The classification of car speaker and the characteristics of various types of speaker
According to the speaker's speaker frequency classification, it is divided into full-range speakers, tweeters, midrange speakers, subwoofers and subwoofers. 1. Full-range speakers: Full-range speakers are also called wide-band speakers. Earlier, speakers that could cover the frequency range of 200-10000Hz were called full-range. In recent years, full-range speakers have been able to cover frequencies of 50-25000Hz. Some speakers can dive down to 30Hz. But unfortunately, the full-range speakers currently on the market, although they are full-range, in fact, most of their frequencies are concentrated in the mid-band category, and the performance of subwoofers and trebles is slightly weaker. Flat and three-dimensional.

2. tweeter: tweeter is the tweeter unit in the speaker, and its role is to reproduce the high-frequency signal (frequency range is generally 5KHz-10KHz) output from the crossover. Because the main function of the tweeter is to express the delicate sound, the installation position of the tweeter is very particular. If the installation position is unscientific when the car audio is modified, the sound field effect will be unsatisfactory. The tweeter should be installed as flat as possible with the human ear, such as on the A pillar of the car, or above the instrument panel, and other models are located on the door of the car, so that the sound field is basically flat with the human ear, and the car owner can better understand the music.
3. Woofer: The frequency response range of the woofer is 16-256Hz. Among them, 16-64HZ listening feels deep and shocking; 64-128HZ listening feels full and 128- 256HZ listening feels full. The main performance characteristics of the woofer are powerful shock, strong, full and deep.
4. Subwoofer: A subwoofer is a speaker that can emit 20-200HZ low-frequency sound. Generally, when the energy of the subwoofer is not very strong, it is difficult for people to hear and it is difficult to distinguish the direction of the sound source. In principle, the working mode of the subwoofer and the speaker are exactly the same, except that the diameter of the diaphragm is larger, and a speaker for resonance is added, so the bass that people hear will feel very shocking.
It can be seen that the classification of the speaker is not determined according to the size of the sound made by the speaker and its original size, but determined by the frequency it emits. In addition, speakers in each band have different performance characteristics. We can choose the sound we want according to our preferences and hobbies. Then The two frequency divisions we saw when we selected the speakers were generally tweeters and woofers, while the three frequency divisions were tweeters, midrange speakers, and woofers. The above content allows us to have a cognitive concept of speakers when car audio conversion, and a preliminary understanding of audio modification. A complete sound system requires not only speakers capable of emitting each unit. The tuner is also very important. This is related to whether each unit speaker can play its own characteristics perfectly. Therefore, choosing a professional audio modification shop is very important.
