The JBL's CONTROL 12C/T is a pair of 40W passive ceiling loudspeakers that designed to give generous coverage and attractive sound for low- to medium-volume applications. This public address system with a three-dimensional design is a full-range driver capable of handling up to 40W of continuous programme power, with a peak maximum SPL of 103 dB and a frequency range of 68 Hz to 17 kHz (-10 dB), and a 130° conical dispersion pattern that ensures more coverage with fewer speakers. The integrated 15W multi-tap transformer has taps at 70V and 100V, as well as a transformer bypass mode for 8 ohm low-impedance operation. The UV-resistant, paintable ABS baffle has a pre-attached rear can that makes installation quick and easy.
