For non-professional home theater users, it is not easy to build a home theater system. Therefore, I will share some of the skills with you on how to identify the quality of home theater audio, hoping to help you. !

When choosing home theater audio, the first thing to consider is the sound quality, that is, whether the home theater audio you choose has excellent timbre, an unimaginable degree of restoration, and intonation effect; followed by balance, density, speed, analysis Power and other issues are again based on the size of the audio-visual room. Do not choose too large speakers for small spaces, and do not choose smaller speakers for large spaces. Try to avoid economic waste and lack of performance.

In addition to these, the appearance of the speaker and the overall matching of the living room environment should also be considered when choosing. Building a home theater should be reasonably configured according to the unified hobbies of family members (watching movies, listening to music, singing), room size, and economic conditions. No matter which home theater system you choose, be sure to listen to several representative sound test discs to test whether the speaker system you choose meets the standards.

1. Tonal balance A set of excellent audio equipment will never perform too much additional modification and rendering on the sound, that is, it should faithfully restore the original sound recorded by the sound engineer. A good sound should have a good tonal balance - neither exaggerated nor depressed, you can test the sound with some album or movie clips and pay attention to its tonal balance.

2. A sound with good full-frequency sound effect should be able to cover all or most of the sound frequencies, and even the most extreme sound frequencies can be undistorted. In order to test the bass effect of the sound, try playing some bass drums, brass wind instruments or string pieces to see if the sound is clear and powerful, and at the same time carefully listen to whether the sound of those bass instruments is clear and identifiable; to test the sound of the sound For high-frequency performance, it is necessary to play some clips of violins, piccolos and percussion instruments with high-frequency sounds. Listen carefully to see if the sound quality is clear and smooth when playing high-frequency sounds, and pay special attention to high-frequency harmonics and overtones.

3. Clear, transparent and detailed performance Another criterion for distinguishing whether the sound is excellent is whether the momentary details (such as the sound of "bang" when the big clock is struck) and texture (such as angular plastic limbs or metal pieces are toggled) Guitar strings, when the speaker restores these sounds, can they distinguish their differences) perfectly presented. Test the speakers with a large number of music albums and movie clips with great sound. Listen carefully to the speaker's performance when playing small, faint, and detailed sounds, but during the test, you need to pay attention to whether the speaker starts to emit some unnatural whistling and harsh sounds (this proves that after a long period of time) After the test, the sound has reached its limit and the test needs to be stopped).
