Embedded Speakers for Home Cinema

At choosing acoustics for home theater Pay attention to the embedded options. Such systems provide an opportunity for imperceptible fusion of acoustic technology with the interior, taking into account all its design features. Truly the perfect sound of a home cinema is provided by speakers mounted in the ceiling, and at the same time they are completely invisible. Built-in and ceiling acoustics make the sound range close to perfection, fully realizing the effect of presence.

Benefits of built-in acoustics

Far from all apartment owners, especially small-sized ones, succeed quite effectively. place the components of your home theater. Creative solution in cramped housing conditions was helped by the creators of modern acoustic systems. The built-in acoustics complex not only helps to maximize the use of the interior, but also greatly facilitates the financial burden.

Modern advances in the design of embedded speakers, dynamic tuning of interior resonators, system fusion - all these factors contribute to home theater sound level at least not lower than the case speakers. Of course, if we are talking about right accommodation and installation of embedded equipment.

The cornerstone of embedded home theater acoustics is the rational and intelligent placement of speakers in wall or ceiling openings. Acoustics of this type should not only harmoniously fit into the interior, but also be compatible in terms of technical functions with its size and features. The most important advantages of built-in acoustics are:

1. Constructive details that create ideal conditions for the sound of the speakers. For example, special rubberized damperwhich absorb intrusive rattle and make the sound system juicy and expressive.
2. Conditions for more accurate column placement. Having predetermined the position for them, you can achieve perfect surround sound.
3. Ability to create homogeneous sound level throughout the home theater.
4. Aesthetics registration of the room. By hiding the speakers, you can plan a more expressive and harmonious interior without spending space on the placement of outdoor speakers.

Embedded speakers provide a free planning home theater. This quality strikingly distinguishes them from the rigid placement of outdoor speakers.

Of course, installing built-in acoustics is not easy, but the costs are completely paid off by getting the most natural sound. The built-in acoustics, recessed into the walls, is completely invisible and reveals itself only by sound. For labor it is necessary to include equipment in the walls of proper openings and work on sound insulation of walls.

Installation Features

When creating a home theater system, it is important to decide when the built-in speakers will be mounted: in the finished room or at the construction stage? When placed during construction, preference is given to columns with own body. They are much easier to mount, as a result, you can realize maximum power with high-quality clear sound.

Built-in acoustics, designed for placement in the wall, reaches a considerable size. This improves the performance factor, especially in the low-frequency spectrum. In addition, the sound of such systems will not resonate in adjacent rooms. If used acoustic box, then the influence of extraneous electromagnetic field is excluded, plus a high degree of fire safety.

The volume of metal needed to eliminate disastrous vibrations is called an acoustic box. This ideal speaker placement system is installed close to the guides, not to a drywall sheet. Most of these volumes are fire resistant.

There are systems where the built-in speakers are located in acoustic boxes on swivel mount, which makes it possible to adjust the direction of the audio stream. The disadvantage of this arrangement is the high cost.

Nuance: with the floor configuration, the components of the speaker system can be purchased randomly, from different manufacturers.Built-in acoustics, as a rule, is implemented in ready-made kits, different in design features and power.

Any embedded system has protective grid from metal. As a rule, a trap is provided with the grate to protect against dust. It is possible to paint the outer flange of the grid in any color, according to the color solution of the interior. Home cinema with built-in acoustics, of course, looks more solid compared to the wired version.

Installing an embedded system

The generally accepted method of mounting built-in speakers is the following:

1. A drywall sheet is hardened between the outer flange and the inner paws.
2. Columns are placed through the cut, made on special patterns, usually included in the kit.
3. Then a protective grid is installed on the outer panel.

There is a panel that makes the speakers relatively invisible. It is mounted to the wall or ceiling level and plastered to match the wall plane.

For the installation of the components of the built-in speaker system, you must use a special installation cablecorresponding to the rules and standards of fire safety.Such a cable is assembled from two wires, insulated from each other and placed in a carrying refractory insulator. A special cord is laid in the cable, which gives it additional reliability and helps to pull it through pipes for considerable distances. It is worth noting that embedded systems can be wireless, but it will affect the quality of the sound.

The best accommodation option is 1 column per 20 square meters. m square It is necessary to make a footnote to a number of details, such as the level of the ceiling of the room, the noise factor, decorative details of the room.

Speaker Placement

Optimally, all three front speakers should be in line with the ear of the seated listener and equidistant from each other. This arrangement will allow the audio signal to reach the listener along the shortest path. If, due to interior features, equidistance is not observed, it is necessary to balance it. scheme receiver or processor.

Both side channels optimally should be placed slightly above the level of the ear and moved back from the perception zone.

The simplest option is embedded subwoofer for home theater - it's elementary subwoofer. Mounted such a column as well as ordinary embedded. A high-end sub is a woofer in an acoustic volume. Such a combination is usually placed in the wall. The most effective is the use two subwoofers. This scheme ensures a uniform distribution of bass over the entire area of ​​the sound, while the output sound signal increases decently.

The exact location of both subwoofers is extremely important and the best option is their symmetrical placement relative to the listening area. Thus, the correct acoustic summation, without cases of the prevalence of one frequency or the disappearance of another.

Built-in subwoofer is a passive speaker, for its operation requires a specialized power amplifier.

With all the simplicity of the issue with the power amplifier, it is necessary to clearly understand that there is no simple linear amplifier that would provide the necessary power for three or more pairs of speakers built into the wall. To ensure a decent level of sound using specialized multichannel amplifiers. Only in a very small room is it possible to use a home amplifier with two pairs of speakers.

Ceiling acoustics

Strictly speaking, all built-in acoustics can be divided into two segments:

• acoustics ceiling;
• acoustics embedded in the wall.

Initially, the scope of application of ceiling acoustics were production facilities: cafes, subways, shops. In connection with the rapid development of technology, ceiling speakers are more and more common in everyday life.

Ceiling speakers or surround speakers suggest perfect sound wave propagation. Mounting the speakers in the ceiling, you can achieve the effect of complete invisibility of sound equipment. As a rule, this is the lot of sophisticated music lovers. The main advantages of ceiling speakers:

• small size, "invisibility" in the design, complete protection from external influences;
• ceiling speakers do not overload the space;
• mounting is similar to mounting spotlights.

When installing it is necessary to know the distance between the ceiling and the suspended ceiling, since ceiling acoustics depth of about 15 centimeters. To prevent unnecessary vibrations use special sealing pads. Ceiling acoustics suitable for any performance ceiling: stretch, panel. The columns are so easy to assemble that you do not need to change the structure of the ceiling.

Using such speakers, you can equip with high-quality sound of the room where it is impossible to install floor systems: a kitchen, a bathroom, a room with a pool.

System Setup

First step in home theater setup there is always a test of the built-in columns using tone generator. The next step is to check the polarity using the automatic installation options on the receiver. The use of speakers without a rear case will defocus the sound, and it will be transmitted to adjacent rooms, therefore it is highly desirable to use rear housings. With the exact location of the two subwoofers, the listening area has a good balance and the inevitability of correction disappears.

A good location of the built-in acoustics and its correct setting will give a lot of wonderful moments of high-quality listening to music, and the level will be no worse than the hull systems.
