JBL Control 14C/T-BK - 60W 4-inch Passive 2-Way 70V/100V Ceiling Loudspeaker with Backcan and 120-Degree Coverage in Black Finish

The JBL Professional Control 14C/T-BK is a versatile, high-performance ceiling loudspeaker that delivers exceptional sound quality in low to medium volume environments. Its sleek black finish and compact design make it an ideal solution for applications such as business music systems, retail stores, music/paging systems, airports, lounges, conference rooms, hotels, and educational facilities. With a wide 120° conical coverage and a high-quality design, the Control 14C/T-BK ensures clear, consistent sound both on and off-axis, making it suitable for a wide variety of commercial spaces that require unobtrusive yet powerful audio.

Equipped with a 100 mm (4-inch) full-range low-frequency driver, the Control 14C/T-BK offers exceptional bass response down to 74 Hz. The polypropylene cone and butyl rubber surround ensure durability and excellent sonic damping, while the anodized aluminum voice coil former and high-temperature voice coil ensure reliable performance in high-power, long-term conditions. The FEA-optimized motor construction, along with the linear suspension spider design, results in smooth frequency response and consistent off-axis performance, perfect for larger rooms or spaces where even sound distribution is necessary.

The high-frequency driver of the Control 14C/T-BK is a 19 mm (3/4-inch) soft-dome tweeter that is liquid-cooled for improved power handling and extended performance. The treated silk dome ensures clear and warm high-frequency sound, while the Kapton voice coil and wide-dispersion waveguide provide smooth and wide coverage. This tweeter design contributes to the speaker's consistent frequency response and minimizes distortion, even at higher volumes, ensuring that every listener receives the same audio quality regardless of their location in the room.

Designed for flexibility, the Control 14C/T-BK can be used in both low-impedance (8 ohms) and distributed systems (70V/100V), making it suitable for a range of applications. The multi-tap transformer offers 25W, 12.5W, and 6.3W taps for use with 70V or 100V systems, while the direct 8-ohm operation option ensures ease of integration with other speakers in a low-impedance system. The speaker has a continuous power handling of 60W, with a peak rating of 120W, and a maximum SPL of 108 dB at 1 meter, making it powerful enough for medium to large spaces while maintaining sound clarity.

For ease of installation, the Control 14C/T-BK features a pre-attached backcan that facilitates quick and secure mounting in ceiling spaces. The blind-mount system ensures hassle-free installation, with a ceiling cutout size of 170 mm (6.7 inches) and a compact backcan depth of 181 mm (7.1 inches), which is suitable for shallow ceiling cavities. The speaker is equipped with dual strain reliefs, clamping mechanisms for cables or flex conduits, and a removable locking connector for secure wiring. Additionally, the speaker includes a C-ring support backing plate and tile support rails for versatile mounting in various ceiling structures.

The Control 14C/T-BK is UL listed and compliant with various safety standards, making it a reliable and durable choice for commercial installations. The speaker's robust design includes UV-resistant materials and fire-rated components to ensure long-lasting performance in demanding environments. It also features a seismic attachment ring on the top surface for added safety during installation.
