The JBL Control 426C/T-LS is a two-way coaxial ceiling loudspeaker featuring a 6.5-inch woofer housed within an integrated enclosure designed for installation in standard ceiling plenum spaces. The loudspeaker is UL1480 certified for life safety applications and includes a built-in transformer supporting 70V/100V and low impedance configurations. It employs Coplanar Rotational Bandwidth Integration (CRBI) technology to deliver a consistent 110° sound coverage pattern, aiming to provide uniform acoustic dispersion across the listening area. The unit incorporates redesigned terminal covers with both top and side cable entry ports, secured by captive hand-screws, and a captive dogear mounting system compatible with a wide range of ceiling thicknesses.
