1. Car audio three-way installation method
There are three installation methods for car audio three-way: passive three-way, fully active three-way and semi-active three-way frequency division.
1. Passive three-way frequency
Advantages: simple installation and debugging, saving power amplifier, only one or two power amplifiers can push the three-way frequency of six speakers.
Disadvantage: The delay and other parameters of the three loudspeaker units cannot be adjusted individually, but can only be adjusted together. The sound field positioning is not precise enough.
2, full active 3-way frequency
The 6 speakers with 3-way frequency are pushed by 6 channels respectively. Advantages: Delay and other functions can be adjusted separately, and the sound field positioning is more accurate; get rid of the frequency divider, the control of the mid-low frequency is better, and the speed is faster. Disadvantage: waste of power amplifier. Several amplifiers are required.
3, semi-active three-way frequency
6 speakers are pushed by 4-way power amplifier. Most of the modified three-way treble and midrange are inverted on the A-pillar, their delay data is the same, and the power is also small, so they can share a power amplifier to promote. Advantages: save power amplifier, debugging is relatively simple.
Two or six kinds of car audio three-way speaker installation positions
Three-way speaker system in high-end cars In the audio system, such as DLS, RS, and Hz, as well as the world’s top French FOCAL’s Utopia Be series No7 set. The three-way speaker system can overcome the phenomenon that the distance between the two-way treble and the mid-bass is too far, which causes the sound image of the mid-frequency part to be blurred and the positioning is uncertain. Therefore, most of the top systems in high-end car audio brands have three-way speakers. suit.
The three-way speakers are placed in the following ways:
1. The treble, mid-range and bass are installed on the pedals
This This installation phenomenon is similar to the first installation method of two-way speakers. It can be said that it has the widest sound field effect and the best positioning and imaging force installation method if it is properly debugged.
2. The treble, midrange are installed on the foot pedal, and the bass is installed under the door panel
This installation method and the first installation method can be complementary, and the bass is installed on the door panel The distance will not affect the connection problem of the mid-low frequency.
3. The treble and midrange are installed on the instrument panel, and the bass is installed under the door panel
This method is more commonly used in domestic modification. For example, the same type of modification of two-way frequency, when designing the system, it is best to have multiple EQs to control the overall sound performance.
4. The treble and midrange are installed on the A-pillar, and the bass is installed under the door panel.
This method is also used by many people in China. It has a great impact on the height of the sound field and the sound Compared with the two-way frequency, the overall performance of the mid-frequency is better in density, thickness and sound realism.
5. The treble, mid-range and bass are installed on the door panel
6. The tweeter is installed on the A-pillar, and the mid-range and bass are installed under the door panel
This installation method is a more common design method, and it is also accepted by many fever and recommended by the store. The high-pitched A-pillar is installed to improve the height and width of the sound field, making the entire sound field listen to the best effect. The midrange and mid-bass are equipped with door panels, and the door panels are used as the cabinet to produce the fullest sound.
The above two methods can be said to be some changes of the two-way set. You can refer to the article “5 kinds of car audio two-way speaker installation positions”, which will not be described in detail here.
