Home theater network () Many people are not satisfied with the sound of their own system. In this case, many people's ideas are to upgrade and replace equipment. Here I would like to talk about my personal experience and opinions on this situation, as well as some American TAS speaker magazines. The article will be divided into two parts, the upper part is about the importance of speaker placement and some basic concepts, the lower part will explain in detail the actual combat, specifically which CD record to put the speaker into the best position (maybe just me The best position in the ear).
In many people's audio-visual rooms, the system does not produce a satisfactory sound. The most important and basic problem is that the speaker is not placed correctly. Finding the correct position for your speaker is the most important basic factor for the system to make a good sound. At the same time, the most worthwhile thing is that it doesn't cost you a penny. It just takes your time and can greatly improve the system's expressiveness. This is to upgrade your system performance with the best price/performance ratio. When the speaker position is not correct, don't misjudge which piece of equipment is good or bad, because you can't hear it correctly. Improper placement of the speakers can result in significant staining and distortion of the entire system. Only when the speaker emits the most (or close to) flat frequency response in the listening room, can we correctly judge the performance of the front-end equipment. Therefore, the correct speaker placement is the problem that our enthusiasts should take seriously and think correctly, instead of changing the equipment easily. Improving the performance of the system is often based on our tuning methods rather than on money. Without the right tuning method, you will never be able to get close to the best performance of the system, even if you have expensive equipment. Speaker placement is the top priority of tuning, and there is no conflict with your listening preferences (flavors).
Which factors can affect the system? It affects the system's most important balance (high, medium, and low-pitched coordination). The amount and quality of the bass, the width and depth of the sound field, the clarity of the midrange, and the pronunciation. And audio and video, the smoothness and extension of the treble, the overtone, the sense of space and the systemic vibrancy. After understanding the importance of the above speakers, let's take a look at the specific basic requirements.
1: The relationship between the speaker and you is the most important. The emperor should be triangular between the two speakers. The listener should sit in the middle of the two speakers, and the distance from the speakers should be slightly larger than the distance between the two speakers. Set the distance between the two speakers, and then repeat the audio and video between the wide sound field and the clear center audio image. The wider the sound field is, the wider the sound field is. If the speaker is turned on, the middle image will be weakened or even disappear. If the speaker spacing is too narrow, the sound field width will shrink. When using multi-unit speakers, you should try to be farther away from the speakers, so that the sounds of the various units can be fused together. If the distance is too close, the coordination of high, medium and low sounds will be very different. Without this basic configuration, you will not be able to hear good sound stages and images.
2: The amount of bass is affected by the proximity of the wall. The closer the speaker is to the wall and the corner, the more the bass feels. Here, let me first mention whether your speaker is a bass reflex or a sealed speaker. The bass reflex type must be kept away from the back wall, and the sealed speaker is not limited. If your room has limited speakers and you can't stay away from the back wall, make sure you choose which one is right for your room. Some speakers are designed to be close to the back wall to enhance the bass to achieve the natural coordination of high, medium and low sound. If these speakers are close to the center of the room, the sound will become thinner. Proper placement, not only can extend the low-frequency response of the speaker, achieve natural attenuation, but also avoid the peaks and dents of the frequency, making the bass smoother. Improper placement can cause uneven frequency response and render bass. As a result, the bass will be enhanced, medium and low. The distance between the horn and the side wall will affect the reflection of the sound. The closer to the side wall, the more the reflected sound will reach the listener. This is not a good thing, it will affect the positioning of the image.
3: The distance from the back wall affects the expressive power of the sound field. Usually, the farther the horn is from the back wall, the deeper the sound stage. Deep and wide sound fields are rarely produced on speakers close to the back wall. Unfortunately, there are many audio-visual rooms that cannot move the speakers away from the back wall. If the speakers must be close to the back wall, the back wall should be diffused. I basically don't quite agree to lean the seat of the speaker toward the back wall, because it is easy to make the depth of the sound field shallower, and it is easy to make the sound worse.
4: The position of the listener in the room. When you hear the resonance in the room, you should constantly move the listening chair back and forth to find the best seat without resonance. When you find the flattest position, you get a smoother bass, and you can hear the midrange clarity and resolution improvements.
5: Listen to the harmony between height and high school bass. When the seat height changes, it will affect the high school bass, not the balance of the bass. Specifically, when your ears are at the same height as the tweeter, or on the tweeter axis, the speaker sounds the brightest (the highest amount of treble). The degree of change due to the high level of sound varies greatly from speaker to speaker. Some speakers have a lot of tolerance, and when you change the height, you can only listen to small differences. Choose the right listening chair to make your ears the best axis for your best treble balance.
6: The angle of the speaker is adjusted. The internal adjustment angle is to point the speaker unit directly to the listener. There are no rules for the internal adjustment angle. Some speakers need to adjust the angle internally, and some are best facing forward. The internal adjustment angle affects many aspects of music performance, including the balance of middle and high notes, the focus of the sound stage, the sense of space and direct sound. Most of the speakers have the loudest sound when they are directly on the axis. Excessively bright speakers can often be tamed with a horn forward. When the width of the room is insufficient, the angle adjustment is obviously beneficial because the reflected sound of the side wall is greatly reduced due to the angle adjustment. Conversely, the angle is adjusted internally, and the reflected sound is used to enhance the sense of space and air. The best internal adjustment angle is often too high in treble, and exchange adjustments with accurate central audio and video. Too many angles adjust the sound to a good focus, but the sound is often too bright. There is no angle adjustment, the treble is smoother, but the sound image positioning is more blurred. The amount of angle adjustment is determined by the speaker, room, and personal preference. However, the angle of each speaker must be the same, which is very important, because the same frequency response from the two speakers, accurate positioning of the audio and video in the sound field, can be said to be an important enabler, WeChat: cnhifi.
