Description

The Cobreflex IIB is a highly efficient, exponentially flared reflex horn, expertly designed for public address, paging, and voice warning systems in the audio industry. Its innovative reflex construction ensures both compactness and enhanced performance when paired with the right compression drivers. Featuring a patented (patent # 2,751,996) folded design, it integrates two separate air columns within a single assembly, effectively preventing high-frequency phase cancellation common in re-entrant horn systems.

With an 80-degree horizontal and 60-degree vertical dispersion pattern, the Cobreflex IIB offers optimal wide coverage for various audio applications. It delivers exceptional acoustic loading down to a low-frequency cutoff of 250 Hz, making it versatile for diverse sound environments.

Constructed from robust acrylonitrile butadiene styrene (ABS) with an ultraviolet-resistant grey paint finish, the Cobreflex IIB is built for durability. It includes a serrated positive-lock “U” mounting bracket, ensuring maximum mounting flexibility and ease of installation for audio professionals.
