First, the inner side of the axis pendulum method: first put the speaker between one-third to one-half of the length of the room, and then the speaker as far as possible to the side wall, if the room is too wide, then it does not have to be close to the side wall . The inward angle of the speaker should be greater than 45 degrees, and the listening position should be between 0.5 and 1 meter after the intersection of the projection angles of the two speakers.
Effect: If your hearing environment is complicated, the sound absorption is asymmetrical, the room is three-pointed and the octagonal, the room is too slender, and the sound of your speaker is sharp, the midrange is thin, the bass is not enough, the following "axial side method" "I believe it will help you."
Second, the equilateral triangle method: the first condition is that the speaker should leave the back wall (at least 1 meter or more) and the side wall (at least 0.5 meters or more). The second condition is to draw the two speakers and the listening position as an equilateral triangle. The third condition is that the inward projection angle of the two speakers is also 45 degrees or more. The fourth condition is that this regular triangle can be large or small. When the room is small and the power of the rear stage is not large, the square is smaller; when the room is large and the power of the rear stage is large, the triangle can be enlarged.
Effect: This is the so-called near-field approach. Its advantage is that it can reduce the excessive interference of the four walls of the reflected sound on the direct sound of the speaker, so it has a good positioning and a wide sound field. This is the most versatile, straightforward, and clearest detail. Many commentators like to use this method when evaluating sound.
Three, three seven seven proportional method: the length of the room is divided into three equal parts (three), the speaker is placed in the length of one third (a), the interval between the two speakers is two-thirds of the length of the room 0.7 times (seven). It is best to have a slight inward projection angle, but there is no inward projection, and the listening position should not be placed against the back wall.
Effect: This method is used for space with large size and uniform ratio (for example, 1:1.25:1.6 or 1:1.6:2.5), which can get balanced sound and wide sound field.
Four, three, three, one proportional method: the length of the room is divided into three equal parts (three), the width is also divided into three equal parts (three), the speaker is placed at the first equal point of length and width (a ). The speaker can have a slight inward projection angle, even without inward projection, and the listening position should not be placed against the back wall.
Effect: This method is also used for spaces with large size and uniform proportion. It is consistent with the spirit of the "Three-Seven Ratio Method". The only difference from the "Three-Seven-Seven Ratio Method" is the narrow spacing between the two speakers. This method also gives a balanced sound and a wide sound field.
Five, long back wall pendulum method: In a rectangular room, the general experience of playing audio, the short side of the speaker's back wall. However, this "long back wall pendulum method" is the opposite of the way, the long side is the back wall of the speaker. The speaker should leave at least 1 meter away from the back wall, and the distance between the speaker and the side wall should be at least half a meter. The distance between the two speakers is equal to the position of the listener, and the angle of the inward projection of the two speakers is at least 45 degrees. Listening to the location should not be attached to the wall, at least one meter away.
Effect: If you feel that the amount of low frequency in your sound system is not enough, then you can try the "long side wall swing method" that is now introduced. However, it should be noted that this kind of pendulum has a loss of sound. Although the sense of medium and low frequency is enhanced, the depth of the sound field will be a little worse, so to get a balance between them, It’s up to you to play slowly.
Sixth, the wall pendulum method: This is the oldest method. Put the speaker close to the back wall, whether it is 50 cm or 30 cm from the back wall, 20 cm, it doesn't matter, you can adjust it yourself. Usually the speaker does not need to project an angle inward.
Effect: When the high frequency is sharp, the intermediate frequency and the low frequency are weak, it can make the intermediate frequency and the low frequency full, and the whole high, medium and low frequency can be balanced. However, it also makes the depth of the sound field shallower and narrower. However, if you balance the sounds of squeaky sounds, it is a correct practice to sacrifice the sound field and seek a good sound.
Seven, rhombic pendulum pendulum method: This method is only used in square space. Think of the square space as a diamond, and the speakers are placed on the sides of the diamond against the wall. The diamond-shaped sharp corner behind the speaker and the diamond-shaped sharp corner behind the listening position should be subjected to arc or cylindrical sound wave diffusion treatment, and the second speaker should not be too close to the side wall.
Effect: This method deals with the problem that the square space of the square space is too strong. If the square space doesn't want to be like this, then you have to put in a lot of furniture to "settlement" the standing wave.
Summary: The seven most commonly used speaker pendulums are listed above, and you should be able to find one of the best pendulums in your general space. The principle of placing the speaker is that there will be a position in any living room space, a kind of pendulum method to make the most harmonious resonance effect between your speaker and the room, and the point that finds the best resonance effect is the best speaker we are pursuing. Placement. Therefore, the position of the speaker is not static; it is not necessary to use the ruler to be very accurate. If you feel that the above methods are not effective, then create your own way. After you have found a good location and a good way, please remember the specific position and placement angle, and then fine-tune, then the subtle movement of the speaker will become very sensitive, you can find the final after repeated fine-tuning. The best place to put it.
