Q-SYS AC-MR4 Mud Ring For AC-C2T/AC-C4T Ceiling Speakers | 6-Pack

The Q-SYS AC-MR4 is a flanged mud ring bracket designed specifically for pre-installation of AC-C2T and AC-C4T ceiling speakers into drywall or plaster ceilings. It gives AV integrators the ability to rough-in speaker locations before finish surfaces are complete, keeping the installation timeline on track and eliminating the need to cut finished ceilings after the fact.

This approach is standard practice on commercial installs, corporate spaces, hospitality environments, and houses of worship where construction sequencing requires speaker placement to be locked in before drywall is taped and painted. Using the AC-MR4 at the rough-in stage protects the opening, maintains alignment, and simplifies the final speaker drop-in. Each box contains six mud rings, making it practical for multi-room deployments and reducing per-unit procurement overhead on larger projects.
