constant directory horn (CD)

A ConstantDirectory Horn (CD) is a horn speaker in which the sound pressure

is the same in both the vertical and horizontal directions. Generally, with traditional horn speakers, there is a sound pressure drop of about 6 dB/octave at higher frequencies. This drop starts in the frequency range between 2 kHz and 4 kHz. Equalizers can be used to compensate for this drop in level. It is different with the Constant Directory Horn, which uses a special construction with a double horn design.
