JBL Professional Control 400 Enhanced Coverage Ceiling Speakers

The JBL Control 400 Enhanced Coverage Series represents the next generation of excellence from the most trusted name in ceiling loudspeakers. As the successor to the iconic JBL Control 20 Series ceiling loudspeakers, known for their impeccable versatility and reliability, the Control 400 Enhanced Coverage Series extends that legacy with superior sonic performance, improved conical coverage, enhanced installation features, and a more modern aesthetic.

Adapted from renowned JBL tour sound technologies, JBL Professional introduces its latest iteration of Radiation Boundary Integrator (RBI) technology: the Coplanar RBI™, or CRBI™. This technology provides an especially smooth sound character that remains consistent, clear, and pleasant across a wide coverage area. This enhanced coverage results in more consistent levels and can lead to fewer required speakers and amplifier channels, and ultimately, significant project savings.

Each model in the Control 400 Enhanced Coverage Series includes an all-new, full-face magnetic grille that blends seamlessly with modern decors. The supplied white grille can be painted to match any application decor. Optional black and square grilles are also available.

Per JBL’s longstanding commitment to installer-centric design, the Control 400 Enhanced Coverage Series includes a variety of mounting enhancements to improve installation repeatability and safety while reducing installation time. Terminal covers provide both top and side cable entry ports and can be secured without tools thanks to captive hand-screws. The captive dogear design is extremely reliable and works with a wide range of ceiling thicknesses. Additionally, all Control 400 Enhanced Coverage models include transformers to support both 70V/100V and low impedance applications.

There are six models in the Control 400 Enhanced Coverage Series to facilitate the design of high-quality audio experiences in a wide range of environments and applications. The core models are the Control 426C/T and the Control 424C/T, two-way coaxial ceiling loudspeakers with 6.5-inch and 4-inch woofers, respectively. For applications where ceiling plenum space is limited, low-profile versions of those models, the Control 426LP and Control 424LP, are available. The Control 426C/T-LS has been certified to the UL1480 Standard, expanding application possibilities into life-safety designs. Finally, the Control 419CS/T is a high power, low distortion 8-inch in-ceiling subwoofer that augments any design that requires extended low-end performance.

Common Applications

The JBL Control 400 Enhanced Coverage Series is ideal for retail stores, corporate offices, education spaces, transit spaces, and any other application where a ceiling speaker with powerful performance and a refined look is desired.
