Playing music with knowledge without equipment is like "talking on paper". Therefore, it is very important to choose a good set of sound equipment, but now the sound market speaker brand is mixed, how to find a suitable and reasonable price sound equipment in the complex market makes many people confused. The following editor will teach you some good or bad techniques to identify sound equipment.
（1） Natural balance of tone
First of all, the sound reproduction of the speaker should be true. The sound of human voice and instrumental music should be as close as possible to the original sound without too much distortion. The sound you hear should be smooth and silent, without the strongest or weakest sound you can hear. The mid frequency and treble should not be too loud or held back. You can find a wide range of instrumental music (such as piano music) recordings to play. Pay attention to the change of timbre when listening to low, medium and high scales.
（2） Sound characteristics
Although the overall sound performance of speakers is very important, good speakers should also perform well in the following special situations:
Frequency balance: listen to different frequency bands in turn. The bass should be compact, clear, and accurate in tone, without buzzing, muddling or blurring; the midrange, as the main part of music, is more important. The human voice and instrumental sound should be natural, with details, not too loud or dull, nor too bright or too light. The high pitch should be open, with air sense and extensibility, without shrieking or fading.
Analytical: listen carefully to see if you can hear the details of the music, such as the decline of cymbals or pianos, the hall sounds of concert halls or jazz clubs. If the details of low-level can not be heard clearly, it means that the speaker lacks transparency. In order to achieve a real and satisfactory playback effect, the analytical power at low level is very important. This is also the difference between a good speaker and a bad speaker.
Transient response: the speaker should be able to reproduce the transient in music. The sound of just beating a string drum or a strong guitar should be strong and accurate. It should not make people "surprised", "excited" or "slow" or "dull". In addition, natural fading sounds, such as cymbals and the "tailing" of speech, should fade gradually and stop abruptly.
（3） Sound environment of sound box
If you try to listen to the speaker in an improperly positioned sound shop, you are unlikely to hear the full performance of the speaker. Because the positioning of the speaker in the room is very important, even if the speaker is moved forward or backward a few centimeters, the low-frequency response of the speaker will be greatly changed. When the speaker is placed in a room that can enhance or weaken the bass, the balance of the tone will change, or rich bass or no bass will be heard. Moreover, the sound box is not placed at the right time, and it is less than the sound of sound image positioning originally. Therefore, it is necessary to find a proper place for speakers at home, so that speakers can fully display their power and show their skills
（4） Listen to familiar music
Since the recording quality of CD records is very far related, there are many times, so when you go to the audio store to try and buy speakers, you'd better bring more CDs of high quality that you've heard well. In this way, you can hear which ones are on the CD recording and which are held by the speaker.
