Installing auto acoustics in the door. Acoustic screen in the doorway

The front speakers are best mounted in the doors, since this is the most convenient place for installation in the cabin. Let's see how to install such a device and determine why you need an acoustic screen in the doorway and how it affects the sound.

Door Damping

The wall of the doors differs uneven surface, due to which its parts resonate in different ways. And due to this difference, the sound quality deteriorates. What is the solution to the problem? You can significantly reduce the resonance, remove the "deafness" of sound by using soft and hard materials for damping.

How to do this? Knock on the door. Where the sound is clear - put hard material, and where it is deaf - soft.

And if the resonance turns out to be too big, then the door itself will act as a conditional loudspeaker. That is, we do not get a good music scene, nor a sound quality. As we see, damping the doors has a positive effect on acoustics.

Observe the balance. If you overdo it with sound absorption, you can get a negative effect.

Acoustic screen in the door

In the area of ​​midrange and bass, the speakers in the door are directly related to the bass. If the screen of the door leaves much to be desired, no matter how steep the subwoofer is, the bass will not get its grace.

The front speakers should be so installed that they can give from 50 Hz. Otherwise you will not be able to reproduce a quality bass. So, the installation process will focus on getting a better bass sound.

There are two types of acoustic screen in the door: the inner (mounted under the lining) and the outer (the screen protrudes outward).

Internal Acoustic Screen

Advantages:

• Does not violate the appearance of the door;
• you do not need to worry about the beauty of each mechanism during the manufacture of the screen, because everything will be hidden
• Such a design will work more reliably.

Disadvantages:

• the loudspeaker will not have a beautiful design;
• the elasticity in the bass leaves much to be desired;
• changing the angle of the speaker will be very difficult.

Outdoor acoustic screen

Advantages:

• you can make a unique design for the screen
• by increasing the screen, you can make the sound cleaner;
• the ability to mount at a certain angle.

Disadvantages:

• more complex manufacturing, so you will have to spend more time and material;
• if you do not have the necessary knowledge, then it is possible to damage the speakers.

How to arrange the speakers correctly?

If we are at an angle to the loudspeaker while listening to music, then the HF is perceived worse. If the angle begins to exceed 60 degrees, then the sound quality becomes significantly worse. In this connection, the speaker should be directed to the driver at an angle of up to 60 degrees.

But not all salons can comply with this recommendation. Then try to put the value as close to the specified, because the changes in sound are significant.

The speaker produces good sound only when it is installed securely. Therefore, it is better to choose a dense material for an external acoustic screen. The usual design has a weight of 7 kg., For the highest quality you will need a screen with a mass of 15 kg.

Mandatory rule: the inner and outer shield must be connected without a single gap.

It happens that the outer screen is weakly attached to the inner screen or the latter is generally absent. No matter how qualitatively you did the outdoor screen, the presence of gaps can negate your efforts. Secure the grip of the screens securely with screws screwed in with the inclination. If there is still a small gap, then use the putty. Screws must be made of non-magnetic material, because they will be installed near the speakers.
