QSC AD-C6T-ZB-WH – AcousticDesign 6.5-Inch Zero-Bezel Ceiling Speaker (Pair, White)

Product Overview

The QSC AD-C6T-ZB-WH is a 6.5-inch two-way, zero-bezel ceiling speaker from the AcousticDesign Series, sold as a white pair. This trimless commercial ceiling loudspeaker delivers foreground and background sound on 70V/100V distributed lines or a 16-ohm bypass, with a sleek flush appearance for hospitality, corporate, retail, and education spaces. Its consistent voicing matches the wider AcousticDesign family for clean multi-zone deployments.

Product Description

The AD-C6T-ZB combines a 6.5-inch paper cone woofer with a 0.75-inch aluminum dome tweeter in a bass-reflex enclosure, delivering full-range clarity from 65 Hz to 20 kHz. A DMT (Directivity Matched Transition) waveguide keeps the high-frequency pattern matched to the woofer for even coverage across the listening area. The integrated transformer offers selectable 70V/100V taps plus a 16-ohm bypass, so integrators can drop it into distributed-audio designs or drive it directly, and Intrinsic Correction voicings are available through the Q-SYS Platform for plug-and-play tuning with QSC networked amplifiers.

Installation is handled by three double-stepped dog-ear clamps, a snap-fit magnetic grille, and a removable conduit cover plate for pre-install wiring. The speaker shares its tonal character with surface and pendant AcousticDesign models for blended systems. For a shallower plenum fit, see the QSC AD-C6T-LPZB-WH low-profile version, or step down to the QSC AD-C4T-LPZB-WH 4.5-inch model. A black-bezel finish is available with the AD-C245BG-BK black grille.
