What Is Constant Directivity Horn?

- Jun 22, 2018-

The constant directivity horn was invented by the United States EV Corporation. The acoustic wave front in the horizontal and vertical planes of the throat is designed to be circular and orphan-shaped and propagates inside the horn, so it remains unchanged at the opening. The radiation in the directivity state enables the horizontal directivity and vertical directivity to remain substantially constant when the frequency changes, solving the problem that the treble gradually decreases when the listener deviates from the axis of the signature axis, the dispersion characteristics are better and the sound propagation is good.
