2. Different application scope: Multi-source audio is mostly used in the field of computer multimedia, and passive speakers are generally used in home theaters, combination speakers and karaoke;
3, the volume is different: multi-source sound is a simple sound system is generally small, passive sound is a formal sound system is generally bulky, occupying space;
4. The function of sound source output power is different: when the sound source output power of passive speakers is high, the sound can be played very loudly, otherwise it will be very small; Active speakers have the function of power amplification. Even if the output power of your audio source is very small, the active speaker will amplify the originally small sound very loudly because of the function of the power amplifier.
5. Different output sound effects: passive speakers have frequency division networks and impedance compensation circuits. With these circuits, the speaker has less internal interference, good anti-interference ability and better sound quality than the active speaker.
