The Electro-Voice EVID-C4.2LP is a low-profile (3.7") 4-inch coaxial two-way ceiling loudspeaker system. Featuring a waveguide-coupled titanium-coated dome tweeter and 4-inch woofer, it delivers a frequency response of 60 Hz - 20 kHz with 86 dB sensitivity. The system includes full bandwidth overload protection and a 2nd order crossover network at 2.5 kHz. It features transformer taps for 70V/100V systems (1.88/3.75/7.5/15W) or 8 ohm bypass, selectable via front baffle switch. Designed for wide dispersion with a 130° conical coverage pattern, the speaker has a rated impedance of 8 Ω and 50 W power handling. Its steel enclosure with UL94V-0 rated baffle and white powder-coated grille makes it suitable for permanent ceiling installations in commercial environments.
