A home theater includes a whole range of equipment, which consists of a speaker system, a multi-channel amplifier, a
receiver and a video / audio signal source. Typically, the kit does not include a playback device, so a TV or
projector must be purchased separately. Particular attention should be paid to the acoustic system, because it is the sound format that can give the desired depth and liveliness to the sound.

Acoustic system – home theaters 2.1, 5.1, 7.1

The sound format of acoustic systems is divided into three main types, namely: “2.1”, “5.1”, “7.1”. The first digit in the sound system means the number of speakers, and the second number of
subwoofers . A standard home theater speaker system consists of 5 speakers and 1 subwoofer, however, some manufacturers allow you to expand the sound system by purchasing more devices.

Home theater 2.1

As mentioned earlier, this system is equipped with two speakers and one subwoofer. Unlike standard TV sound, the latter is able to provide deep bass sound, and the speakers on the sides will give the sound a stereo effect.

Such a speaker system is considered quite simple, since it does not have surrounding playback devices, but the subwoofer certainly makes the sound more spacious. But it cannot be considered a full-fledged volumetric system.

System 5.1

The 5.1 Home Theater System is a complete speaker system that delivers surround sound and the best possible movie experience. Most home theater products are based on this format, as stated in their product descriptions.

This format consists of six channels, five speakers responsible for high and medium frequencies, and one subwoofer that is responsible for reproducing bass frequencies. There are three speakers at the front, one center and two side speakers, and two more rear speakers at the back of the room to provide surround sound. More details can be found in the diagram below.

However, if the room is large enough, then it makes sense to experiment with the location in order to achieve the most acceptable result. It is worth noting that this audio format can be used for playback from most sources. For example, modern video players and digital television support surround sound, even desktop computer sound cards are mostly compatible with it. Home theater setup 5.1: https://youtu.be/66I0IvlsZaE

Home theater system 7.1

This system differs from 5.1 format by the presence of two additional speakers, which are located between the front and rear. This eight-channel version is less popular than its predecessor, but such home theaters can be found on sale. The main advantage of this configuration is even more surround sound, as the additional two speakers form a complete circle. They are designed to create atmosphere, and usually do not reproduce the main sound.

Buying a home theater is primarily a desire to immerse yourself in the thick of the events taking place on the screen. To do this, you need to choose the right speaker system, which will not only be able to accompany the picture on the screen with sound effects, but also provide decent quality. General recommendations for choosing home theaters:

  1. Power is an important indicator of home theater. Of course, it is unlikely that you will be able to listen to powerful acoustics at full volume in the rooms, but the power will allow you to avoid sound distortion, so in this case, the more powerful the better.
  2. The material from which the home theater is made affects not only the external component, but also the sound quality. The case must be strong enough, so it is worth considering wood, plastic or metal as a material.How to choose a home theater 2.1, 5.1, 7.1 and connect
  3. Depending on the room , you should correctly consider the design of the speakers. They are floor, wall and hinged, but a deeper sound is able to give out the floor version. And mounted options can be used in systems where the speakers are also on top.
  4. Frequency range . The human ear perceives sounds in the range of 200-20000 Hz, so you should choose a speaker system that is capable of reproducing sounds in this interval.
  5. The sensitivity parameter is responsible for the volume of the speakers, which is equal to the strength of the current coming out of the amplifier. Simply put, the higher the sensitivity, the louder the final sound.
  6. Arrangement of the acoustic system . Some home theater systems require a non-standard placement of playback devices, this is due to the features of specific models. This factor should be taken into account, otherwise an unpleasant situation may arise, for example, there will not be enough space in the room, therefore, it will not be possible to fully unlock the potential of the home theater.

Set 2 speakers and 1 subwoofer

The main advantage of this kit is its compactness. Of course, this option cannot be considered full-fledged surround sound, since the speakers are located only in the center, but a powerful amplifier complete with a subwoofer can give a new experience from old movies and listening to music. This option fits perfectly into a small room, and at a price it is much cheaper. It is worth noting that in the future this option can be expanded by purchasing additional equipment, but on condition that the receiver allows you to connect additional speakers.

5 speakers and 1 subwoofer

A full-fledged speaker system, which, when properly placed and connected, is able to completely immerse the viewer in what is happening on the TV screen. Among the shortcomings, one can single out bulky dimensions and prices for good equipment. Of course, you can find a home theater with a 5.1 sound format in moderate dimensions, but this option will seriously affect the sound quality, since the cabinet is an important part of the speakers. Such a system is suitable for spacious rooms where there is room for large speakers. However, the larger the room, the more powerful acoustics will be required, so you should not overdo it with choosing a room.

7 speakers and 1 subwoofer

An advanced version of the previous speaker system, offering even more immersion with additional rear speakers, but requires more space. The system is suitable only for large rooms, since a significant distance between the speakers is required to achieve maximum effect. https://cxcvb.com/texnika/domashnij-kinoteatr/kakoj-vybrat.html Speaker layout 7.1.

How to connect a speaker system

Since there are no special differences in the way of connecting speakers of different sound formats, here is an example based on 5.1 speakers.

Manufacturers mark them with literal expressions, they can be used to determine which one should be on the left and which one on the right.
