12 in. Coaxial Ceiling Loudspeaker with HF Compression Driver
The JBL Control 321C is a passive 12" coaxial ceiling speaker designed for voice amplification and foreground music reproduction in waiting rooms, offices, retail stores, and restaurants. When driven by a low-impedance power amplifier (available separately), this 2-way speaker provides a long-term power capacity of 250W (1000W peak). The Control 321C is equipped with a durable 12" Kevlar-reinforced cone and a titanium-diaphragm compression driver, yielding an extended frequency response of 47 Hz to 16 kHz.
The cone, which also serves as a waveguide, results in reliable 90° broadband coverage while the built-in crossover network ensures proper frequency distribution to the speaker components. A removable locking connector with screw-down terminals ensures simple wiring for the input and loop output.
