Before we modify the car audio, you will often learn about some audio modification configuration packages, such as two-way, three-way packages, and subwoofer packages (the picture below shows the German Eaton CPRE S3 three-way package)... But it is correct The understanding of the role of each part of the horn in the package is still very vague, so today we will popularize the classification of car horns and the characteristics of various horns for all car owners and friends.

According to the speaker frequency classification of the speaker, it is divided into full-range speakers, tweeters, mid-range speakers, woofers and subwoofers.

1. Full-range speaker:

Full-range speakers are also called broadband speakers. Earlier, speakers that can cover the frequency range of 200-10000Hz are called full-frequency speakers. In recent years, full-range speakers have been able to cover frequencies of 50-25000Hz. The low frequency of some speakers can go down to 30Hz. Unfortunately, the current full-range speakers on the market, although they are full-range, in fact, most of their frequencies are concentrated in the mid-range range, and the expressive power of the heavy bass and treble are slightly weaker, so the sound you hear is relatively low. The flat and three-dimensional sense is not so strong.

2. Tweeter:

The tweeter is the tweeter unit in the speaker, and its function is to reproduce the high-frequency signal (the frequency range is generally 5KHz-10KHz) output from the crossover.

Because the main function of the tweeter is to express the fineness of the sound, the installation position of the tweeter is very particular. If the installation location is unscientific when refitting the car audio, the sound field effect will be unsatisfactory. The tweeter should be installed as flat as the human ear, such as on the A-pillar of the car, or above the dashboard, and some models are located on the door, so that the sound field is basically equal to the human ear, and the owner can also experience the music more. Brings the charm.

3. Mid-range speaker:

The frequency response range of the midrange speaker is between 256-2048Hz. Among them, 256-512HZ listening feels powerful; 512-1024HZ listening feels bright; 1024-2048HZ listening feels translucent.

The main performance characteristics of the midrange speaker are the realistic reproduction of the human voice, the clean and powerful tone, and the strong rhythm.

4. Woofer:

The frequency response range of the woofer is 16-256Hz. Among them, 16-64HZ listening feels deep and shocking; 64-128HZ listening feels deep, 128-256HZ listening feels full.

The main characteristic of the woofer is that it has a strong sense of shock, majestic and powerful, plump and deep.

5. Subwoofer:

Subwoofer refers to a speaker that can emit low-frequency sound of 20-200HZ. Usually, when the energy is not very strong, it is difficult for people to hear the subwoofer, and it is difficult to distinguish the sound source. In principle, the working mode of the subwoofer and the speaker are exactly the same, but the diameter of the diaphragm is larger, and the speaker for resonance is added, so the bass that people hear will feel very shocking.

It can be seen that the classification of the horn is not determined by the size of the sound emitted by the horn and its original size, but by the frequency it emits. And the speakers of each frequency band have different performance characteristics, we can choose the sound we want according to our own likes and hobbies.

So when we choose the speaker, the two-way frequency is generally the tweeter and the woofer, while the three-way frequency is the tweeter, mid-range speaker and woofer.

The above content allows us to have a cognitive concept of speakers during car audio modification and a preliminary understanding of audio modification. A complete sound system requires not only speakers that can emit each unit. The tuner is also very important. This is related to whether each unit speaker can play its own characteristics perfectly. Therefore, it is very important to choose a professional audio modification shop.
