How does Dongguan horn factory distinguish between good and bad speakers? Televisions, radios and tape recorders used in our daily life have loudspeakers, commonly known as loudspeakers, which convert electrical signals into sound signals. Although any speaker has its strengths and weaknesses, especially under a limited budget, how to select a group of super value speakers is a major knowledge. Speaker manufacturers tell you that there are certain reference standards or directions for speakers at any price and level.

1、 Test the quality of low frequency
The low frequency produced by inferior speakers can be as loud as deaf, but it is completely bloated, loose and thick, lacking a sense of hierarchy and firmness. A good low-frequency instrument should be clean, lively, well-organized, and not muddy. Even various low-frequency instruments such as big and small drums, bass guitar and Piano bass can be easily distinguished. So don't be easily fooled by the low-frequency sense of quantity,
Inferior low frequency is not as natural and comfortable as a clean sound. Some bookshelf AV speakers boasting heavy two tone channels, many buyers will think it is very valuable, because people will screw the weight first when choosing the speaker, because some so-called "experts" said that the heavier the speaker, the more valuable it is. In fact, this is right or wrong. Generally, old enthusiasts want you to screw the weight,
According to the weight of the loudspeaker, the dense board (MD) of the box is thick, and the board is thick, so it is not easy to produce resonance; In addition, the magnet of the subwoofer unit of the speaker is large, so the bass presented is heavy. However, it is estimated that the weight of a bookshelf speaker with an average height of 38 cm should be considered heavy at 6 or 7 kg. If it exceeds this weight by a lot, and the body is even as high as 30 or 40 kg, its weight may be a gimmick, which will not help the overall sound quality.
2、 Test if vocal
Human voice is often heard, and its advantages and disadvantages are not difficult to detect. Pay attention to whether the human voice has an unusual nasal sound or the feeling of being pursed. The "box sound" of some speakers will also greatly interfere with the if, making the sound of this frequency band blurred. If noise is more serious than other frequencies, because most of the audible sound frequencies,
Or the frequency of music is concentrated in the intermediate frequency range, which will become an obstacle to playback for almost all kinds of music.
3、 Test the flexibility of high frequency
The poor high frequency is the sharp sound in the ear, which makes the head ache and crack. In extreme cases, it turns the beautiful sound of violin or soprano into the sharp noise of braking. Similarly, different instruments in the treble produce different textures, and a good treble can be distinguished. Another level of high frequency can even distinguish two different phonology played by different wood in different years.
The key to be easy to master is that a good treble will not be frightening to listen to, and the pores will not stand up, nor will it make people more and more tired to listen to. Moreover, it should be soft, flexible, smooth and hierarchical. It can still be easily heard from high places, but there will be no sound change.
4、 Test high volume and sound field image
Some speakers are stable in bass volume, but when the volume increases to a certain index, it will be distorted, or "beat edge", and various non recorded music signals will appear (of course, the volume of no more than 12 o'clock is the safe test standard). Specifically, if orchestral music is one of the favorite music, it must pass this pass.
The standard speakers can separate the sound from the box to a certain extent, create a clear sound field and image, and show the split point position and texture of different musical instruments.
There is enough diffusion to meet the existing listening space. The weak sound and tail sound should be clearly heard. There is no deformation and distortion in the case of high volume and "big explosion", and the voice of human voice and musical instrument will not be entangled. High quality playback can show a rich sense of music and air, as well as the bouncing power of notes, like pulling out the clouds to see the blue sky, showing the whole detailed and orderly audio and video. More directly, it won't make your ears tired after listening for a long time.
