The JBL Control 447LP, part of the flagship Control 400 Premium Coverage Series, is a two-way coaxial ceiling loudspeaker featuring a 6.5” woofer, conical RBI™, and a low-profile enclosure that is ideal for applications where ceiling plenum space is restricted.

Featuring JBL’s proprietary conical Radiation Boundary Integrator® (RBI™) technology, the Control 447LP achieves constant directivity coverage, ensuring that listeners can enjoy an especially smooth sound character that remains extremely consistent, clear, and pleasant across a wide coverage area.

Control 400 Series ceiling speakers boast thoughtfully engineered mounting features to enhance safety, efficiency, and repeatability. Terminal covers allow for convenient top or side cable entry and are secured effortlessly with captive hand-screws. The reliable captive dogear design accommodates a variety of ceiling thicknesses, ensuring versatility for any environment.

All models embrace design elements tailored for modern interiors. The included full-face magnetic grille is paintable for seamless integration into any decor, while available black and square grilles provide added customization. Additionally, the Control 447LP supports both 70V/100V and low impedance applications.
