What are the advantages of active speakers and passive speakers in the audio system?

　　Maybe when everyone buys a speaker, the first thing to consider is a "passive" speaker, because it has a player, an Amp, and a complete system. However, for friends who are new to the audio system and start playing from "zero", in fact, "active" speakers have their advantages. Although "passive" speakers are the mainstream, "active" speakers also have many die-hard fans. What is the reason? If the differences in materials and designs of high- and low-end equipment are excluded, only "active" and "active" speakers What are the advantages and disadvantages of passive" design? The following is a brief analysis with you.

　　active speaker speakers

　　The "active" speaker (Active Speaker) means that the speaker has a built-in sound divider and amplifier circuit. It only needs to connect the power supply and input the music signal to make a sound. Many studio listening speakers and engineering professional speakers are active speakers, but don't think that Active Speaker is synonymous with your profession, because common and commonly used computer speakers, Bluetooth speakers, etc. are actually "yes". source" speakers.

　　advantage

　　No need for rear stage, simple system: One of the significant advantages of active speaker speakers is that there is no need to connect a rear stage driver, and you can play songs by inputting audio. It is very suitable for friends who want a simpler sound system. Speakers” can already form a complete system. Space saving: The active speaker speakers do not need to be connected to an amplifier, so a lot of space for placing equipment can be saved. It is quite suitable for the CAS system or desktop audio system that has been very popular in recent years.

　　Complete package, sound quality is "guaranteed": Since the speaker itself already has a complete drive circuit and is equipped with decoding, sound division, and if it is input through a digital interface, the sound bottom of the active speaker speaker will be more "stable", not like no sound. Source speakers are more affected by cables and amplifiers.

　　shortcoming

　　Speakers need to adjust the volume independently: Some active speaker speakers are designed so that the output of the left and right channel speakers needs to be adjusted independently, so it will be a little troublesome to adjust the volume, and the left and right speakers must be matched and then fine-tuned. Need to connect the power cable and signal cable: Although the active speaker speaker has one less Amp, but in addition to the signal cable, each speaker needs to be connected to an additional power cable for power supply, if the speakers are placed far away , the line will be more troublesome.

　　passive speaker speaker

　　The more common two-channel speakers are "passive" speakers. Contrary to "active" speakers, there is no built-in amplifier circuit, and it needs to rely on the output of the rear stage or the combined machine to drive the sound. Compared with traditional active speaker speakers, most of them are bookshelf-type design, passive speaker speakers come in a variety of styles, such as floor, bookshelf, satellite and so on.

　　advantage

　　More flexibility in sound adjustment: Since it needs to be connected to an amplifier driver, the sound bottom of passive speaker speakers will be greatly affected by the connected equipment and the same wire material. Hearing it in my own place, it feels completely different. However, in disguise, there is more flexibility in sound tuning. You can use the characteristics of signal lines and amplifiers to complement or improve the performance of speakers. Only need to connect the speaker cable: Although the amplifier needs to be connected, on the contrary, the passive speaker speaker does not need to connect an additional power cable. It only needs to connect the signal cable to the amplifier, and the latter can be directly driven to produce sound. Diverse connection combinations of Bi-Amp and Bi-Wire: Some passive speaker speakers can support Bi-Amp and Bi-Wire connection methods, and improve the performance of speakers through wire connection, additional power stage, etc.

　　shortcoming

　　Requires post-promotion: Because passive speakers are too diverse, with different specifications, designs and materials, if we want to talk about a common shortcoming, it is the need to connect amplifier drivers, which requires additional equipment and space.
