JBL Control 321CT 12″ Coaxial Ceiling Loudspeaker with HF Compression Driver

JBL Control 321CT 12 in. Coaxial Ceiling Loudspeaker

The JBL Control 321CT 12 in. Coaxial Ceiling Loudspeaker has been designed to provide next-generation performance in a coaxial point source ceiling loudspeaker. It features a 300 mm (12 in) woofer with Kevlar-reinforced cone and a 50 mm (2 in) voice coil, paired with a 25 mm compression driver to deliver clear, articulate speech and extended frequency response for music. Its consistent 90° broadband coverage ensures uniform sound across the listening area, while the advanced high-slope crossover network maintains smooth and natural midrange output.

With 250 W power handling and high sensitivity, the Control 321CT produces high SPL output suitable for commercial and professional installations. The speaker includes a ported baffle pre-attached with the transformer integrated for 70V/100V systems, while optional accessories such as the MTC-300BB12 backbox and MTC-300T150 transformer provide installation flexibility. The metal baffle with pre-mounted driver, ported design, and dual mounting system ensure a secure and reliable installation, while the formed steel and MDF-lined backcan enhances bass response and minimizes resonance. Ideal for speech, background music, and full-range audio applications, the JBL Control 321CT offers precise, powerful, and professional-grade ceiling sound performance.
