Horn speaker frequency divider

　　The loudspeaker frequency divider is a combined filter, which can divide the sound signal into several frequency bands. For example, the two frequency divider is composed of a high pass filter and a low pass filter, while the three frequency divider adds a band-pass filter. The frequency divider is the "brain" of the speaker, which is crucial to the sound quality.

　　Audio technology frequency divider is a kind of audio equipment which can divide sound signal into several frequency bands. As we know, the frequency range of sound is between 20Hz and 20kHz. It is difficult to ensure that a wide frequency sound such as 20Hz and 20kHz can be transmitted with only one loudspeaker, because there will be various problems and difficulties in technology. Therefore, in general, high-quality playback systems, in order to ensure the frequency response and frequency band width of the reproduced sound, mostly use high and low pitch separated speakers for playback in the professional category. When using high and low pitch separated speakers for sound playback, frequency dividers must be used.
