JBL Control 14C/T 4" Full-Range Ceiling Speakers 100V/8 Ohm (Pair)
The JBL Control 14C/T is a 4" 2-Way Full-Range Ceiling Speaker delivering wide 120° conical coverage across 100V line and 8 Ohm operation, combining a high-output cone driver with a liquid-cooled soft-dome tweeter for excellent sound quality across a wide range of commercial applications.
The JBL Control 14C/T has been designed to provide excellent sound quality across a wide variety of medium volume applications — including music cafes, retail stores, business music systems, airports, reception and waiting rooms, lounges, courtrooms, convention centres, hotels, educational facilities and more. Its wide 120° conical coverage ensures consistent, even sound quality for listeners both on and off axis, making it an ideal choice wherever broad, uniform audio distribution is required from a single ceiling speaker. The addition of a dedicated 19mm liquid-cooled soft-dome tweeter over the Control 12C/T gives the 14C/T a notably extended and more detailed high-frequency performance, with a frequency range reaching all the way to 20kHz.
High-Technology 2-Way Driver Design
The Control 14C/T features a carefully engineered 2-way driver system comprising a 100mm (4") high-output low-frequency driver and a 19mm (¾") soft-dome high-frequency tweeter, crossed over at 2nd order (12dB/octave). The 4" LF driver features a lightweight, high-temperature anodised aluminium voice coil former, high-temperature grade voice coil and FEA-optimised motor construction for stable, reliable performance under long-term and high-power operating conditions. A linear suspension spider design ensures a smooth frequency response and consistent off-axis performance, whilst the butyl rubber surround provides long-term durability and excellent sonic damping. The polypropylene cone is water and humidity resistant for reliable performance across a wide range of installation environments.
The 19mm HF driver features a highly damped and treated silk dome for clear, warm high-frequency reproduction, a lightweight Kapton™ voice coil for improved HF response and reliability, low-viscosity liquid cooling for enhanced power handling, and a wide-dispersion waveguide design for broad, smooth high-frequency coverage across the listening area.
Dual Operating Modes for Maximum Flexibility
The Control 14C/T is switchable between 8 Ohm low-impedance direct operation and 70V or 100V distributed audio systems, accommodating a 25W multi-tap transformer with taps at 25W, 12.5W and 6.3W at both 70V and 100V — plus an additional 3.2W tap at 70V. This dual-mode flexibility makes it straightforward to integrate the Control 14C/T into virtually any new or existing audio system, from simple direct-drive setups to large-scale distributed PA installations.
Quick & Easy Installation
The Control 14C/T has been designed with fast, hassle-free installation firmly in mind. A pre-attached blind-mount backcan eliminates the need for separate backcan assembly, whilst a removable locking 4-pin connector with screw-down terminals accommodates wire up to 12 AWG and provides loop-through connectivity for easy daisy-chaining. Dual strain relief assemblies provide secure clamping for use with either cable or flex conduit. Two tile rail supports, a C-ring support backing plate and a cutout template are all included in the box to further simplify the installation process. A safety seismic attachment ring on the top surface provides an additional security fixing point where required.
Safety Compliant & Plenum Rated
The Control 14C/T carries an impressive range of safety approvals and compliance certifications, including UL1480, UL2043, NFPA90, NFPA70 and CE. The ABS baffle meets UL94-V0 and UL94-5VB flammability ratings, and the integrated backcan is suitable for use in air handling (plenum) spaces — making it compliant for installation in the widest possible range of commercial ceiling environments. The baffle is paintable and UV resistant for a discreet, long-lasting finish. Available in White or Black. Sold as a pair.
