aesthetically subtle, and highly adaptable loudspeaker for distributed audio systems, the QSC AC-S6T-BK offers a professional and proven solution.
