Passive and active speakers for your computer

In any computer system, audio provides an audio card, however, speakers are required to output it. From standard speakers for music centers and speakers, computer speakers differ only in support Audio card. There are two types of external speakers: passive and active speakers. As a rule, they are not intended for high-quality reproduction. Typically, the columns transmit the sounds of video games, creating an appropriate game atmosphere.

Worst of all, passive speakers sound. They are not equipped with an amplifier, and a standard audio card amplifier is suitable only for headphones. The only advantage of such speakers is their extremely low price. They will suit those who do not care about the quality of sound, although it is difficult to find them.

Active speakers for the computer, on the other hand, are equipped with their own amplifier. It enhances and improves the sound of the audio card. Such dynamics are bought, as a rule, in pairs, and on one there must be a regulator of sound. On the columns is more expensive not only a wheel, but also a button that turns off the sound, and sometimes an audio connector, to which you can connect headphones. Of course, the sound level Can be adjusted directly from Windows, but the system controller is not always convenient and accessible. In addition, it provides only 80% of the maximum power of the audio card.

Choosing the active speakers is more convenient for the manufacturer. Acoustics, referring to a well-known brand, will certainly be assembled according to standards. True, sometimes columns are produced by companies that do not specialize in acoustic devices. Such devices may be of poor quality, despite the known name, so it is not worthwhile to completely rely on the brand.

Some active speakers are equipped with a phase-inverter. This device improves the quality of low sounds. Outwardly it resembles a hole in the case of the device, located next to the speaker. In columns of small volume, the phase inverter is useless. It operates only in acoustic devices, the volume of which exceeds one liter.

Having found out the differences between passive and active acoustics, you can choose. First, decide what you need active speakers for. An acoustic device connected to a Standard integrated audio card, will not provide an ideal sound, no matter how expensive it may be. If you need speakers only in order not to miss a call in ICQ, you can do with cheap devices in plastic cases.

Absolutely other active speakers are needed by enthusiastic movie fans or professional gamers. Those who need the effect of a movie theater or need to hear the weakest sounds of computer games, suitable special audio systems, which consist of a subwoofer and satellites. A satellite is a low-pitched column designed to reproduce sounds at high and medium frequencies. A subwoofer is also a column. It is much more massive than the satellite and is responsible for the quality of low sound waves. Stereo sound is perfectly transmitted by satellites of the "2.1" type, and multichannel sound is provided by the "5.1" type.

Now it remains to buy the necessary satellites and a subwoofer, properly arrange them and enjoy the excellent sound of your favorite movie or game.
