1. Three-one-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), two The spacing between speakers is 0.7 times (seven) two-thirds of the length of the room. It is best for the speakers to have a slight inward projection angle, but no inward projection is acceptable. The listening position should not be against the back wall. Effect: This method is used in spaces with larger sizes and even proportions (for example, about 1:1.25:1.6 or about 1:1.6:2.5) to obtain balanced sound and a wide and deep sound field.

2. 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 At the first equal intersection point of length and width (1). The speakers can have a slight inward projection angle, or even do not need to be inward projection, and the listening position should not be against the back wall.

Effect: This method is suitable for spaces with larger sizes and even proportions. It is consistent with the spirit of the "31-7 ratio method". The only difference from the "31-7 ratio method" is that the distance between the two speakers is narrower. This method can also achieve balanced sound and a wide and deep sound field. The editor-in-chief of American TAS magazine likes to use this method.

3. Screw hole placement method

Method: Place the speakers between one-third and one-half of the length of the room, and then place the two speakers as close to each other as possible over the wall (such as If the room is very wide, it does not need to be close to the side wall), and the inward projection angle of the two speakers should be greater than 45°. The listening position should be between 0.5 and 1 meter behind the intersection point of the projection cross lines.

Effect: This method is designed to cure the shortcomings of too sharp treble, too thin midrange and insufficient bass. Moreover, the best results can be achieved when facing many harsh environments. This is an effective arrangement method provided by the "Audio Forum" for generally bad spaces.

5. Equilateral triangle method

Method: The first condition is that the speakers should be away from the back wall (at least 1 meter away) and the side wall (at least 0.5 meters away) . The second condition is to draw the two speakers and the listening position into an equilateral triangle. The third condition is that the inward projection angle of the two speakers must also be 45° or more. The fourth condition is that this equilateral triangle can be large or small. If the room is small, the square will be smaller when the power of the downstream stage is low; if the room is large, the equilateral triangle will be larger when the power of the downstream stage is high.

Effect: This is commonly known as near sound field listening. Its advantage is that it can reduce the excessive interference of the reflected sound from 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 way to hear the most, most direct, and clearest details. Many commentators like to use this method when reviewing audio.

5. Long side placement method

Method: Place the speakers in the opposite direction, with the long side of the room as the back wall of the speakers, and the rest according to the equilateral triangle placement method: the listening position cannot be against the wall , keep at least one foot of distance.

Effect: The mid-frequency and low-frequency volume will be enhanced, and the sound field depth will be poor. If the first to fourth methods are ineffective, you can try this.

6. Diamond pendulum method

This method can only be used in square spaces. Think of a square space as a rhombus with two sides against the wall. The rhombus sharp corners behind the speakers and the rhombus corners behind the listening position need to be treated with cylindrical sound wave diffusion. The second speaker should not be too close to the side wall.

Effect: This method is designed to solve the problem of too strong standing waves of bass boom in square spaces. If the square space does not want to be arranged like this, a lot of furniture must be crammed in to "break" the standing waves.

7. Sticking to the wall method

Method: This is the oldest placement method: place the speaker close to the back wall. It doesn’t matter if it is 50cm, 30cm or 20cm away from the back wall. You can do it yourself. Just prepare. Speakers generally do not require an inward projection angle. Effect: Use it when the high frequency is sharp, the mid frequency, and the low frequency are weak. It can make the mid frequency and low frequency fuller, and the entire high, mid, and low frequencies can be balanced. However, it will also make the depth of the soundstage shallower and the width narrower. However, it can be weighed against the harsh and unpleasant sound, and it is the right approach to sacrifice the performance of the sound field for good-sounding sound.

8. How to place headphones

The best listening position is the height of an ordinary single person sitting on the sofa and leaning on the back of the chair; second, the distance between the speaker and the listener The most suitable distance is when the listener is sitting with his back, his hands stretched forward, and his middle finger just touching the inner edge of the two speakers; the two speakers do not need to be projected inward, and the correct position of the speaker should be that the sound can be heard from the "top of the head"; the speaker The height, if it is a bookshelf type, is preferably between 100-1l0cm after adding a tripod. If it is a floor-standing type, then you can’t pay attention to it, just let it happen; fifthly, it depends on how far or close the listening position is to the wall, but it is best (perhaps must) be treated with soft sound-absorbing materials; the space does not need In addition, do more sound processing arrangements. This method of speaker placement is called the "headphone placement method" because the effect you hear is similar to listening to music with headphones, and the left and right speakers are almost close to the two ears.
