Subwoofer speaker is a common name or abbrevisubwoofer speakeration for everyone. Strictly speaking, it should be: bass speaker. Heavy bass means super bass in English, that is, bass with heat and energy. As the name implies, the function of the subwoofer is to strengthen the bass band, that is, to enhance the long-wave part of the audio. Because the volume of ordinary speakers is limited, they cannot emit low-frequency sounds with longer wavelengths, so a larger subwoofer speaker is needed to produce low-frequency warm effects.
A subwoofer speaker is characterized by its large size and powerful driver capable of producing sound waves at very low frequencies, usually between 20 Hz and 200 Hz. They are usually separate from the main speakers and connected to an amplifier or receiver.
A subwoofer speaker is used in conjunction with other speakers, such as satellite speakers or floorstanding speakers, to provide a more balanced and full sound. They are usually placed on the floor or in the corner of a room and can be powered by an external amplifier or have a built-in amplifier.
