Home acoustics: description, types, features of choice

The home speaker system helps you create a true home theater experience, even if your movie screen is not very large. Let's take a closer look at the description, types, and features of the choice of acoustics for the home.

A modern computer or laptop can be connected to a speaker system and enjoy high-quality surround sound, especially during a computer game. Although the TV has its own sound reproduction system, but with separately connected acoustics produces amazingly clear sound... The result is a cinema effect, since the listener is affected by a sound wave from all sides.

The instruction, as a rule, helps with this, but sometimes you need to adjust it yourself if the sound quality does not suit you (for example, you hear an echo or the sound is not clear enough). A standard acoustics system consists of a combination of five satellite speakers and one subwoofer. If you put together such equipment, the system will be called 5.1.

Acoustic systems are divided into 2 categories: active and passive... The main difference between the first version and the second is that the power amplifier is built right into the case.

As stated above, all work is built on the amplifier unit, which is built into the speaker case... The operation of this setting (it adjusts the sound vibrations passing from the apparatus for playback to the satellites) can be easily controlled by turning the knob on the loudspeaker. In addition, the amplifier can reduce the load on the speakers, which significantly reduces the power of the UMZCH. Since the amplifying component is directly connected to the audio speakers, the audio system will deliver enhanced sound quality and clarity. Parts of such a system are less susceptible to heating, which means they last longer.

Musical equipment of modern production has embedded processor... This greatly simplifies the process of setting up home speakers, in contrast to earlier releases of acoustic / music systems, which had a large number of toggle switches. Such an audio system could only be operated by a user with the necessary technical skills.

The disadvantages of an active audio system are as follows:

• it is imperative to use two wires responsible for the signal and power;
• if the amplifier unit is damaged beyond repair, the speaker will also stop functioning properly.

In this version of the audio system no built-in modules - these are ordinary speakers... It is required to select a separate amplifying component. An important point in the selection: the power of the speaker must match the power of the amplifier unit. If the power amplifier exceeds the capacity of the system, the speakers will be damaged. Interestingly, the same speakers sound differently. This difference depends on the connected amplifier.

In the professional field, it is used precisely passive view of audio systems... The main advantage of passive speakers is the ability to be installed at a considerable distance from the stage, closer to the audience / listeners.At the same time, the amplifier (a tool for tuning and control) is out of the reach of the public. Its work does not depend on weather conditions, and it is also protected from damage by intruders. Due to the high power, the electronic components get very hot and may stop functioning - this is a minus of passive systems.

During production, a certain set of high-quality technical characteristics... It is imperative that when buying, the size of the area of ​​the space in which the speaker system will be mounted is taken into account, you need to correctly install and choose the number of speakers. The modern user choice is multichannel surround speakers. Common options are 5.1 or 7.1 systems, but there are 3.1 and 2.1 variations.

It is worth taking a closer look at the main types of acoustics by arrangement.

This type of acoustics can be purchased for an apartment with an area of ​​over 18 m². Most often, a floor system is installed in a spacious living room or in a room with free space, since they themselves columns are massive and voluminous... Floorstanding speakers are under heavy load, so they need a high-quality amplifier. The speaker system must be compatible with your amplifier or AV receiver. When buying, be sure to consult about the value of the recommended power. If incompatible, the receiver or amplifier will not be able to produce clear sound or will turn off altogether if the volume is increased significantly. The "power" parameter is indicated on the speaker system, according to its value you need to choose an amplifier, although some owners compare similar speakers in terms of volume.

If the choice is on floor-standing acoustics, consisting of one device, it is better to choose three-way system. In it, one speaker reproduces high frequencies, the second - the middle and the third - the lower. Good detail is also possible with 2.5 and 3.5 audio systems. The three-way system delivers detailed and rich sound. The number of speakers sometimes does not coincide with the number of bands, since in some audio systems the manufacturer can install 2 bands in one speaker.

This is another type of floorstanding speaker as it sits on the floor. This audio system can be installed in an apartment with a large hall and in spacious rooms with a minimum of furniture. Speakers are mounted on standswhich raise the system 25–40 cm above the floor. With the help of a regulator on the stand itself, you can control the lifting height. The design of the lifts allows you to adjust the clarity of the sound by changing the height level. Some models have recommendations for installing the speakers at the correct height. Without the use of a stand, lowered to the floor, the system produces distorted sound and reduces bass.

