One: look at the shape

There are many famous audio brands in the world with different shapes. How can we distinguish between good and bad? First of all, the fine speakers will handle the details very well, and there will be no burrs, sticky edges and corners. The lacquer surface will also be treated very round, the lacquer surface is smooth as a mirror, and the reflected image is clear and not deformed. Inferior speakers have many problems, and the details are not handled very well. What’s more, more tricks can be seen in the inverted hole.

Two. Tonal balance

A good sound must have a good timbre balance, and it cannot be suppressed or exaggerated. You can use some albums or good movie clips to test the sound, pay attention to its tonal balance.

Three: full frequency sound

A good sound system should be able to cover all or most of the sound frequencies, even extreme sound frequencies can be undistorted. In order to test the bass effect of the sound, try to play some bass drum, brass or string fragments, and listen to whether the sound is clear and powerful, and also carefully listen to whether the sound of those bass instruments is clear and discernible; test the high-frequency performance of the audio , Need to play some high-frequency sounds of violin, piccolo, and percussion instruments. When playing high-frequency sounds, listen carefully to see if the texture is clear and smooth, paying particular attention to high-frequency harmonics and overtones.

Four: bass effect

The bass effect of the speakers can be said to be a very important part of the overall sound quality, which is directly related to the shocking effect of the fullness of the sound effect. For the performance requirements of speakers using woofers, we also conducted the following tests. Put a glass of water on the side of the speaker. A speaker with a good bass effect will cause the cup to vibrate, and the water in the cup will also be rippling. The better the bass effect is, the more obvious the effect and the longer the time.

Five: midrange effect

For most speaker products, it is difficult to distinguish the sound quality of the midrange part. And his main role is to produce a sense of reality, the test of the midrange is to watch multi-channel movies.

Six: Tweeter

Generally speaking, the treble effects of speakers are very intuitive, such as singing and some special electronic sound effects, and even some extreme sounds beyond the listening range.
