The QSC AD-C6T is a high-performance, 6.5-inch two-way ceiling loudspeaker engineered for professional installed sound applications demanding both superior audio quality and reliable, consistent coverage. As part of QSC's AcousticDesign series, this speaker is designed for flush-mount installation in standard T-bar ceiling grids, making it an ideal choice for a wide range of commercial environments such as corporate offices, retail spaces, restaurants, hotels, and educational facilities. Its core design philosophy balances acoustic precision with practical installation features, providing integrators with a tool that delivers clear, intelligible sound while simplifying the deployment process in challenging architectural settings.

The speaker features a 6.5-inch mineral-filled polypropylene woofer paired with a 1-inch titanium dome compression driver, coupled to a wide-dispersion waveguide. This two-way coaxial design ensures precise time alignment and a coherent acoustic source, resulting in smooth frequency response and even coverage across the listening area. The integrated pivoting tweeter assembly allows installers to aim the high-frequency driver up to 15 degrees off-axis, enabling fine-tuning of coverage patterns to direct sound away from reflective surfaces or towards specific zones, thereby optimizing speech intelligibility and music reproduction within the space. The entire transducer system is housed in a rigid, resonance-resistant ABS composite back-can that minimizes coloration.

Constructed for durability and ease of installation, the AD-C6T features a paintable, low-profile grille that blends discreetly into ceiling tiles. The enclosure is designed with an integrated tile bridge and quick-connect terminals, allowing for rapid mounting and wiring without the need for external mounting hardware or backboxes in plenum spaces. It offers both low-impedance (8-ohm) and 70V/100V transformer-tapped operation, with multiple power tap settings accessible via a rotary switch, providing immense flexibility for system design. For integrators seeking a reliable, great-sounding ceiling speaker that combines advanced acoustics with installer-friendly features, the QSC AD-C6T represents a versatile and professional-grade solution.
