JBL Control 321CT Premium 2-Way Coaxial Ceiling Speaker (CONTROL 321CT)

The JBL Control 321CT is a premium 2-way coaxial ceiling loudspeaker designed for high-performance commercial and professional installed sound applications that require exceptional audio quality, powerful output, and distributed audio compatibility. As a member of JBL’s flagship Control Contractor Series, the Control 321CT combines advanced transducer technology, controlled coverage, and constant-voltage system integration to deliver outstanding music and speech reproduction in demanding environments.

Featuring a 12-inch Kevlar-reinforced woofer and a 1-inch compression driver, the Control 321CT delivers deep, articulate bass, highly intelligible midrange performance, and crisp high-frequency detail. The Kevlar woofer provides exceptional rigidity and durability for accurate low-frequency reproduction, while the compression driver ensures superior vocal clarity and extended high-frequency response.

With an impressive 250 watts of power handling, the Control 321CT is engineered for high-output applications where premium sound quality and reliability are essential. Its professional-grade components allow the loudspeaker to reproduce dynamic music and speech with minimal distortion, even at elevated listening levels.

The speaker incorporates an integrated 68W 70V/100V multi-tap transformer, enabling seamless integration into distributed audio systems commonly used in commercial facilities. This constant-voltage capability simplifies system design and allows multiple loudspeakers to be connected efficiently across large venues while maintaining consistent performance.

A controlled 90-degree coverage pattern provides focused and even sound distribution, helping improve intelligibility while minimizing unwanted reflections. This makes the Control 321CT particularly effective in spaces requiring precise coverage control and high acoustic performance.

The coaxial driver configuration ensures smooth integration between low- and high-frequency components, providing consistent phase response, balanced tonal character, and uniform sound quality throughout the listening area.

For enhanced low-frequency performance and structural durability, the Control 321CT utilizes a ported metal baffle design. The ported enclosure increases bass efficiency and output, while the robust metal construction minimizes vibration and contributes to long-term reliability in commercial installations.

Its architectural ceiling-mounted design allows the speaker to blend discreetly into a variety of interior environments while delivering the output and performance expected from a professional loudspeaker system.

Sold individually, the Control 321CT offers flexible deployment options for custom distributed audio installations, foreground music systems, and high-performance commercial sound reinforcement applications.

Ideal for hotels, conference centers, restaurants, retail complexes, corporate facilities, educational institutions, houses of worship, entertainment venues, hospitality environments, and professional AV installations, the JBL Control 321CT delivers premium full-range audio performance with distributed system flexibility and exceptional reliability.
