The QSC LLC AC-MR6 is a mud ring accessory designed for use with compatible in-ceiling speaker installations. Mud rings, also called remodel rings or plaster rings, provide a clean, flush mounting surface when installing speakers into drywall or finished ceilings. This type of accessory is typically installed by low-voltage integrators, AV technicians, or electricians during rough-in or trim-out phases of a commercial or residential audio installation. The AC-MR6 is sold as a single unit and supports a professional-grade finish on speaker cutouts.
Mud rings are used in ceiling speaker installations where a recessed mounting frame is needed to sit flush against drywall, plaster, or drop-ceiling tile. This accessory is appropriate for commercial AV buildouts, boardrooms, retail spaces, hospitality venues, and residential whole-home audio systems. It provides a stable mounting interface that supports clean speaker alignment and a finished appearance at the ceiling plane.
Designed as an OEM-style accessory for use with compatible QSC LLC in-ceiling speaker models requiring a mud ring mounting solution. Consult the speaker installation documentation to confirm fitment before ordering.
Installation is typically performed by a low-voltage AV technician or licensed electrician. Power down all associated audio and low-voltage circuits before beginning work at the ceiling. Follow local building codes and any applicable NEC low-voltage wiring guidelines when running speaker cable through the ceiling cavity. Do not force the ring into an undersized cutout, as this may damage the ceiling surface or compromise the mounting.
