PC Speakers

Manufacturers now offer specialist audio PC speakers that let you convert your PC into a hi-fi. For this, the first requirement is a quality sound card, to connect to PC speakers good.

Moreover, by acquiring PC speakers must consider features such as power, frequency response, impedance, sensitivity, performance, distortion or directionality.

Sound Systems

We can distinguish three sound systems:

Mono system (1.0): recording and sound reproduction takes place through a single channel, so that no spatial feeling. Stereo (System 2.0): the audio is recorded and played on two channels, typically left and right channels, creating a sense of space.

The 2.1 stereo system adds a channel that plays bass in a subwoofer.

Surround uses multiple audio channels to cause a wraparound effect. The terminology comes from the Home Cinema and video games: the first number indicates the number of full-range channels (full-range) and the second the number of channels bass (subwoofer), being the total number of speakers the sum of all channels. For example, a 5.1 system consists of 5 full-range channels and a subwoofer channel, 6 speakers in total PC. There are many provisions, the most extended 5.1 and 7.1 systems.

PC speaker types as the frequency range

There are several types of PC speakers as the frequency range where they provide optimal performance:

Full-range speakers (full-range) are not specific PC speakers with an acceptable frequency response across the range of frequencies. Subwoofer: are speakers designed for lower frequencies (20 to 80 Hz). Woofer: Speakers are designed for low frequency sounds (40 Hz to 1 kHz). Medium: are dedicated PC speakers midrange (800 Hz to 5 kHz). Tweeter: are specialized in high frequency speakers are optimized for high frequencies (4 to 20 kHz).

Types of PC speakers as the number of tracks

According to the PC speaker sound system can be:

One-way speakers: the speaker has only one speaker, usually full-range (full range). Two-way speakers: the speaker has two speakers, a woofer and a tweeter. Three-way speakers: the speaker has three speakers, a woofer, a tweeter and a half.

PC speakers in various ways, the audio signal is divided by active or passive crossovers, sending each given range of frequencies to the appropriate speaker.
