Active Speaker
Also known as "active speaker or powered speaker". Usually refers speakers with power amplifiers, such as active line array speakers, active subwoofer speakers, and some active monitor speakers. Since the active speaker has a built-in power amplifier circuit, the user does not have to consider the problem of matching with the amplifier, and it is also convenient to be directly driven by a lower-level audio signal.
Passive Speaker
Also known as "passive speaker". Passive speakers are ordinary speakers that we usually use without power amplifier circuits inside. Although passive speakers do not have amplifiers, they often have crossover networks and impedance compensation circuits. Active speakers are usually marked with parameters such as the output power, input impedance and input signal level of the built-in amplifier.
