A brief discussion on the placement of speakers

In the audio equipment, how much does the speaker position account for? Want to let acoustics good sound, the collocation of space condition, equipment, sound box is placed and the 4 major items such as fine adjustment are short of one cannot. Among them, the speaker positioning is not need to spend money but can make the sound good method, so that the speaker positioning is not 25% of the importance, but 50% of the importance. If you don't believe me, please carefully try out various ways of positioning the speakers, and I think you will change your mind then.

Before telling how to carry out the "8 positions", we should first reveal an important concept, that is, "the speaker and the listening space are one", the various manifestations of sound are generated in the interaction between the speaker and the listening space. Or, more importantly, the choice of space, speaker positioning and listening position is the interaction of the three, no matter how bad your space conditions are, if you can find the best balance among the three interactions, you can make the sound sound good.

The first kind: 317 proportion method

Methods: The room length was divided into three equal parts (three), the speakers were placed at one third of the length (one), and the interval between the two speakers was 0.7 times the length of two thirds of the room (seven). The speaker should have a slight inward projection Angle, but no inward projection is possible. The listening position should not be attached to the back wall.

Effect: This method is applied to the space with large size and uniform proportion (for example, about 1:1.25:1.6 or about L: 1.6:2.5). It can obtain a balanced sound and a wide and deep sound field. This is often recommended in the audio industry.

The second kind: ratio of three and three

Methods: The room length was divided into three equal parts (three), and the width was also divided into three equal parts (three). The speaker was placed on the first equal part of length and width (one). The speaker can have a slight inward projection Angle, even without inward projection, and the listening position should not be against the back wall.

Effect: This method is suitable for the space with large size and uniform proportion. It is consistent with the spirit of the "317 proportion method", the only difference with the "317 proportion method" is that the interval between the two speakers is narrower. This method also produces a balanced sound and a wide and deep sound field.

The third kind: screw hole pendulum method

Method: place the speakers between one third and one half of the length of the room. Then place the two speakers as close as possible to two over the walls (if the room is wide, it is not necessary to lean against the side wall). The inward projection Angle of the two speakers should be greater than 45°. The listening position should be between 0.5 and 1 meters after the intersection point of the projected cross line.

Effect: This method is specially for the shortcomings of treble too sharp, tenor too thin and bass not enough. Moreover, the best results can be obtained in the face of many harsh environments. This is the "sound industry" for the general bad space provided by the effective pendulum method.

Fourth: equilateral triangle method

Method: The first condition is that the speaker should be away from the back wall (at least 1 meter above) and the side wall (at least 0.5 meter above). 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 both speakers should also be 45° or more. The fourth condition is that this equilateral triangle can be large or small. The room is small, and the square is smaller when the power of the rear stage is not large. The room is big, the equilateral triangle is bigger when the power of the rear stage is big.

Effect: This is commonly known as the near field listening method. It has the advantage of reducing the excessive interference of the four wall reflections on the direct sound of the speaker, thus obtaining a good sense of positioning and a wide and deep sound field. This is the most audible, most direct, the most clear details of the pendulum method. Many audiophiles often use this method when evaluating audio systems.

The 5th kind: long side pass method

Method: put the speaker in the opposite direction, take the long side of the room as the back wall of the speaker, the rest according to the equilateral triangle pendulum: the listening position should not stick to the wall, at least leave a distance of a ruler.

Effect: If and low frequency sense will be enhanced, the depth of sound field will be poor. If the first to fourth methods are not working, try using them.

Sixth: the diamond pendulum method

Methods: This method is only used in square space. Think of a square space as a place against a wall on either side of a diamond. The rhombic Angle behind the speaker and the rhombic Angle behind the listening position should do cylindrical sound wave diffusion processing, two speakers should not be close to the side wall.

Effect: This method is specially used to solve the problem of too strong standing wave of bass rumble in square space. If the square space doesn't want to swing this way, it has to cram a lot of furniture into it in a "dry rest" mode

Seventh: stick wall pile method

Method: This is the oldest pendulum method: put the speaker close to the back wall. It doesn't matter if it is 50cm or 30cm or 20cm away from the back wall. Usually speakers do not need to project an Angle inward.

Effect: high frequency sharp, medium frequency, low frequency weak use, can let if and low frequency full up, the whole high, medium and low frequency can be balanced. However, it also makes the depth and width of the sound field smaller. But, weighed against the harshness of the sound, it is right to sacrifice field performance for pleasant sounds.

The 8th kind: earphone is placed method

Method: the first, listen to the position height with average single person to sit on the sofa, the body leans back on the height of the chair best; Second, the distance between the two speakers and the listener should be to sit on the back of the listener. The distance between the two speakers and the middle finger just touching the inner edge of the two speakers is the most suitable. Third, the two speakers do not have to be projected inward. The speakers should be placed in the correct position so that the sound can be heard from "overhead". Fourth, the height of the speaker, if it is a bookshelf, plus after the foot frame in 100-1l0cm for the better. If it is the landform that can not pay attention to, - cut with the edge; Fifth, listen to the position behind the wall from how far and how close to the relationship, but it is best to have soft sound-absorbing material processing; Sixth, the space does not need to do more sound processing layout. This kind of speaker is placed, because the effect that hears is similar to wear earphone to listen to music, and the left and right two speakers are also close to two ears, so it is called "earphone is placed".

Effect: Like listening to music on headphones, it is almost unaffected by spatial conditions. The sound that was in the middle of the sound field becomes above the head, and the left and right sounds remain left and right. In addition, the overall sound details and various performances become clearer and sharper, and the power of the low-frequency sound and the clarity of the particles are unmatched, compared with the normal swing, the low-frequency sound domain looks like a dwarf turned giant.

The above "pendulum" is one of the eight most commonly used ways to position speakers, and in general space you should be able to find one that works best for you: nevertheless, still
