1. The relationship between the horn and the listener wants to make a snoring. The distance between the listening position (commonly known as "the emperor's position") and the horn should be larger than the distance between the two horns. Here, the instrument has a knot image. The force and sound are best. As for the distance between the two speakers, there is a compromise. When the two speakers are too close, the sound field is too narrow. When the listening position is well placed, the middle audio image is the best, and at the same time there is a wide sound field. You can move the emperor forward and listen to it. Most of them will find a position to hear the 定ä½"positioning". Recording as a guideline.
The relationship between the horn and the emperor also involves the room factor. You can pull the horn very close and sit close to the horn to listen, but you can also pull the horn very open and sit very far to listen, if you use it In the way, the room will have a greater impact on the sound, because the closer you sit, the more direct sound you hear and the less the reflected sound. In general, the more you sit, the more open you will listen. The closer you get, the more direct the sound is to the ear. Some speakers want you to sit farther to listen, so that the sound of different units of the speaker can be gentle. Welcome to China Home Theater Network
2. The closer the speaker is to the wall, the more the bass is. The wall around the room has a great influence on the overall tone balance of the speaker. The speaker near the wall will strengthen the bass, making the music replay more weighty. Some speakers are designed to be close to the wall. Natural tone balance, if you pull them out, the sound will be thinner, and some speakers will be at least 3 feet away from the wall, otherwise the sound will become thick and heavy. If you have restrictions on positioning, buy a speaker. There should be a choice.
When the speaker is close to the wall, the bass energy hits the wall and is reflected back into the room, so the bass is enhanced. Table 1 shows the frequency of the speaker in the non-reflecting room and the normal room. You can see that the bass is not only more, but also It also stretches lower, and the speaker is close to any wall (underground, back wall, side wall) to enhance the low frequency. The closer the speaker is to the corner, the more bass you hear.
The relationship between the horn position and the wall also affects the peak point of the frequency. The position of the horn is well placed, which not only allows the frequency of the horn to naturally extend, but also avoids the occurrence of valley peaks. If the position is not good, the low frequency will be rendered.
Many horn manufacturers have proved that the product should be away from the back wall and side wall. The more the side wall you hear, the more harmful it is. This is harmful if the side wall is treated with tuning materials. Of course, the side wall reflection sound is not so serious. It is.
3, different speakers and listening position, will hear different resonant modes Room resonance mode refers to the peak value of some frequency bands, or "standing wave" that is, a certain bass frequency band is extremely strong, so that the sound has a diarrhea, the mode of standing wave Depending on the size of the room and the location of the pronunciation point, as long as the speaker and listener are placed in the best position, the bass will be more rounded.
According to the actual experience, in order to obtain the best low-frequency response, the distance between the horn and the back wall should be one-third of the length of the room. If this is not feasible, try one-fifth of the length of the room. Each position can cause a standing wave to help the speaker to be combined with the room. If possible, the listening position is preferably two-thirds of the length of the room.
Start with the above method, play some music with a lot of bass, then shift the speaker and the emperor step by step (one inch and one inch) until you hear the bass stretch smooth and mix with other frequency bands, when you hear the bass is the most sleek At the same time, it will be noticed that the clarity and analytical power of the midrange have also improved.
4. The distance between the horn and the back wall affects the performance of the sound field. Generally speaking, the farther the horn is from the back wall, the deeper the sound field is. It is difficult to create a deep sound field when the horn is close to the back wall. Pull the horn out a few feet. The difference in sound field performance is like heaven and earth. Unfortunately, many living rooms are impossible for you to pull the horn very close. If you must put the horn on the back wall, you should make appropriate sound absorption on the wall. .
5. Listening height and tone balance Most of the timbre balance will change with the listening height, but only the midrange and treble, the same height of the tweeter or the two tweeters will be located 32 inches off the ground. Between 40 inches, to match the listening height of the average person, if you sit under the office chair that can adjust the height, you can easily hear the difference. Listening to the high impact of the sound effect, depending on the different speakers, some speakers have a lot of tolerance, the distinction is not so obvious, and some have significant differences, you can hear different voices when you stretch out, want to get good For the balance of the sound, please use one to sit on the same level as the tweeter.

6, horn intrusion (Toe-in)
In contrast to the speaker balance, the intrusion of the speaker is another way of positioning. However, there are no rules. The number of speakers depends on the speaker and the listening environment. Some speakers need to break in. Some need to be flat. The speakers can affect the sound in many ways, including the middle and high notes. Image, space and pressure.
Most of the speakers hear the highest treble in the triangle listening position, so they will receive more high-pitched energy when they enter the horn, so some horns that are too bright will hear too much treble in the toe-in.
Toe-in also affects the ratio of direct and reflected sounds that you hear. When the horn is in, the main sound energy will be directed at the listener. If the wall of the room is strong, the horn will be inserted into the room. The advantage is that the side wall will have less reflection. Conversely, reducing the Toe-in angle will make you hear more reflections, but it will also give you a better sense of space and a wider sound field. Similarly, toe-in can improve the image-forming power. Many speakers can have better sound field performance in toe-in, and the audio image is more stereoscopic. The best toe-in angle is often a compromise. Toe-in is too long, the sound field is sturdy, but the treble is too much. When there is no toe-in, the treble is smooth, but the middle image is more vague and the sense of space is the same. When the speaker is flat, the sound field is wide and open, but it is not precise enough. After the toe-in, the sound field is narrowed, but the image is better. In short, the toe-in depends on the speaker, the room and personal taste, the only one. The solution is to constantly shift and listen.
It is very important that the two speakers have the same angle toe-in. The easiest way is to measure the distance from the back wall to the back of the horn. Another way is to look at the toe-in angle of the horn from the emperor's position. You can determine the toe-in angle of the two horns by looking at the side of the horn.
Speaker placement summing up the speaker position is the best way to improve the sound effect, it can increase your ability to distinguish the sound quality without spending money, and can make the ordinary effect become excellent (even if the equipment and the speaker are unchanged), Before you spend money to upgrade your equipment or perform sound-absorbing projects, please make sure that you have used the speakers to make the most of the system's potential.
After you find the best position for the horn, you need to add the nails supplied by the manufacturer. The four (or three) nails should bear the same weight, so that the horn test can stand still and will not swing left and right. We can control the sound effect through the speaker position. Changing the distance of the speaker to the back wall or side wall can control the low frequency quality. Changing the position of the speaker and the listener can reduce the influence of room resonance. The high-speed listening height and the toe-in angle can be Improve the tone balance, change the toe-in angle to easily change the image and space, and pull the speaker away from the back wall to increase the depth of the sound field.
The horn placement is the best way to get the hum, and it doesn't cost you half a penny. Please try to shift.
