Enhanced Coverage
The JBL Control 424C/T is a two-way coaxial ceiling loudspeaker, featuring a 4" woofer and integrated enclosure that is ideal for installation in most ceiling plenum spaces. Integrated CRBI™ technology provides 130° of consistent, full, rich sound to the listening area. 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. The JBL Control 424C/T includes a transformer to support both 70V/100V and low impedance applications. Priced as each, but packaged and sold only in pairs.
