The JBL Control 328CT is a 250-watt coaxial ceiling loudspeaker designed with a point source configuration and an integrated 70V/100V transformer. It features an 8" low-frequency cone that also functions as a waveguide for the high-frequency output. A specially designed metal throat ensures a smooth transition to the horn, preventing unwanted high-frequency beaming and delivering uniform 120° broadband coverage with authentic coaxial performance.
