The QSC AC-C6T is a high-performance 6.5-inch two-way ceiling loudspeaker designed for discrete, high-fidelity audio in commercial installed sound systems. Part of the AcousticCoverage series, this speaker is engineered for flush mounting in standard T-bar ceilings or solid ceilings, delivering wide, even sound dispersion for background music, paging, and voice reinforcement in environments such as retail stores, offices, restaurants, hotels, and educational facilities. Its low-profile, round enclosure is constructed from durable, mineral-filled polypropylene and features a paintable grille that allows it to blend seamlessly with ceiling tiles, maintaining a clean architectural aesthetic. The speaker is designed for easy installation with a simple dog-leg mounting system that secures it firmly in place.

The acoustic performance of the AC-C6T centers on its 6.5-inch woofer and 1-inch pivoting tweeter, managed by a precision passive crossover. The pivoting tweeter is a key feature, enabling installers to aim the high-frequency energy away from reflective surfaces or toward specific listening areas after installation, optimizing clarity and coverage. This speaker operates in 70V, 100V, or 8Ω low-impedance modes, providing exceptional flexibility for system designers to integrate it into virtually any commercial audio topology. Multiple selectable power taps on the constant-voltage transformer allow for precise power matching to the acoustic requirements of the space, ensuring optimal performance and headroom.

Built with QSC's reputation for reliability, the AC-C6T includes built-in protection for long-term durability in continuous-use applications. Its combination of wide dispersion, adjustable high-frequency directionality, and installer-friendly design makes it a versatile and trusted choice for achieving consistent, intelligible sound coverage in distributed audio systems. For consultants and integrators seeking a sonically transparent, aesthetically unobtrusive, and highly adaptable ceiling speaker solution, the QSC AC-C6T offers a professional-grade component that balances performance with practicality.
