The essential difference between active speakers and passive speakers is whether they have a power amplifier. Other differences are:
1. The effect of the output power of the audio source is different: when the output power of the audio source is high, the sound can be played very loudly, otherwise it is very small; the active speaker has the function of power amplification, even if the output power of your audio source is small, it will Because of the power amplification function, the original small sound will be amplified very loudly.
2. The scope of application is different: active speakers are mostly used in computer multimedia fields, and passive speakers are generally used in home theaters, combination speakers, and karaoke;
3. Different sizes: Active speakers are simple audio systems and are generally small, while passive speakers are formal audio systems, which are generally bulkier and take up space;
4. Different output sound effects: Passive speakers have a crossover network and impedance compensation circuit. With these circuits, the speakers have less internal interference, good anti-interference ability, and relatively better sound quality than active ones.
5. There are still many differences between them. Active speakers have built-in power amplifiers, while passives need to be connected to an external power amplifier to work, but passives also have advantages. Passives are smaller in size than actives, which can save space, while actives are heavier. It takes up a lot of space.
6. The output power is different. When the output power of the passive sound source is high, the sound can be played very loudly, and the passive sound quality is relatively better than the active one. The active has the function of power amplification, even if the output power of the sound source is small, It will also amplify the original small sound loudly because of the power amplification function.
