Why your home theater sound is bad? 4 ways to improve

Why your home theater sound is bad? 4 ways to improve

1. The center speaker should always be placed above or below the screen.


Make sure the speakers are directly facing the audience.


2. The front two home theater speakers should be the same distance from the audience relative to the center line in the front of the screen.

This will ensure that the sound from the two front speakers is transmitted to our ears at the same time and in the shortest time. It is like an isosceles triangle. The distance between the two waists to the center line of the bottom is not only as long, but also the shortest. In this way, the scene and scene dubbing that occurs on the screen can be harmonious, and the sound delay is minimized. Of course, the premise is that you sit on the center line directly in front of the screen, which is also the best place to watch!

3. The rear home theater speakers should be installed on the side wall of the audience.

The purpose of the rear speakers is only to provide an atmosphere, not to provide the main sound as your home theater system. However, the positioning of the bass is more difficult than the midrange and treble of the other five speakers. The placement of bass is relatively not too fixed. You can place the subwoofer in a corner or under a table to create a surface with deeper resonance sound waves.

4. Choose the best reverberation time.

The optimal reverberation time varies depending on the use of the room. For venues such as conference venues where language is the main requirement, they must have a certain reverberation time and at the same time have a high definition, so the reverberation time cannot be too long. Usually choose about 1s. If the venue is large, the reverberation time can be extended appropriately. When the reverberation time is less than 1s, the clarity is not improved, but at the same time makes the heard sound boring. And shortening the reverberation time is achieved by increasing the sound absorption capacity of the room, which means that the sound absorption material must be increased.

For places such as Weiyuan, concert halls, etc. where music is dominant, the reverberation requirements have a great relationship with the nature of the music. Generally speaking, brisk music requires a shorter reverberation time, generally around 1s, while majestic music should have a slightly longer reverberation time, about 2s.

If the sound is transmitted through audio equipment such as a recorder, radio, etc. and then listened to, the sound heard includes the reverberation process of the sounding room and the reverberation process of the listening room, so we should choose the best reverberation in these two places time. This is the basic common sense of home theater system.

Verify the speakers are properly connected to the system. If applicable, try changing the sound mode on the system.
