JBL Professional Control 12C/T - 3" Compact Ceiling Speaker with Integrated Backcan and 70/100V Transformer (Black, 2-Pack)
The JBL Professional Control 12C/T is a compact, full-range ceiling loudspeaker designed for high intelligibility and wide coverage in commercial installations. It features a 76 mm (3") driver mounted in a vented, paintable baffle (UV-resistant ABS, UL94-V0 and UL94-5VB rated) with a pre-installed, blind-mount metal backcan . Its 130° cone pattern and 68 Hz to 17 kHz (−10 dB) bandwidth ensure consistent on- and off-axis sound, ideal for background music and announcements in retail, hospitality, offices, and public spaces. The depth behind the baffle is only 138 mm, making it easy to install in shallow suspended ceilings. It operates at low impedance (8 Ω) and on 70/100 V lines via a multi-tap transformer, and is supplied in a black (-BK) finish in a 2-pack.
