At present, the car horn set on the market is mainly divided into two frequency and three frequency, of which two frequency is more, belonging to the entry level set. The two-tone speaker kit includes a pair of tweeters, a pair of woofers, and a pair of dividers. The function of the frequency divider is to separate the high frequency band from the middle frequency band at the preset frequency point in the factory. Compared to the two - division, the three - division set speaker has a pair of alto speakers.

Coaxial speakers as the name suggests, high and medium share a shaft, some high-end coaxial speakers also use capacitive frequency division.

The advantage of suit horn: high pitch and middle tone separation, high pitch head can be promoted to make the sound field position increase to the ear side of the listener, sound sounds layered feeling is very strong, more suitable for the front door (front) and back door (rear).

The disadvantage of suit horn: the price is about one times higher than coaxial horn; Construction is more complex and has higher requirements for construction personnel.

Coaxial speaker advantages: the price is cheaper; Construction is easy.

Disadvantages of coaxial horn: high pitch and alto can not be separated, resulting in speakers such as in the original car horn often makes the sound field deviation, leading to the listener is difficult to feel the existence of high pitch, sound no sense of hierarchy and permeability, more suitable for the rear of the car.
