The core difference between active speakers and passive speakers
Crossover in speakers
A circuit device in the speaker is used to separate the input music signal into different parts such as treble, midrange and bass, and then send them to the corresponding high, medium and bass speaker units for playback.
There are two types:
(1) Power divider, which is located after the power amplifier, and the Lc filter network is set in the speaker to divide the power audio signal output by the power amplifier into bass, midrange and treble, which are sent to their respective speakers. The method is called passive crossover, which is simple to connect and easy to use, but has a large signal loss.
(2) Electronic frequency divider, a device that divides the frequency of weak audio signals. It is located in front of the power amplifier. After frequency division, the bass, midrange and treble signals are sent to their respective power amplifiers, and then the power amplifiers are sent to the bass and midrange respectively. , Tweeter, this method is called active frequency division, the reproduction quality is better, the signal loss is small, but a frequency divider is required.
