Description
The JBL Control 321C 12" 2-Way 250W Coaxial Ceiling Speaker 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.
Key Features:
- Coaxial ceiling speaker with pre-attached ported baffle
- For use with low-impedance power amplifiers
- Long-term power handling of 250W (1000W peak)
- Durable 12" Kevlar-reinforced cone serves as a waveguide for high frequencies
- Metal throat transitions smoothly to the horn to eliminate high-frequency beaming
- High-temperature voice coil
- High-frequency driver features a pure titanium diaphragm for high sensitivity and long life, a diamond surround for resonance control, and FerroFluid for increased power handling
- Consistent 90° coverage on a broadband basis
- Built-in crossover network with 18 dB/octave high-pass filter and 12 dB/octave low-pass filter
- Integrated EZRail temporarily holds one side of the speaker baffle in place until the installer can affix the baffle to the backcan with screws
- Removable multi-pin locking connector with secure screw-down terminals allows pre-wiring of inputs for easy clip-on convenience during installation
- Compatible with MTC-300SG12 grille, and MTC-300BB12 backbox (both available separately)
