How to "make the sound more beautiful and pure" is very important for the placement of speakers. In fact, the sound quality is mainly affected by four factors: space conditions, equipment collocation, speaker placement and user fine-tuning. When the equipment is ready, whether the "beautiful sound" can be placed depends on the position, which will affect the timbre balance, low-frequency quality, sound field depth, IF clarity and imaging power. Because all kinds of performance of sound are produced in the interaction between speaker and listening space, as long as we find a good balance between space, speaker placement and listening position, we can make the sound "beautiful".
1. The relationship between sound and listener
If you want to be "beautiful", the distance between the listening position (commonly known as "emperor's throne") and the sound should be larger than the distance between the two speakers. At this distance, the instrument has the binding power and the sound* is good.
So, the question arises, how far should the distance between the two speakers be? There is a compromise in it, and you need to "locate" yourself. When the listening position is well placed, the middle audio and video is good, and there is a wide sound field. When you move forward and backward to listen, most of you will find a position where you can hear beautiful "positioning". When auditing, you can use some clearly positioned recording in the middle as a criterion.
Sound and "emperor's throne" also involve room factors. You can pull the sound very close. People can listen very close to the sound. They can also pull the sound very open. People can also listen very far away. If you use the latter method, the room will have a greater impact on sound, because the closer you sit, the more direct sound you hear and the less reflective sound you have. Generally speaking, the farther you sit, the more open your voice will be. The closer you sit, the more direct your voice will be to your ear. Some sounds require you to sit farther away to listen so that the sound will not be heard. The sound of the same unit can be gentle.
2. The closer the sound is to the wall, the more bass.
The wall has a great influence on the overall timbre balance of the sound. The sound near the wall will strengthen the bass and make the music more weighty. Sound near any wall (underground, back wall, side wall) will enhance the low-frequency volume, the closer the sound is to the corner, the more bass you hear. The relationship between the sound placement and the wall also affects the peak point of the frequency. A good placement not only makes the frequency of the sound extend naturally, but also avoids the peak. If the position is not good, the low frequency will be rendered.
Some acoustics are designed to achieve a natural timbre balance close to the wall, otherwise the sound will be thin; while some acoustics require a certain distance from the wall, otherwise the sound will become thick and heavy. Therefore, at the beginning of purchasing audio, you should make a choice according to your actual situation and habits.
3. Achieving * Good Resonance Mode
The room resonance mode depends on the size of the room and the position of the pronunciation point. As long as the sound and listening position are * good, the bass sounds very smooth.
Generally speaking, in order to get a good low-frequency response, the distance between the sound and the back wall should be one third of the length of the room. If not feasible, you can try one fifth of the length of the room. Both positions can trigger standing waves to help the sound combine with the room. The listening position * is good for two-thirds of the length of the room. In this way, you can play a lot of bass music, and then gradually shift the sound and the listener until you hear the bass stretching smoothly and mixing with other frequency bands. When you hear the bass * smoothly, you will find that the clarity and analytical power of the baritone has also improved.
4. The Distance Between the Audio and the Rear Wall
Generally speaking, the farther away the sound is from the back wall, the deeper the sound field is. It is very difficult to create a deep and wide sound field when the sound is close to the back wall. If the sound is pulled out a certain distance, the sound field performance is extremely different. Unfortunately, due to limited conditions, many rooms do not allow you to pull the stereo very close. So, what to do? Make proper sound absorption treatment on the wall!
5. Listening Height and Timbre Balance
The timbre balance of most speakers varies with the listening height, but the change is in the mid-tone and the treble. The treble units at the same height or at two treble units are mostly between 32 and 40 inches from the ground. You might as well sit in a chair and adjust your height to listen to the difference. The degree of sound effect depends on different sounds, some of which have a large tolerance difference is not so obvious, while others have a significant difference. The direct way to achieve good timbre balance is to keep the ear treble on the same level.
6. Toe-in
Sound placement is another way of placement. It has many effects on sound, including high pitch, sound field image, space sense and pressure. But there is no rule to say. The amount of sound input depends on the sound and listening environment. Some sound needs to be put in, while others need to be swing flat. Most stereos hear more treble * in the triangle listening position, and when the stereo crashes, it receives more treble energy, which leads to some stereos hearing too much treble when they crash in.
Input also affects the ratio of direct sound to reflected sound. The main sound energy will be directed to the listener when it falls in. If the wall of the room rebounds strongly, the reflection sound of the side wall will be less. It is obviously beneficial to pour the sound into the room. On the contrary, the angle of convergence can produce more reflective sound, but it can also get a better sense of space and a wider sound field. Similarly, incorporation can improve the resultant image power. Many audio systems have better sound field performance in incorporation, and the audio and video are more stereo and clear. The effect of the angle is two-sided. For a long time, the sound field is beautiful enough, but there are too many tenors. Without the angle, the tenor is smooth, and the middle knot is vague again. The same is true for the sense of space. When the sound is flat, the sound field is wide, but not *. After entering, the sound field is narrowed, but the image is better.
In a word, the amount of input depends on the sound, room and personal taste. The way of * is to shift constantly and listen constantly. It is very important that the angles of the two speakers are the same. * The simple way is to measure the distance between the back wall and the back of the sound, and then measure the other side after measuring. The other way is to observe the angle of the sound from the "emperor's throne", depending on how much you see the side of the sound box, you can decide whether the angle of the two sound boxes is the same.
