What does a subwoofer mean?

Subwoofer means subwoofer, which is a loudspeaker device specially used to relax bass.

Generally speaking, we divide audio into subwoofer, bass, alto, alto, tenor, tenor, tenor and so on. Subbass refers to the bass whose lower playing frequency is above 20Hz. When playing back the sound effects of large dynamic music or movies, the subwoofer is more important than the traditional floor stereo speakers, and the sound effects are magnificent and dynamic.

The function of the subwoofer:

The main function of subwoofer is to improve the sound quality, increase the bass texture of sound, and effectively strengthen the effect of syllable rhythm. With it, the restoration of the program source can be more solid. Without it, it gives people the feeling that they are powerless and lack of energy.

For example, in the cinema or in reality, we can feel the shock of the strength and energy when the plane takes off, but if our home theater is not equipped with subwoofer speakers or the configuration is unreasonable, people will not feel this shock, but that's all.
