What are the differences between active and passive speakers?

Active and passive speakers refer to whether the speakers have built-in amplifiers.

Active speakers: Active speakers are also called active speakers or automatic gain control (AGC) speakers. They have integrated amplifiers and usually include some tuning functions such as volume control, equalizer, etc. Active speakers are usually suitable for users who do not want to buy additional amplifiers because they can produce sound directly by connecting to the sound source.

Passive speakers: Passive speakers are also called passive speakers. They do not have built-in amplifiers and need to be connected to an external amplifier when used. Passive speakers are just a speaker system that converts input electrical signals into sound output, but cannot directly produce sound.

Main differences: · Connection method: Active speakers can be directly connected to the sound source device (such as mobile phones, computers, CD players, etc.) through cables, while passive speakers need to be connected to an external amplifier to work properly. · Flexibility: Active speakers have built-in amplifiers and tuning functions, so they can be used independently, making them more portable and flexible. Passive speakers, on the other hand, need to be used with an external amplifier, which makes them relatively large and less portable. · Expense: Generally speaking, active speakers are slightly more expensive than passive speakers because they have integrated amplifiers and other functions. When choosing a speaker, you need to decide whether to choose an active or passive speaker based on your personal needs, budget, and usage scenarios.
