What are active speakers and passive speakers

                              What are active speakers and passive speakers

Active speakers, also known as active speakers, usually refer to speakers with their own electronic crossover system and power amplifier. Active speakers usually only need to be connected to a power supply and a signal source to produce sound without adding an additional amplifier. Most of the current monitor speakers or engineering speakers and speakers used in dance halls are active speakers, and some desktop speakers, Bluetooth speakers and smart speakers are basically active speakers.

The advantage of an active speaker is that it has its own power amplifier, no need to add an additional amplifier, it is easy to use, and easy to use. It can be used by directly connecting the signal source, without entanglement or consideration of power level, impedance matching and other issues. There is also a built-in electronic frequency division system and decoding system, which reduces the connection of wires, can better restore the sound effect, has less distortion, and plays stably without the influence of external factors such as wires and power amplifiers. The disadvantage is that active speakers are generally bookshelf boxes, and most of them can only build 2.0 systems, it is difficult to build multi-channel systems, and the range of use is relatively narrow.

Passive speakers, also known as passive speakers, do not have any internal amplification circuits, but generally have built-in frequency division systems and impedance compensation circuits. It needs to be connected to an additional amplifier before it can be used, but there are relatively more types of speakers than active speakers. In addition to typical bookshelf speakers, there are also floor-standing speakers, satellite speakers, and now more popular custom-installed speakers.

The advantage of passive speakers is that they can be directly connected to the amplifier without an external power supply. The tuning is flexible and can be widely used. You can also adjust the power amplifier and wires to determine the sound effect according to your needs. It has stronger playability and can be used more Good build multi-channel sound system. The disadvantage is that the system of passive speakers is much more complicated than that of active speakers, especially for users who want to play well, they need to have more professional knowledge reserves and better hands-on ability. Or different effects, you need to have more audio-visual knowledge. In addition, the volume of general passive speakers is larger than that of active speakers, so the space required will be relatively larger.

As for how to choose, you can consider the application scenario, the desired effect and the budget. If you only need to use it as a computer speaker, it is of course more suitable to choose an active speaker. If it is a living room or an independent audio-visual room, although active and passive speakers can be selected, in terms of effect, it must be more appropriate to choose passive speakers. Or if you are not afraid of tossing and want to try different sound effects, or need to match with different styles of equipment, then passive speakers are definitely suitable; . From the perspective of budget, if you have money, you are not afraid of tossing, so you still have to choose passive speakers.
