Description
The JBL Control 328C 8" 2-Way 250W Coaxial Ceiling Speaker is a passive 8" coaxial ceiling speaker designed for voice amplification and foreground music reproduction in waiting rooms, offices, retail stores, and restaurants. When driven by an 8-Ohm power amplifier (available separately), this 2-way speaker provides a long-term power capacity of 250W (1000W peak). The Control 328C is equipped with a durable 8" Kevlar-reinforced cone and a titanium-diaphragm compression driver, yielding an extended frequency response of 60 Hz to 16 kHz.
The cone and pre-attached baffle serve as a high-frequency waveguide, which results in reliable 120° 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 8-Ohm power amplifiers
- Long-term power handling of 250W (1000W peak)
- Durable 8" Kevlar-reinforced cone with 2" voice coil
- Low-frequency cone and shaped mounting baffle perform as a true 12" diameter waveguide for the 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 120° coverage on a broadband basis
- Built-in crossover network with 18 dB/octave high-pass filter and 12 dB/octave low-pass filter
- 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-RG6/8 and MTC-SG6/8 grilles, and MTC-300BB8 backbox (all available separately)
