According to the playback rate, it can be divided into full band speakers, bass speakers, and subwoofers.

The so-called full band speaker refers to a sound system that can cover the low frequency, medium frequency, and high frequency range for playback. The lower limit frequency of a full band speaker is generally 30Hz-60Hz, and the upper limit frequency is 15KHz-20KHz. In general small and medium-sized audio systems, only one or two pairs of full frequency speakers can fully fulfill the playback task. Bass and subwoofers are generally specialized speakers used to supplement the low-frequency and ultra-low frequency playback of full band speakers. This type of speaker is generally used in large and medium-sized audio systems to enhance the strength and shock of low-frequency playback. When in use, most of the low-frequency signals are sent to a specialized bass amplifier after being divided by an electronic frequency divider (splitter), which then drives the bass or subwoofer speaker.
