Description
The JBL Control 328CT is a high-performance coaxial point source ceiling loudspeaker engineered to deliver exceptional next-generation audio performance. It is designed for professional and commercial installations where wide coverage, clear speech, strong vocals, and extended music response are required.
The Control 328CT features a 200 mm / 8-inch woofer with a Kevlar-reinforced cone and a 25 mm / 1-inch compression driver, delivering excellent clarity and smooth sound reproduction. Its consistent 120° broadband pattern control covers an extremely large listening area.
The speaker uses a shaped mounting baffle that provides the pattern control of a 300 mm / 12-inch horn from a compact 200 mm / 8-inch driver. With 250 W power handling, very high sensitivity, and an advanced high-slope crossover network, the Control 328CT delivers strong SPL capability with smooth and natural midrange performance. It also includes an integrated transformer for 70V/100V distributed audio systems.
