Electro-Voice COBREFLEX IIB Folded Sectoral Horn

Optimize your facility's mass notification and public address performance with the Electro-Voice COBREFLEX IIB folded sectoral horn. As a high-efficiency horn from Electro-Voice, the Cobreflex IIB is engineered to deliver clear, intelligible voice messaging across large indoor and outdoor spaces—critical for security, surveillance, and emergency monitoring systems. Its patented folded reflex geometry minimizes high-frequency phase cancellation, while the 80° horizontal by 60° vertical dispersion pattern provides wide, even coverage that reduces speaker count and installation complexity. The horn maintains strong low-frequency loading down to 250 Hz, ensuring voice presence and improved speech intelligibility when paired with suitable compression drivers. Built from UV-inhibited, weather-resistant ABS and supplied with a serrated positive-lock 'U' mounting bracket, the Cobreflex IIB is compact, durable, and quick to deploy in PA, paging, and mass-notification networks. Ideal for campuses, transit hubs, industrial sites, and integrated security installations, this horn enhances monitoring and response capabilities. Integrate the Electro-Voice Cobreflex IIB into your next mass notification or security audio project—contact sales or add to cart to specify mounting and driver compatibility.
