Horns are usually different from speakers of other structures. In many cases, this difference is mainly reflected in the sound field.
However, different types of horns with different designs have different sense of hearing. For example, horns with different DI values will affect the IACC, so the ASW sound image width is different.

Zhuanlan.zhihu.com Of course, the sense of hearing of the horn with constant and non-constant directivity is also different. One view is that speakers with constant directivity or slowly changing sound quality are better, but this has a prerequisite that is based on a stereo recording and playback system. If it is for the center channel of a multi-channel system, whether it is a home theater or a car audio, the directivity of the center speaker is not necessarily constant. For a home theater system where the center channel plays most of the human voice dialogue, if the center speaker is a horn, adjust the size and shape of the horn section in different segments to make the directivity closer to the directivity of human voice, but the sound image may stand up More realistic. However, if you use monitor speakers with constant directivity when recording, you must also consider the sound staining caused by the off-axis frequency response of the non-continuous directivity design horn in the actual debugging. Then the frequency response curve is used in acoustic or EQ debugging. The optimal solution is not necessarily straight.
