Built-in acoustics for home theater

A good sound when watching a movie is as important as the quality of the image. When you choose, it will be nice to know how the acoustics for the home theater are divided. It happens with several bands, depending on the sound reproduction. The maximum number of bands is seven. The difference exists in the way of installation (placement on the floor or on the ceiling) and in the speakers. Also acoustics is open or closed type. Mounting of these species is equally easy.

Differences in systems

Acoustics for home theater has several types of configuration. You can mount it in a shelf and walls or place the speakers evenly around the room with or without wires.

Built-in acoustics save space. You can select an open or closed view. The first type of acoustic system , as a rule, consists of a frame, a speaker, a protection grid and fixtures. With a false ceiling, installation will be difficult with additional insulating material.

Closed-loop systems transmit a cleaner and more even sound. Modern speakers look like lights on the ceiling, so they look good in the interior. A full sound is due to the uniform distribution of the center and front channels.

The standard 5.1 acoustics for a home theater is a column that spaced evenly around the room at an equal distance. The minus of such a system can be considered wires, which a large number. They will need to either hide under the plinth, or purchase additional boxes. To properly configure such acoustics, you will need the help of a specialist. But if we are talking about a simple inhabitant who does not distinguish between the subtleties of sound, the standard settings of the manufacturer are also quite appropriate.

Wireless home theater speakers are the most modern solution. It will be appropriate where there is no way to hide the cable or there is no false ceiling. Such a pleasure will not be cheap. In such a system there is an innovation - satellites, they are located from the rear, and only wires come to them.

pros

Built-in home theater speakers have advantages:

- Small size.

- The ability to fit into any interior, picking up the grid for color.

- Space saving.

- Easy installation.

- In the walls you can install a central and two front channels.

Subwoofer

A set of acoustics for a home theater must have this element in it. Its location depends only on the desire of the owner. But still you should install it where its sound will be optimal. You can learn this only by experience.

The universal 5.1 speaker system consists of four front speakers and one central speaker. There is also a subwoofer. Such a set is box-type. If the kit includes an additional subwoofer, the system rises to 5.2. Modern sophistication of sound has no limits, therefore acoustics are increasing more and more in the classroom. Already there are versions before 9.2. And this is not the limit.

If you want to save money, home theater acoustics may not be a ready boxed option, but an individual system. To do this, you need to make a choice of individual components.

Power

Choosing a good acoustics for home theater, you need to pay attention not only to its sound, but also to power. The volume of the sound will depend on these parameters . Power should be selected not only at will, but also take into account the size of the room to install the system. To a large room, it is better not to select a small power, you can be disappointed in the choice.

This parameter can be calculated by yourself. This is approximately 10 watts per square meter of space. All trademarks have a nominal power, which in practice is slightly less than the specified, depending on the model. For a small room and a small number of people, the built-in acoustics for a home theater can be of little power. Enough 100 watts per room.

Tips for choosing

Choosing acoustics for a home theater yourself, many mistakenly believe that all components must necessarily have the same manufacturer. Professionals do not agree with this. Each firm specializes in a specific development vector and in a specific field. To pick up the best and right component can only a competent specialist who understands the intricacies of production. At the same time, combinations for an unaware consumer may be unexpected.

Important is the case material. Here the preference is given to a tree. Cheap materials of the case do not have the best effect on the sound. Separate attention should be paid to cables. They do not need to be saved if there is a desire to enjoy a really good sound.

Not the last factor in choosing a system is its aesthetic side. Built-in home theater acoustics should be liked by its owner in terms of color and design. Pleasing speakers should be no less than the sound itself or an excellent picture.

Registration of columns

The diffuser helps to convert an electrical signal into sound with the help of air vibrations. In dynamics, this oscillation spreads directly to the listener, and in the opposite direction. The set of acoustics for a home theater includes columns, which can be divided into several types of design:

- The usual and common design of the speaker is a tightly closed box with a hole for direct sound emission. In this case, the diffuser, making a reverse motion of sound, increases the resonance frequency. The output power of sound waves decreases. Therefore, this design is typical for inexpensive and simple designs of acoustics.

- Bass reflex speaker has a speaker device with the output of sound oscillations from the outside of the speaker. For this purpose, a rigid tube is installed in the body, which is tuned to the resonance frequency of the head.

- A column with a labyrinth differs from a bass reflex by the presence of partitions in the body. They form a channel for sound from the back of the diffuser. The labyrinth along the length is equal to half of the sound wave of the lowest frequency. The phases of the rear and front parts must coincide under this condition.

The latter two types improve the low-frequency range of sound. Simpler in execution and cheaper in cost manufacture of bass reflex subwoofers. Therefore, they are so common.

Stationary

The built-in acoustics for a home theater should have the right location in the room space for better sound reproduction. The front speakers are placed at an equal distance from each other and from the listener. The gap between the wall and the frontal element must be at least half a meter. The distance between the columns is at least two meters. System 5.1 should create a rectangle in the center of which the listener is located. Acoustics type 7.1 should be placed similarly to 5.1. At the same time, additional dynamics should be strengthened at the level with the listener.

Home Theater Room

Air misses sound vibrations, they are reflected by the boundaries of the room and partially absorbed by them. The sound of low frequency and vibration occur not only in the viewing room, but also behind it. If the walls reflect well the sound, then its quality is lost. Also do not contribute to the good acoustics of the partition with poor insulation.

The best option is the walls that absorb vibration. For their device, mineral wool plates can be used. The worst acoustic option is a premise with a reinforced concrete structure and in the form of a cube. In such a space, sound waves reflecting, converge at one point - in the middle of the room.

Active acoustics for home theater

The difference between passive and active systems is the presence of an amplifier. At the active, each of the speakers can be adjusted separately. At the input of the amplifiers there are active separation filters.

Benefits:

- wide frequency range ;

- Better sound quality due to direct connection of speakers to the amplifier;

- each column has its own volume control;

- convenient filtration.

Active acoustics for home theater has only one significant drawback - the need to connect wires to each speaker.
