In 1975 don keele presented a paper at the 51st convention of the audio engineering society that introduced the modern constant directivity horn. This is the reason corrective eq is used to flatten the response. At any point throughout the horn’s coverage angle, the quality and decibel level of a sound emitted remains constant within 6db.

A new horns family is presented, the hybrid constant directivity (hcd), investigating some practical aspects of constant directivity design through physical and fea 3d prototypes. The tweeter is generally a compression driver, but does not have to be. This horn has an even 120° horizontal and 60° vertical coverage angle for all speech reproductions. Using a novel equation that correlates the matrix of a virtual horn and measured compression driver pressure, it is possible to easily predict the absolute sound pressure level (spl) of the.
