Jbl Professional JBLC447C/T-U Ceiling Loudspeaker 6.5 in

Product Description

The JBL PROFESSIONAL JBLC447C/T-U is a two-way coaxial ceiling loudspeaker from the Control 400 Premium Coverage Series, designed for commercial and institutional audio distribution installations. It houses a 6.5-inch woofer paired with a conical Radiation Boundary Integrator (RBI) that delivers constant-directivity coverage across a wide listening area. The integrated enclosure is sized for installation in standard ceiling plenum spaces, and the unit supports both 70V/100V distributed audio systems and low-impedance direct-drive applications. Licensed LVAS contractors and systems integrators are the primary installers of this loudspeaker.

The JBLC447C/T-U is suited for commercial interiors, hospitality venues, retail environments, houses of worship, and corporate facilities where consistent, evenly distributed sound coverage is required. The captive dogear mounting hardware accommodates a range of ceiling thicknesses, making it adaptable across new-construction and retrofit scenarios. The full-face magnetic grille is paintable, allowing the loudspeaker to blend into finished ceiling surfaces. Optional black and square grilles are available for additional customization. This model is part of the JBL Control 400 Premium Coverage Series and operates across both distributed and low-impedance wiring topologies.
