JBL Professional Control 14C/T-BK - 4" Coaxial Ceiling Speaker with Integrated Backcan and 70/100V Transformer (Black, 2-Pack)
The JBL Professional Control 14C/T-BK is a compact and reliable two-way ceiling loudspeaker designed for commercial installations that demand high intelligibility and wide, uniform coverage. Its coaxial architecture combines a 100mm woofer with a polypropylene cone and butyl rubber surround with a 19mm liquid-cooled soft dome tweeter, mounted in a vented, paintable baffle made of UV-resistant ABS (UL94-V0 and UL94-5VB ratings). The blind-mount metal backcan comes pre-installed, streamlining a clean installation from the ceiling face and ensuring stable performance in air handling spaces.
With a bandwidth of 74 Hz to 20 kHz (−10 dB), 120° conical coverage, and 87 dB sensitivity, the Control 14C/T-BK delivers consistent sound for voice and background music in retail, hospitality, education, offices, and public spaces. It offers flexible operation: it can work with low impedance (8 Ω) or on 70/100 V lines using a multi-tap transformer. It includes professional hardware (C-ring and tile rails), a cutting template, a paint mask, and a grille, facilitating a professional result with minimal installation time. Finished in black (-BK) and supplied in pairs (2 units).
