JBL Professional Control 14C/T - 4" Coaxial Ceiling Speaker with Integrated Backcan and 70/100V Transformer (White, 2-Pack)
The JBL Professional Control 14C/T is a two-way, full-range ceiling loudspeaker that combines a 100mm woofer with a polypropylene cone and butyl rubber surround with a 19mm liquid-cooled soft dome tweeter. The unit is housed in a vented, paintable, UV-resistant baffle (UL94-V0 and UL94-5VB rated ABS) with a pre-installed, blind-mount metal backcan , simplifying installation in suspended ceilings and ensuring stable performance over time. Its 120° conical coverage and 74Hz to 20kHz frequency response (−10dB) deliver consistent sound for speech and background music in retail, hospitality, education, and corporate environments. It operates at both low impedance (8 Ω) and 70/100V line power via a multi-tap transformer.
Main features
- 2-way coaxial design: 100mm woofer (polypropylene, butyl surround) + 19mm liquid-cooled soft dome tweeter with wide dispersion waveguide.
- Uniform 120° coverage and consistent off-axis ringing to reduce "hot spots" and coverage gaps.
- Frequency response (−10 dB): 74 Hz–20 kHz; (±3 dB): 100 Hz–20 kHz.
- Nominal sensitivity: 87 dB; Max. SPL at 1 m: 102 dB average / 108 dB peak at low impedance.
- Flexible operation: low Z 8 Ω (30 W continuous pink noise / 60 W program) and 70/100 V transformer with 25/12.5/6.3 W taps (and 3.2 W only at 70 V).
- Professional installation: removable 4-pin connector with screw terminals and loop-through passage (up to 2.5 mm²), double cable gland for cable or flexible tube and seismic anchor point.
- Robust construction: paintable UL94-V0/5VB ABS baffle and zinc-plated steel backcan ; suitable for air handling spaces.
