Description
The JBL Control 322CT is a passive 12″ coaxial ceiling speaker with a multi-tap transformer designed for voice amplification and foreground music reproduction in waiting rooms, offices, retail stores, and restaurants. With a low-saturation transformer for compatibility with a 70V/100V power amplifier (available separately), this 2-way speaker provides a long-term power capacity of 400W (1600W peak). The Control 322CT is equipped with a durable 12″ Kevlar-reinforced cone and a medium-format compression driver, yielding an extended frequency response of 48 Hz to 19 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 easy wiring at the desired power tap setting.
Coaxial ceiling speaker with pre-attached ported baffle
Low-saturation 68W multi-tap transformer enables use with 70V/100V constant-voltage systems
Long-term power handling of 400W (1600W 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 3″ voice coil
Medium-format compression driver features a radial slot phase plug for a smooth, extended high-frequency response, along with a neodymium magnet for low installation weight
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)
