The JBL Control 424LP is a two-way coaxial ceiling loudspeaker, featuring a 4” woofer and a low-profile enclosure that is ideal for applications where ceiling plenum space is restricted. Integrated CRBI™ technology provides 130° of consistent, full, rich sound character that closely matches that of the Control 424C/T. A full-face magnetic grille blends seamlessly with modern decors and optional black and square grilles are available. Mechanical improvements include redesigned terminal covers with top and side cable entry ports and an extremely reliable new dogear design that works with a wide range of ceiling thicknesses. Like all Control 400 Enhanced Coverage models, the Control 424LP includes a transformer to support both 70V/100V and low impedance applications.
