Room acoustics is especially important. This is a huge subject, which is closely related to the geometry of the room, the reverberation time, the reflection and refraction of the sound, the material properties of the interface, and so on. Again, we only give a few relatively important suggestions, I hope to help everyone:
1. First, choose or build a room without parallel walls.
2. Ensure that the reverberation time is shorter and more balanced in each frequency band.
3. The early reflection sound must be processed, and its sound pressure is at least 20 dB lower than the direct sound.
4. Under normal circumstances, if diffuser/diffusion materials are used, they should be located behind the room.
5. If the speaker is embedded, the front wall must be a hard wall, and the front surface of the speaker should be flush with the wall.
6. If you only use a free-standing speaker (such as a floor stand), you can use sound absorbing materials on the front wall.
After the room has been acoustically treated, pay attention to the following:
1. Set the angle of the speaker according to the international standards of the audio industry.
2. Try to place the speaker in a proper position so that the reflected sound from the side wall and the back wall does not produce low-frequency offset, ensuring a correct and good low frequency.
3. Make sure that the sound axis of the speaker is aligned with the listening position in the horizontal and vertical directions.
4. According to the instructions in the manual and quick setup guide, reasonably adjust the room response control on the speaker to make the speaker have a more flat frequency response in the room.
