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

The JBL Professional Control 14C/T is a versatile, high-performance ceiling speaker designed for a wide range of applications, providing clear, high-quality sound with minimal visual impact. Its 120° coverage pattern and sleek design make it ideal for environments such as business music systems, airports, retail stores, restaurants, hotels, educational facilities, conference rooms, lounges, and more. This speaker offers outstanding performance for both foreground music and paging systems, delivering consistent audio coverage and reliable performance over extended periods of use.

The Control 14C/T features a 100 mm (4-inch) full-range low-frequency driver with a polypropylene cone and butyl rubber surround, ensuring deep bass response down to 74 Hz. The driver's design, which includes an anodized aluminum voice coil former and a high-temperature voice coil, guarantees stable performance even under long-term, high-power usage. Additionally, the high-technology FEA-optimized motor construction and linear suspension spider design contribute to smooth frequency response and consistent off-axis performance, making it suitable for wide coverage areas.

The 19 mm (0.75-inch) high-frequency driver uses a highly damped, treated silk dome for a clear and warm sound profile. It is coupled with a Kapton voice coil and liquid cooling to ensure excellent high-frequency extension and power handling. The wide dispersion waveguide incorporated into the design provides uniform coverage, delivering a smooth frequency response that reduces distortion and ensures clarity throughout the listening area. The speaker's removable locking connector with screw-down terminals ensures a secure and stable connection, with "loop-through" terminals for easy daisy-chaining, while dual strain relief assemblies are included to clamp cables or flex conduits securely.

Designed for both low-impedance (8Ω) and distributed 70V/100V systems, the Control 14C/T is equipped with a multi-tap transformer that provides flexible installation options. It can be used as a 30W, 15W, or 7.5W transformer tap at 70V/100V, and the 8-ohm setting supports 30W nominal power handling. The speaker's frequency response spans from 74 Hz to 20 kHz with a continuous power handling capacity of 60W (120W peak), making it a robust solution for various audio needs. With a sensitivity of 87 dB and a rated maximum SPL of 108 dB peak at 1 meter, this speaker ensures high output and clarity across a wide area.

For ease of installation, the Control 14C/T features a pre-attached backcan for quick setup and integration into ceiling spaces. The backcan depth is 181 mm (7.1 inches), with a ceiling cutout diameter of 170 mm (6.7 inches), making it suitable for shallow ceiling areas. The baffle is made from UV-resistant ABS material with a UL94-V0 and UL94-5VB fire rating, ensuring durability and safety. Additionally, a paint shield and grille are included, and the speaker's baffle can be painted to match the surrounding decor. The Control 14C/T comes with a C-ring support backing plate, two tile rail supports, and safety seismic attachment points for secure installation. Optional accessories such as the MTC-24NC new construction bracket and MTC-TCD thick-ceiling dogears are also available to accommodate various installation scenarios.