Many urban buyers opt for a ceiling speaker system as it suitable for installation in a small room or room up to 25 m²... Another advantage of the ceiling option is absolute independence from space - it does not require a separate space on the floor or wall. An easy-to-integrate system does not require a separate space. Such speakers interface well with two-channel music systems, as well as front satellites for multi-channel audio equipment.

it acoustic set with built-in decoder... Usually the set consists of several speakers, most often two. The small size of the system allows the speakers to be positioned directly on the work desk or on a shelf.There are also more numerous configurations - 5.1 or 7.1 systems. If you do not purchase a subwoofer for this system, the satellites will not give out volumetric bass. These speakers are good for listening to music or watching a movie on your home PC. Satellites are a budget speaker option. It is suitable for those who do not have high sound requirements and do not need a powerful audio system.

This is a new type of music-reproducing equipment that has appeared not so long ago. Thoughtful design will emphasize minimalism and fit perfectly into a modern interior. A soundbar is a compact soundbar with a multichannel (sometimes stereo) system. A noteworthy feature of such audio speakers is the combination of all elements (speakers, amplifier unit, memory card reader).

Although the soundbar has a minimalist look, its musical output equates to full-fledged 7.1 or 5.1 multi-channel sound. A significant disadvantage of the soundbar is not very high power (which means it does not consume a lot of power) and a rather high price category. Soundbars are well suited for small apartments in which music will be listened to at volume. Soundbars support the ability to connect to TV sockets.

Having decided on the type of speaker system, it is recommended that you familiarize yourself with the leading manufacturers of music audio systems before buying.

These are products made in China. This brand was known as SVEN in Ukraine until November 2004... Then the manufacturer stopped cooperation and established direct access to the consumer. F&D independently presented their own products and new lines of related products and equipment. The company is constantly improving its products. The most famous products: active acoustics for home theaters, personal computers. Portable multimedia kits are also available.

The creators of F&D (Fenda) take into account the purchasing power of customers, while not depriving their products of quality. Particular attention is paid to design solutions and ease of use. The company has established itself as a manufacturer of low-cost speaker systems. Most often, consumers who choose 2.1 format acoustics tend to the F&D brand (Fenda). Despite the fact that this is a Chinese manufacturer, the assembly differs in quality and materials used. The sound should be said separately, because clear sound is another plus in favor of F&D.

It is a trade name for a Taiwanese manufacturer that develops and manufactures peripheral computer equipment. Under the Genius brand of KYE Corporation, not only computer components are sold, but also speaker systems for personal computers. For more than 30 years, Genius has a strong presence in the market and has produced inexpensive compact audio systems, as well as technical solutions to improve sound quality. Her speaker systems are compatible with personal computers, netbooks, TVs... Genius's design approach surprises and delights. The basis is a wooden canvas. The use of such material will extend the life of the device and, most importantly, will not distort the sound while playing music.

This is an international company, obtained by combining two manufacturers: International Microlab (America) and Shenzhen Microlab Technology (China)... The task of the new manufacturer is to create not only computer peripherals, but also modern audio systems. A tremendous work has been done to develop, research and introduce new technologies in the creation of acoustic systems for mass use.Very often consumers, seeing the Microlab brand, choose this brand, as they are confident in the sound quality and in the equipment itself.

The company produces more than just compact audio systems. A new generation of Microlab Electronics products - 5.1 devices designed to work together with a TV. With such a system, it is easy to achieve a cinema effect. Lovers of watching movies at home will definitely appreciate the high-quality sound from Microlab speakers. Thanks to the use of a wooden base there are no interference and interruptions in the operation of other equipment in the immediate vicinity... According to a survey of most users, these speakers are the loudest.

It is a Dutch multinational company that has gone from a carbon light bulb to modern diagnostic medical equipment. The range of products is very wide, and the brand is so recognizable that anyone will confirm the quality of Philips products. Portable speakers are popular now, Philips keeps up with fashion. Philips portable speaker system looks modern and impressive, and does an excellent job of reproducing music without generating interference or noise. The body is made using a new technology - with protection from moisture and dust. The wireless speaker option charges quickly. Your Philips speaker system can be tailored to your smart home.

Products from this manufacturer - modern standard of quality for those who prefer to completely immerse themselves in all musical shades. Country of origin - Japan. It is worth noting a wide range of products, among which audio systems and individual built-in components for music reproduction stand out. Russian professional acoustics (guitar and microphones) are highly appreciated in our country and abroad.

To find the right audio system model, you need to study the description of the characteristics. The component part of the speaker system can be of several options.

