The JBL CONTROL 45C/T is a high-fidelity coaxial ceiling loudspeaker designed for premium distributed audio applications in commercial and residential settings. This two-way system features a 5.25-inch mineral-filled polypropylene woofer integrated with a coaxially mounted 0.75-inch soft-dome tweeter, creating a coherent point-source sound field with wide, even dispersion. The inclusion of a multi-tap transformer makes it specifically engineered for integration into 70V or 100V constant-voltage audio systems, which are standard in background music, paging, and multi-zone installations for offices, retail stores, restaurants, and hospitality venues. Its design prioritizes both sonic accuracy and aesthetic discretion, delivering clear, detailed audio while maintaining a low visual profile.

The coaxial driver configuration ensures precise acoustic alignment between the low and high-frequency components, resulting in uniform frequency response across a broad listening area and excellent off-axis performance. This translates to consistent tonal quality and superior speech intelligibility, which is critical for both music reproduction and voice announcements. The built-in transformer offers multiple power tap settings, allowing installers to precisely match the speaker's output level to the acoustic requirements and size of the zone, optimizing system headroom and efficiency. The speaker's crossover is optimized for smooth integration between the drivers, providing a seamless listening experience.

Installation is streamlined for contractor-friendly deployment in standard suspended ceiling grids. The speaker utilizes a conventional mounting system with a low-profile, paintable steel grille that can be finished to blend with the ceiling. The transformer is pre-wired to an accessible terminal cup, simplifying the connection process. Built to JBL's professional standards for durability and performance, the CONTROL 45C/T offers a combination of superior coaxial acoustics and the convenience of integrated voltage transformation, providing a reliable, high-quality audio solution for integrators designing clear and reliable sound systems for commercial spaces.
