Before we talk about whether it is necessary to install a center speaker in a car stereo, let's briefly understand the role of the center speaker.
The center speaker can be understood as a mid tone or a mid high tone. It is an independent channel, not a speaker unit. That is to say, it is a loudspeaker located between the left and right channels.
The so-called center speaker is generally located in the middle of the left and right channels. It should be noted that it is not a random purchase of speakers, and then placed in the middle is the center speaker. The central horn is mainly used to change the sound field and balance the sound.
That's the problem. I believe many car users will think that if we buy a mid speaker and add it to our car's audio system, it will sound better? The answer is no.
The center speaker is provided with an independent center audio signal by the power amplifier. This middle signal is generated by mixing left and right audio channels. The significance of this is that the center unit can form a stereo system with both left and right channels, so as to provide stereo effects for both positive and negative driving positions.
Conventional models do not have a separate mid channel output, so you can only select and place it on the left or right speaker line. No matter which option you choose, you can't achieve the effect pursued by independent mid track. In addition, the crossover point, crossover slope and delay data of the middle channel will obviously affect the hearing. Therefore, buying a mid speaker and putting it on a certain speaker line can not be regarded as the real mid speaker.
Because the distance between each speaker on the car and the listening position is different, the sound from the left and right channels cannot reach the ear at the same time. The greater the time difference, the more serious the impact on the sense of hearing. The multi-channel sound system can let all passengers enjoy high-quality stereo effect as much as possible through the layout of the speaker installation position.
This is exactly what the stereo system lacks, so if your car itself is a stereo system. If you want to get a more balanced sound, instead of feeling that the left ear hears music first, and the right ear hears it again, you can add a center speaker, which can adjust the sound field of the front passenger and passenger seats, and also adjust the hearing of the rear passengers, so that the overall music performance is more balanced.
The vast majority of models are designed with two frequency division. The middle unit can be either a mid tone unit or a mid high tone unit, which has significantly improved the performance of the mid frequency. However, the precondition for adding is to add a DSP with central output. And the tuning technology must be good. Each tuning parameter in the center has a significant impact on the sound effect. If there is a problem with debugging, you may feel that the effect is not as good as before.
Again, I remind you that car audio equipment can only determine the upper limit of the audio system. The lower limit is really determined by the scheme collocation, installation and commissioning. If the lower limit is not determined properly, even the priceless equipment will not help.
