Active speakers are also called "active speakers". Usually refers to speakers with power amplifiers, such as monitor speakers, multimedia speakers, active subwoofers, and some new home theater active speakers. Because the active speaker has a built-in power amplifier circuit, users do not need to consider the problem of matching with the amplifier, and it is also convenient to directly drive with a lower level audio signal.
Active speakers refer to a type of speakers with self-equipped power amplifiers inside the speakers. These power amplifiers are specially used to drive the speakers in the speakers. Due to the special matching design, these power amplifiers can be better used to drive the speakers in the speakers, so that users do not need to consider how much power the power amplifier is. And whether the impedance matches and other issues. In addition, because the speaker is also equipped with an electronic frequency divider that divides the frequency in front of the amplifier and each amplifier is only responsible for amplifying the audio signal of a certain frequency, the efficiency of the amplifier can often be made higher, and the distortion is relatively good. Smaller.
In addition, some professional recording monitor speakers with built-in power amplifier circuits and electronic crossover speakers with built-in electronic crossover circuits and amplifiers can also be classified as active speakers.
Passive speakers are also called "passive speakers". Passive speakers are ordinary speakers that we usually use without power amplifier circuit 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. Active subwoofers are also marked with input signal frequency characteristics (such as full-band signal or low-frequency signal), low-pass filter characteristics and other parameters. Passive speakers are generally marked with parameters such as impedance, power, and frequency range.
