Good sound when watching a movie is important no less than image quality. When choosing, it will be nice to know how acoustics are divided for a home theater. It happens with several bands, depending on the sound reproduction. The maximum number of lanes is seven. The difference is in the installation method (placement on the floor or on the ceiling) and in the speakers. Acoustics can also be open or closed. Installation of these types is equally easy.
System differences
Home theater speakers have several configuration types. It is possible to carry out installation in the shelf and walls or to place the speakers evenly throughout the room with or without wires.
Built-in acoustics saves space. You can select an open or closed view. The acoustic system of the first type, as a rule, consists of a frame, speaker, protection grill and mounts. With a false ceiling, installation will be difficult due to the additional installation of insulating material.
Closed systems deliver a cleaner, more even sound. Modern speakers look like lamps on the ceiling, so they look good in the interior. Full sound is due to the uniform distribution of the center and front channels.
The standard 5.1 home theater speakers are speakers that are evenly distributed throughout the room, at equal distances. The disadvantage of such a system can be considered wires, of which a large number. They will need to either hide under the baseboard, or purchase additional boxes. To properly configure such acoustics, specialist assistance is required. But if we are talking about a simple layman who does not distinguish between subtleties of sounding, the standard settings of the manufacturer are quite suitable.
Wireless home theater speakers are the most advanced solution. It will be appropriate where there is no way to hide the cable or if there is no false ceiling. Such a pleasure would be expensive. There is an innovation in such a system - satellites, they are located from the rear, and only wires approach them.
pros
Built-in acoustics for home theater has the advantages of:
- Small size.
- An opportunity to enter into any interior, having picked up lattices under color.
- Save space.
- Simple installation.
- In the walls you can install a central and two front channels.
Subwoofer
Acoustic kit 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. This can only be learned empirically.
The universal 5.1 speaker system consists of four front speakers and one central speaker. It also includes a subwoofer. Such a kit is a box type. If the kit includes an additional subwoofer, the system rises to 5.2. There is no limit to the modern improvement of sound, so the acoustics are increasingly being improved in the classroom. Already there are versions up to 9.2. And this is not the limit.
If you want to save money, home theater acoustics may not be a ready-made boxed option, but an individual system. To do this, you need to independently select the individual components.
Power
When choosing good acoustics for a home theater, you need to pay attention not only to its sound, but also to its power. The sound volume will depend on these parameters . Power should be selected not only on their own, but also take into account the size of the room for installing the system. For a large room, it is better not to pick up a small power, you can be disappointed in the choice.
This parameter can be calculated by yourself. This is approximately 10 watts per 1 square meter of area. All brands have a rated power, which in practice is slightly less than the set 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 small power. Enough 100 watts per room.
Selection tips
Choosing the acoustics for a home theater on their own, many mistakenly believe that all components must have the same manufacturer. Professionals will not agree with this. Each company specializes in a specific development vector and in a specific field. Only the competent specialist who understands the intricacies of production can choose the best and the right component. At the same time, combinations for an unknowing consumer may be unexpected.
Important is the body material. Here, preference is given to wood. Cheap body materials do not have the best effect on sound. Special attention should be paid to cables. You do not need to save on them if you want to enjoy a really good sound.
Not the last factor when choosing a system is its aesthetic side. The built-in acoustics for a home theater should appeal to its owner in terms of color and design. Speakers should please no less than the sound itself or a great picture.
Column Design
A diffuser helps to convert an electrical signal into sound by means of air vibrations. In dynamics, this oscillation propagates both directly to the listener, and in the opposite direction. Acoustic kit for home theater includes speakers that can be divided into several types of design:
- The usual and common speaker design is a tightly closed box with a hole for direct sound emission. In this case, the diffuser, making the reverse movement of sound, increases the resonant frequency. The output power of sound waves is reduced. Therefore, this design is typical for inexpensive and simple acoustic designs.
- The phase inverter speaker has a speaker device with sound output from the outside of the speaker. To do this, a rigid tube is installed in the housing, which is tuned to the resonant frequency of the head.
- The column with the labyrinth differs from the bass-reflex in the presence of partitions in the housing. They form a channel for sound from the back of the diffuser. The length of the maze is half the sound wave of the lowest frequency. The phases of the back and front under this condition should coincide.
The last two types improve the low-frequency range of sound. It is simpler to execute and cheaper to manufacture bass reflex subwoofers. Therefore, they are so common.
Stationary
Built-in acoustics for a home cinema should have the correct location in the space of the room for better sound reproduction. Front speakers are placed at an equal distance from each other and from the listener. The gap between the wall and the front element must be at least half a meter. The distance between the columns themselves is at least two meters. System 5.1 should create a rectangle in the center of which the listener is located. Acoustics of type 7.1 should be located similarly to 5.1. At the same time, additional dynamics should be strengthened at the level with the listener.
Home cinema room
Air transmits sound vibrations, they are reflected by the borders of the room and partially absorbed by them. Low-frequency sound and vibration occur not only in the viewing room, but also behind it. If the walls reflect sound well, then its quality is lost. Also, they do not contribute to the good acoustics of partitions with poor insulation.
The best option would be walls that absorb vibration. For their device, you can use mineral wool plates. The worst acoustic option is a room with a reinforced concrete structure and in the form of a cube. In such a space, sound waves, reflected, converge at one point - in the middle of the room.
Active Home Theater Acoustics
The difference between passive and active systems is the presence of an amplifier. In the active, each of the speakers can be adjusted separately. At the input of the amplifiers are active separation filters.
Benefits:
- a wide range of frequencies;
- better sound quality due to the direct connection of the speakers to the amplifier;
- each speaker has its own volume control;
- convenient filtering.
Active acoustics for a home theater has only one significant drawback - the need to connect wires to each speaker.
