How to place the speakers
How much does the speaker placement account for in the audio? If you ask me this way, my answer is: to make the sound sound, space conditions, equipment matching, speaker placement, and user fine-tuning Never. Among them, the speaker placement is a method that does not cost money but can make the sound of the speaker sound, so I am willing to say that the speaker placement is not accounted for 25% of the importance, but the importance of 50%. If you do n’t believe it, please try the positioning of various speakers carefully, and I think your idea will change by then.
Before telling you how to implement the "Position 8 Method", I will first reveal to readers an important concept, that is, "speaker and listening space are integrated". All kinds of sound performance are in the speaker and listening space Interaction between the two middle-class cattle. Or, I would like to say that the choice of space, speaker placement and listening position are three interactions, especially how bad the conditions of your quiet room are. The sound is good.
Here, in the "eight methods of speaker placement", I removed the original "top cabinet method" and replaced it with the "headphone placement method", so I still keep the 8 method.
The first method: three to seven ratio method
Method: divide the length of the room into three equal parts (three), place the speakers at one third of the length (one), and the interval between the two speakers is 0.7 times the length of two thirds of the room (seven). The speaker should preferably have a slight inward projection angle, but it can be projected without inward projection. The listening position should not be against the back wall. Effect: This method is used for spaces with large size and uniform ratio (for example, about 1: 1.25: 1.6 or about l: 1.6: 2.5), which can obtain balanced sound and wide and deep sound field. This is how the audio forum often recommends readers to try.
The second method: three three one ratio method
Method: Divide the length of the room into three equal parts (three), and the width into three equal parts (three), and place the speakers on the first equal point of length and width (one). The speaker can have a slight inward projection angle, even without inward projection, and the listening position cannot be against the back wall.
Effect: This method is suitable for spaces with large size and uniform ratio. It is consistent with the spirit of the "three to seven ratio method", the only difference from the "three to seven ratio method" is that the interval between the two speakers is narrow. This method can also obtain a balanced sound and a wide and deep sound field. The editor-in-chief of the American TAS magazine prefers this method.
The third method: screw hole pendulum method
Method Place the speakers between one-third and one-half the length of the room, and then put the two speakers against the wall as much as possible (if the room is very wide, you do not need to be close to the side wall). Greater than 45 °. The listening position should be between 0.5-1 meters after the intersection of the projected intersection.
Effect: This method treats the shortcomings of too high treble, too thin midrange and insufficient bass. Moreover, the best results can be achieved in the face of many harsh environments. This is an effective method provided by the "Sound Forum" for the general bad space.
Fourth method: regular triangle method
Method: The first condition is that the speaker should leave the back wall (at least 1 meter above) and the side wall (at least 0.5 meters above). The second condition is to draw the two speakers and the listening position into a regular triangle. The third condition is that the inward projection angle of the two speakers should also be 45 ° or more. The fourth condition is that the regular triangle can be large or small. When the room is small, the square is smaller when the power of the second stage is not large; when the room is large, the regular triangle is larger when the power of the second stage is large.
Effect: This is the so-called near sound field listening method. Its advantage is that it can reduce the excessive interference of the reflected sounds of the four walls on the direct sound of the speaker, thus obtaining a good sense of positioning and a wide and deep sound field. This is the method that can hear the most, the most direct and the clearest details. Many commentators like to use this method when evaluating sound. This is also the favorite arrangement of Venture Speaker Yang Heguangxi.
Fifth method: Long side fight
Method Put the speaker in the opposite direction, using the long side of the room as the back wall of the speaker, and the rest in accordance with the regular triangle swing method: the listening position should not be attached to the wall, at least a distance of one foot.
Effect: The mid-range and low-frequency volume sense will be enhanced, and the sound field depth will be poor. If the first to fourth methods are invalid, you can try to use it.
Sixth method: diamond pendulum method
Method: This method is limited to square space. Think of the square space as a diamond-shaped two-sided wall. The diamond-shaped sharp corner behind the speaker and the diamond-shaped corner behind the listening position should be subjected to cylindrical sound wave diffusion treatment. The second speaker should not be too close to the side wall.
Effect: This method specializes in the problem of too strong standing bass waves in square spaces. If the square space does not want to be placed like this, it is necessary to fill in a lot of furniture in order to "dry" the standing wave.
The seventh method: sticking to the wall
Method: This is the oldest pendulum method: Place the speaker close to the back wall, and it doesn't matter if it's 50cm, 30cm, or 20cm from the back wall. You can adjust it yourself. Usually the speakers do not need to project angles inward. Effect: Used when the high frequency is sharp, the middle frequency and the low frequency are weak, it can make the middle frequency and the low frequency full, and the entire high, middle and low frequency can be balanced. However, it also makes the depth of the sound field shallower and narrower in width. However, it can be weighed against harsh and unpleasant sounds, and it is the correct way to seek good sounds at the expense of the performance of the sound field.
The eighth method: the method of earphone pendulum method. First, the height of the listening position is that the ordinary single person sits on the sofa and the body is best against the back of the chair; second, the distance between the second speaker and the listener is sitting on the back , The distance between the two hands reaching forward and the middle finger just touching the inner edge of the second speaker is the most suitable; third, the two speakers need not project inward, and the correct position of the speaker is based on being able to hear the sound from "over the head"; fourth, the speaker The height, if it is a bookshelf type, it is better to be between 100-1l0cm after adding a tripod. If it's a floor-standing style, you can't pay attention to it,-cut the edge; fifth, the distance between the listening position and the distance to the wall is related, but it is best (perhaps-fixed) to have soft sound-absorbing materials; sixth, The space does not require additional sound processing arrangements. This kind of speaker swing method, because the effect you hear is similar to listening to music with headphones, and the left and right speakers are also close to the two ears, so I call it the "headphone swing method."
The effect is like listening to music with headphones, and it is almost not affected by space conditions. The sound originally located in the center of the sound field becomes above the head, and the sound originally left and right is still left and right. In addition, the overall sound details and various performances have become clearer and sharper, and the shock power of low frequencies and the clarity of particles are unparalleled. Compared with the general pendulum method, the low-frequency sound range seems to be a dwarf into a giant.
The above “eight methods of pendulum†are the eight most commonly used speaker placement methods. In the general space, you should be able to find one of the most suitable pendulum methods: Nevertheless, I have to remind you of two things. The positioning of the speaker is not static; it is not necessary to use a ruler to measure it very accurately. If you feel that the above eight methods are all unpleasant, don't be polite, please come up with a different way of doing it yourself. The placement of the speakers is endless, and the beauty of the application is completely focused. Second, "When you find a good location and a good way, the slight movement of the speaker will become very sensitive." At this point, you have to fine-tune the work. Finally, once again, the first principle of thinking that you should grasp when arranging the speakers is: there will be a position in any room, a kind of pendulum method will let your speakers and the room emit the most harmonious resonance effect, and find the best resonance effect That point is the best placement of the speakers we pursue.
In addition to the traditional two-channel swing method, there are different swing methods for multi-channel DVD-Video and multi-channel DVD-Video or SACD. Recommend a multi-channel pure audio speaker placement method, that is, the center of the listening position, the left front, center, right front, left rear, right rear five speakers should be the same size, and the distance from the listening position should also be the same. The angle between the front left speaker and the center axis is 30 °, the middle channel is of course 0 ° from the center, and the angle between the right front speaker and the center axis is also 30 °. The speakers are not placed on both sides of the listening position, and the left rear speaker forms an angle of 110 ° with the central axis. This kind of pendulum is good in theory, but it is difficult to do it in practice. Unless there is an exclusive room, few people can let you do this in your home.
