I guess he dosn't know either
Conical (T -> infinite)
The conical horn is the simplest horn shape. The cross-section increases linearly. The variation of the radiation impedance is similar to that of the diaphragm.
Compared with exponential horns, conical horns have a precisely defined radiation characteristic. They belong to a group for which the one-dimensional wave equation can precisely describe the states in the horn.
It is frequently used as the shape for so-called 'constant directivity' horns, which manifest a homogeneous radiation characteristic over a wide frequency range.
Another advantage is that the cross-sectional area in the vicinity of the horn throat increases more rapidly than for exponential horns. This thus reduces the sound pressure in the horn as well as distortions due to the compressibility of air.
The only disadvantage of the horn shape is its size.
