At present, there are various brands of speakers on the market, and there are many brands of miscellaneous products. How do you choose the various speakers with different quality? Everyone knows that the sound of the current speakers is composed of treble and bass. Many brands advertise that the bass effect of their products is shocking, so how can we tell if it is good or bad? First, test the quality of low frequency The low frequency produced by inferior speakers is screaming, bloated and loose, lacking layering and solidity. Good low frequency should be clean and bright, well-defined, and will not drag the water, even a variety of low-frequency instruments such as the size of the drum sound, bass guitar and piano bass can be easily distinguished. So don't be fooled by the low-frequency sense, the inferior low-frequency is not as comfortable as the clean sound. Second, test the IF vocals Vocals are the most commonly heard voices. The pros and cons are not difficult to detect. Pay attention to whether the vocals have unusual nasal sounds or the feeling of being snorted. The "box sound" of some speakers will also greatly interfere with the intermediate frequency, making the sound of this band ambiguous. IF sound is more serious than other frequencies, because most of the audible frequencies, or the frequency of the music, are concentrated in the mid-range, which is a replay for almost all types of music. Obstacles. Third, test the high frequency flexibility Fourth, test high volume and sound field image Some speakers are stable at low volume, but they are distorted when the volume is raised to an index, or “shootingâ€, and various non-recorded music signals appear. The standard-compliant speakers make the sound out of the box to a certain extent, creating a clear sound field and image, showing the position and texture of the different instruments, and there is sufficient diffusion. The mute and the tail should be clearly heard, and in the case of large volume and "big burst" without distortion, the vocals and instrumental sounds will not be entangled.
Inferior high-frequency is screaming, hearing people have a splitting headache, and in extreme cases, the vibrating sound of the violin or soprano becomes the sharp noise of the brakes. Similarly, the different textures produced by different instruments in the treble, the good treble can be distinguished. The high frequency of the superior level can even distinguish the different phonographs played by two different woods of different years.
The easiest thing to master is that a good high-pitched sound will not be audible, the pores will be erected, and it will not be more and more tiring, and it will be soft, flexible, smooth and layered. The highest point is still easy to hear but does not produce a change (of course not based on the recording of the singer).
The high-quality replay can show a rich sense of music and air, and the bounce of the notes, like the clouds and see the sky, showing the whole sequence of audio and video. More directly, it will not be exhausting when you listen for a long time.
