Car horns are divided into: frequency division unit (horn), coaxial unit (coaxial horn) and subwoofer (subwoofer). Suit speakers are mainly divided into "dual-frequency speakers" and "triple-frequency speakers". Dual-band speakers are composed of bass speakers and independent tweeters, and tri-band speakers are composed of three different speakers: high, medium and low.
Because of the clear distinction between different ranges, the crossover speaker can form a good sound field effect and layering, which is the first choice for many car audio enthusiasts. Coaxial unit because all range units are assembled on one speaker, it is not satisfactory in terms of sound phase positioning and timbre, so it is not recommended to start with this kind of products. However, this kind of speaker is relatively cheap and is generally purchased by junior audio enthusiasts. Subwoofer bass performance is very good, can form a very shocking music effect. It is a car horn that friends who like DJ and dance music can't miss.
