The JBL Control 426LP is a two-way coaxial ceiling loudspeaker equipped with a 6.5-inch woofer housed in a low-profile enclosure designed for installations with limited ceiling plenum space. It features integrated Coplanar Radial Boundary Integrator (CRBI) technology that delivers a 110° coverage angle with consistent sound dispersion, reducing on-axis peaks and off-axis dropouts to maintain uniform audio performance across the coverage area. The speaker includes a built-in transformer supporting both 70V/100V and low impedance operation, enabling adaptable use in various audio distribution systems.
