Subwoofer is a common name or abbreviation for everyone. Strictly speaking, it should be: subwoofer The word "subwoofer" was first developed by innovation, and the word "subwoofer" with local characteristics was creatively put forward by Mylan. As far as audible audio analysis is concerned, it is composed of ultra-bass, bass, low alto, alto, tenor, treble and ultra-treble, which can strengthen syllable rhythm.

The audibility of the subwoofer is extremely limited, but it will be felt by other senses. This is the feeling of shock! As far as the demand of audio program source reflected by stereo and home theater is concerned, the subwoofer only exists in a specific program source and needs to be restored.