• 1.0 - designation of portable speakers. On inexpensive models, the sound quality is not very good, but they have the advantage of being small (does not take up much space in a backpack) and you can always take them with you. Portable models are popular among teenagers and young people, and they are also suitable for those who do not want to part with music. More expensive options will have an order of magnitude higher sound quality, but they still do not compare with a real speaker system.
• 2.0 - designation of two front speakers that reproduce sound well in stereo. They are perfect for a desktop and for connecting to a personal computer. With them, you can watch a movie on your home PC or listen to your favorite playlist.
• 2.1 - designation of two front speakers and a subwoofer. Such a system is close to the high-quality reproduction of all sound effects, you can choose it at home. Bass is sent to the subwoofer and other frequencies to the satellites. By installing the amplifier on the floor and placing the satellites at different ends of the table, turning them away from the monitor, you can enjoy watching a movie at home and experience pleasant emotions. For those who really distinguish just good sound from good sound, this option is not suitable, since the subwoofer drops low frequencies, which causes the sound to be distorted.
• 4.0 - designation of two rear and two front speakers. This system provides clearer stereo sound. The 2 by 2 combination is specially designed for inexperienced moviegoers who want to watch films at home. And also they are suitable for personal listening to musical compositions at low volume.
• 4.1 - designation of two rear and two front speakers, supplemented by one more speaker with a subwoofer unit. This is an augmented system (with an amplifier) ​​that produces sound that is close to near-perfect sound. It is perfect for a spacious studio.
• 5.1 - designation of two front speakers, two rear, center and subwoofer. This combination guarantees complete enjoyment of the musical accompaniment. This option is perfect for connoisseurs of high-quality home cinema or computer games with special sound effects.

Let's take a closer look at what other criteria should be considered when choosing home speakers.

• Power... When choosing a power, you need to give up your desires and evaluate the sound quality in a certain area of ​​the room. It makes no sense to buy an expensive audio system if there is nowhere to install it or it cannot fulfill its functions due to the small space. For a small apartment, 25–40 watts per canal is quite enough. If the area of ​​the rooms is large or if it is your own home, you can try to install 50-70 watts. If the audio system will be used for home parties, it is better to take 60-150 watts, for street format celebrations, choose equipment from 120 watts.

For discos and other events related to the constant playing of music, equipment with high performance and low frequencies is used. Consumers trust models such as Sony Shake-66D or LG CM9540... But do not purchase these models for a closed small room - the sound quality and bass will not be reproduced properly due to the fact that the system is designed for a different space.

• Frequency range... High-quality sound is guaranteed provided that the frequency of the bands approaches the range of frequencies that can be detected by the human ear: from 20 to 20,000 Hz. Professional equipment can give higher readings. With a decrease in frequency, the bass is more noticeable, then in computer games the sound from shooting sounds as realistic as possible. Those who need bass should buy speakers with a frequency of 10 Hz, and those who like watching movies in a relaxed home environment should buy a system with a rate of up to 40,000 Hz.

• Material and equipment... The material used to manufacture the speaker box and amplifier affects the sound quality. If during the manufacturing process the manufacturer saves money and makes the case out of plastic, the consumer will receive rattling and extraneous noises while watching a movie. The wood cabinet system delivers clear surround sound. If accessories are included with the system, check that they are of the same length (eg mounting feet). If the length is different, the crooked system will produce a “curve”, “floating” sound.

If you choose between MDF and chipboard models, it is better to stay on the MDF versionas it is of higher quality and more reliable. Chipboard structures are fragile and do not tolerate high humidity. The plastic case can quickly deform, which means it can produce low-quality sound. The aluminum housing will keep the internal parts from damage for a long time, but it will distort the output of the sound.

• Optical input... Modern models of audio systems are designed with an optical input. This technical solution allows the signal to be transmitted by means of a luminous flux enclosed in the cable structure. The signal is fed from the TV's optical output jack to the receiver's optical input.

• The size. There are three main categories of music centers:
  • micro - with a front panel width up to 18 cm;
  • mini - with a front panel width up to 28 cm;
  • midi - the largest and most powerful, they can include detachable elements.

• Bluetooth speakers... Advanced models of audio systems operate on remote control signals. Modern complexes support wireless Bluetooth 4.2.This advantageous advantage distinguishes such systems from others, since they make it possible to listen to music files located on a smartphone, tablet or laptop without using a connecting wire (from the carrier device to the speakers).
