JBL Control 322CT - 400W 12-inch Passive 70V/100V Ceiling Loudspeaker with Pre-Attached Ported Baffle and 90-Degree Coverage in Black Finish

The JBL Professional Control 322CT is a high-performance 12-inch passive ceiling loudspeaker designed for superior sound clarity and power in professional audio environments. With its next-generation coaxial point source design, this loudspeaker offers consistent 90° coverage across a broad frequency range, making it perfect for a wide variety of commercial and industrial applications such as retail stores, conference rooms, auditoriums, and other venues that require clear speech and music reproduction. The Control 322CT features advanced technology to ensure exceptional clarity and high output, making it an excellent choice for both speech and music applications in demanding environments.

The heart of the Control 322CT is its 12-inch Kevlar-reinforced low-frequency driver, which is complemented by a medium-format compression driver for high-frequency performance. This combination delivers smooth, consistent sound with extended frequency response and minimal distortion. The low-frequency driver is designed with a 75 mm (3-inch) voice coil and utilizes a high-temperature voice coil for reliable performance in high-power situations. The result is deep, rich bass with smooth midrange frequencies, while the high-frequency driver, which features a 1.5-inch diaphragm and JBL's proprietary neodymium magnet, provides clear, extended treble for a balanced sound profile.

One of the standout features of the Control 322CT is its consistent 90° coverage pattern, which ensures that sound is evenly distributed throughout the listening area. This coaxial speaker design allows for smooth transitions between low and high frequencies and eliminates high-frequency beaming, a common issue in many loudspeakers. The speaker also delivers an impressive frequency range of 32 Hz to 20 kHz and a frequency response of 48 Hz to 19 kHz, ensuring that the audio is full-spectrum and natural-sounding. The Control 322CT provides 400W of continuous power handling (1600W peak) and can achieve a maximum SPL of 121 dB continuous (124 dB peak), making it capable of handling large spaces and delivering powerful sound even in acoustically challenging environments.

For ease of installation, the Control 322CT includes JBL's EZRail feature, which simplifies the mounting process by temporarily holding the baffle in place until it is securely attached to the backcan. This design saves installation time and ensures a secure, stable setup. Additionally, the removable multi-pin locking connector with screw-down terminals allows for quick pre-wiring of the input connections, making installation even more efficient. The optional MTC-300SG12 square grille provides a sleek, professional appearance, while the optional MTC-300BB12 backbox ensures optimal bass performance and added durability, especially in environments with challenging acoustics.

As part of the Control 322CT's transformer-equipped version, it includes a top-quality, low-saturation 100W multi-tap transformer that enables compatibility with both 70V and 100V distributed speaker lines. The transformer offers multiple tap options, including 100W, 50W, 25W, and 12.5W for 70V systems, and 100W, 50W, and 25W for 100V systems. The inclusion of the transformer allows for flexible configurations in larger systems where long cable runs are required, offering scalability and ease of use in various installations. The Control 322CT also includes a protective transformer with a 1.0 dB typical insertion loss and operates at a nominal 8Ω impedance in the Thru position, allowing multiple speakers to be used on a single amplifier channel.

Designed for durability and reliability, the Control 322CT has been engineered to withstand the rigors of professional use. Its metal baffle is constructed from high-impact polystyrene and is designed to be resistant to physical wear and environmental factors. The grille is thermoset composite-coated steel with WeatherMax multi-layer foam to protect against UV exposure, humidity, and dust, ensuring longevity and reliable performance even in harsh conditions. The speaker is also UL-listed for safety and is suitable for use in air-handling spaces when paired with the appropriate UL-listed backcan, such as the MTC-300BB12. The Control 322CT passes JBL's rigorous 100-hour torture power test to ensure long-term performance in demanding environments.
