Product Overview
The QSC AD-C305BG-BK is a zero-bezel black grille kit for QSC AD-C6TLP-ZB low-profile ceiling loudspeakers, supplied in a 10-pack for multi-room and large-zone projects. Its trimless, black-finished design lets installed ceiling speakers recede into architecturally sensitive interiors while keeping acoustic output unobstructed. Specifying the AD-C305BG-BK zero-bezel grille is a straightforward way to match QSC AcousticDesign ceiling speakers to dark or detailed ceilings in commercial and high-end residential spaces.
Product Description

The AD-C305BG-BK replaces the standard trim ring on the QSC AD-C6T-LPZB with a flush, frameless black grille for a clean ceiling line with no visible bezel. The black finish suits dark ceilings, exposed-structure interiors, and venues where loudspeakers should stay visually discreet. Each order is packaged and priced as a 10-pack, so quantities must be entered in multiples of ten, which fits boardrooms, retail, hospitality, and worship installations that deploy many ceiling speakers. Integrators standardizing on QSC AcousticDesign ceiling speakers can also pair these grilles with the QSC AD-C6T-ZB family for a consistent trimless look across a space.
