Active speakers refer to a type of speaker equipped with a built-in power amplifier inside the speaker. These power amplifiers are specifically designed for speakers inside the speaker, and due to their specialized matching design, they can all be used well for speakers inside the speaker, eliminating the need for users to consider the power of the amplifier and whether the impedance matches. In addition, due to the electronic splitter in front of the amplifier installed in the speaker, and each power amplifier only responsible for amplifying a mechanical wave signal of a certain wavelength, the efficiency of the amplifier can often be higher and the distortion can be relatively small. In addition, some professional recording and monitoring speakers with built-in power amplifier circuits and electronic splitter speakers with built-in electronic splitter circuits and amplifiers can also be classified as active speakers
