The JBL CONTROL 328C is a premium, high-output coaxial ceiling loudspeaker engineered for superior distributed audio performance in demanding commercial and architectural installations. This model features a true coaxial design, integrating an 8-inch low-frequency driver with a 1-inch titanium compression driver mounted concentrically at its center. This alignment ensures perfect acoustic coherence, resulting in a uniform wavefront, exceptional phase accuracy, and consistent off-axis frequency response. Designed for integration with a separate back can or in plenum-rated spaces, it is an ideal choice for high-fidelity applications in corporate boardrooms, performing arts center lobbies, high-end retail environments, and worship facilities where both sonic excellence and visual discretion are required.

The speaker's performance is characterized by its extended frequency response, high power handling, and outstanding clarity. The 1-inch titanium compression driver is coupled to a sophisticated constant-directivity waveguide that provides controlled dispersion, minimizing ceiling reflections and ensuring even tonal balance throughout the coverage area. This design is critical for achieving both detailed music reproduction and superior speech intelligibility. The CONTROL 328C is compatible with standard 70V/100V distributed audio systems via its integrated multi-tap transformer, while also supporting low-impedance operation for applications demanding the highest audio fidelity. This flexibility allows installers to easily balance output levels across different zones within a complex audio system.

Built for professional installation and long-term reliability, the speaker features a rigid die-cast aluminum frame and a paintable, low-profile grille that sits flush with the ceiling tile for a clean, unobtrusive appearance. Its robust construction ensures stable performance in a variety of environmental conditions. By combining true coaxial driver technology, a controlled dispersion waveguide, and versatile system compatibility, the JBL CONTROL 328C provides integrators with a top-tier ceiling speaker solution capable of delivering powerful, articulate, and evenly distributed full-range sound in high-end commercial audio environments.
