12” High Power Coaxial Open-Ceiling Speaker

Patented BroadBeamHP® waveguide technology providing smooth response and maximum SPL across the audio spectrum. One 12 inch (305 mm) treated fiber cone with a treated cloth surround and one 1.375 inch (35 mm) Mylar compression driver with waveguide. Ported enclosure for added bass response (down to 73 Hz, – 10 dB). High-SPL, high-efficiency system for the sound reinforcement and PA markets. Easy-access, five-position tap switch for 25/70.7/100-volt applications with transformer bypass position. Reduced amplification costs and maximum efficiency (97 dB sensitivity), with 8-ohm impedance. UL 1480 (UEAY) and 2239 (hanging cable) approved. Included accessories: hanging hardware, Euroblock connector, terminal weather boot.
