JBL Professional Control 18C/T - 8" Coaxial Ceiling Speaker with Integrated Backcan and 70/100V Transformer (Black, 2-Pack)
The JBL Professional Control 18C/T is a two-way ceiling loudspeaker designed for high intelligibility and balanced musical response in professional installations. It features a 200mm woofer with a polypropylene cone and butyl surround, along with a 25mm liquid-cooled soft dome tweeter. Its paintable baffle (UL94-rated ABS material) and integrated, blind-mount metal backcan simplify installation in suspended ceilings and plenum spaces, ensuring stable long-term performance. Thanks to the built-in multi-outlet transformer, the Control 18C/T can operate on 70/100V lines or at low impedance (8Ω bypass), meeting the needs of background music, speech, and announcements with a controlled 90° conical coverage. This model is available in black (-BK) and in a pack of two.
