JBL MTC-Pack for Control 447C/T New Construction Bracket – 6

The JBL MTC-447NC is a professional-grade new construction bracket designed specifically for the Control 447C/T ceiling speaker from JBL’s flagship Control 400 Premium Coverage Series. This bracket ensures a secure, efficient, and repeatable installation in new construction or retrofit projects, providing a reliable foundation for high-performance JBL ceiling loudspeakers.

The Control 447C/T itself is a two-way coaxial ceiling speaker featuring a 6.5-inch woofer and a 1-inch soft-dome tweeter, integrated within an enclosure optimized for most ceiling plenum spaces. JBL’s proprietary conical Radiation Boundary Integrator® (RBI™) technology ensures constant directivity coverage, delivering exceptionally smooth, clear, and consistent sound across a wide listening area. When paired with the MTC-447NC bracket, the installation process becomes more efficient and repeatable, with reliable dogear mounting points that accommodate a range of ceiling thicknesses.

Engineered for professional installers, the MTC-447NC bracket simplifies placement and ensures the Control 447C/T is correctly aligned and supported. Terminal covers provide flexible top or side cable entry, and the included full-face magnetic grille—paintable in white or customized with optional black and square accessory grilles—offers seamless integration with modern architectural designs. Each bracket is IP33 rated for durability in protected environments and meets UL and NFPA safety standards for air-handling spaces.

Sold as a 6-pack, the MTC-447NC is ideal for outfitting multiple speakers in new construction projects, ensuring secure mounting, consistent alignment, and professional-quality results. This bracket is an essential accessory for any installation requiring JBL’s renowned sound quality and dependable, repeatable installation methods.
