12” High Power Coaxial Open-Ceiling Speaker

Patented BroadBeamHP® waveguide technology delivers a consistent dispersion pattern for maximum coverage area per speaker. One 12 inch treated fiber cone with a cloth surround concentrically mounted to a 1.375 inch mylar compression driver with waveguide. High-SPL, high-efficiency system for the sound reinforcement and PA markets. An impressive 2 cubic foot, ported ZeroReflection™ enclosure for added bass response, rigidity and optimal sound reproduction. Easy-access five-position tap switch with 25-, 70.7-, 100-volt and transformer bypass position. High efficiency for reduced amplification costs and max output for distributed or 8 ohm systems. Low insertion loss 150-watt transformer. UL 1480 (UEAY) and 2239 (hanging hardware) approved. Included accessories: impact-resistant steel grille, hanging hardware, Euroblock connector, terminal weather boot.
