The JBL MTC-24MR is a dedicated mud ring construction bracket designed for the secure and compliant rough-in installation of the JBL Control 24C and similar ceiling loudspeakers during new construction or major renovation projects. This heavy-duty mounting accessory serves as a critical structural interface, installed directly to the building's framing before the application of drywall or other ceiling finishes. Its primary function is to provide a rigid, code-approved support platform that ensures the loudspeaker is perfectly positioned and anchored, facilitating a professional and permanent installation that meets safety standards and ensures long-term reliability in commercial and architectural sound systems.

Constructed from robust, galvanized steel, the mud ring is engineered to be nailed or screwed securely to ceiling joists or other structural members. Its design is precisely tailored to the dimensions and mounting requirements of the Control 24C loudspeaker back-can, guaranteeing correct alignment and a seamless fit once the ceiling is finished. The open-frame design allows electricians and audio integrators easy access to run and connect speaker cables during the rough-in phase, streamlining the workflow and ensuring all wiring is correctly in place before the drywall is installed.

This accessory is an essential component for professional integrators and contractors who require a manufacturer-supported, structured approach to installing ceiling speakers in demanding environments. By providing a dedicated structural mounting point, the MTC-24MR mud ring ensures the final installation is not only acoustically optimal but also mechanically secure, preventing sagging or movement and contributing to the overall durability and quality of the installation. It represents the professional practice of addressing the structural integration of audio components with the same rigor as their electronic performance.
