CONTROL 424LP is a two-way coaxial ceiling loudspeaker featuring a 4-inch woofer within a low-profile enclosure designed for restricted ceiling plenum spaces. It integrates Coplanar RBI (CRBI) technology to provide a uniform 130° coverage angle. The loudspeaker includes a full-face magnetic baffle and offers optional black and square baffle accessories. The enclosure incorporates redesigned terminal covers with both top and side cable entry ports, secured by captive hand-screws allowing tool-free installation. The captive dogear mounting system accommodates a wide range of ceiling thicknesses.
The loudspeaker supports both 70V/100V and low impedance applications via an integrated transformer. Safety tethers attach the baffle to the baffle for secure mounting.
