1. Test the quality of low frequency
The low frequencies produced by inferior speakers can be deafening, but it is completely bloated and lacks a sense of hierarchy and solidity. A good low frequency should be clean and bright, with distinct layers, and it will not drag on the mud and water, and the injustice will not be scattered, even if various low-frequency instruments such as large and small drums, bass guitar and piano bass can be easily distinguished. So don't be easily fooled by the sense of volume of low frequency, inferior low frequency is not as comfortable as clean sound.
2. Test the mid-range vocals
Vocals are the most commonly heard voices. It is not difficult to detect the pros and cons. Pay attention to whether the vocals have unusual nasal sounds or the feeling of being squeezed. The "box sound" of some speakers will also greatly interfere with the intermediate frequency, making the sound in this frequency band unclear. Intermediate frequency dyeing is more serious than other frequency dyeing, because most of the audible sound frequencies, or music frequencies, are concentrated in the intermediate frequency range. This is a replay for almost all types of music. Obstacles.
3. Test the high-frequency flexibility
The inferior high-frequency is sharply inserted into the ear, and people can hear headaches. In extreme cases, the beautiful sound of the violin or soprano is turned into the sharp noise of the brake. Similarly, different instrumental music in treble produces different textures, good treble can be distinguished. The high frequency of a good or bad level can even make people distinguish the different rhymes played by two different woods of different years. The easiest thing to grasp is that a good treble is not daunting to hear back, the pores are erected, it will not make you more tired, and it should be pliable and elastic, smooth and layered, It can be easily heard up to the highest point, but it will not change the sound (of course not based on the recording of the walking singer)
4. Test high volume and sound field imaging
Some speakers are stable at low volume, but when the volume is increased to a certain index, it will be distorted, or "beating", and various non-recorded music signals appear (of course, a volume of no more than 12 points is a safe test standard ). Specifically, if orchestral music is one of the favorite types of music, you must pass this level. To a certain extent, the standard speakers can make the sound off the box, creating a clear sound field and knot image, showing the location and texture of different musical instruments, with sufficient diffusion to grow, wide, high but high-quality audio space. Weak sounds and tail sounds should be clearly heard, and in the case of large volume and "big explosion", there is no distortion and distortion, and human voices and instrument sounds will not be entangled. High-quality replays can show a rich sense of music and air, and the bounce of the notes, just like the clouds and fog to see the blue sky, showing the entire detailed and orderly audio image. And more directly, it won't make your ears tired after listening for a long time.
