The wall-mounted method of installing acoustic components is justified in many operational parameters. This is also confirmed in the application of this configuration when providing sound equipment for assembly halls and cinemas. In addition to saving space in the room, wall-mounted acoustics allows you to most profitably perform the main task of reproducing sound waves with the best audibility.
Varieties of systems
The traditional wall-mounted acoustics are monopolar mounted type constructions. These are the speakers that create the sound within the narrow corridor. The range of angular propagation of waves depends on the size of the sector, characterized by the directivity pattern of the speakers. Bipolar wall acoustics provides the widest orientation of the speakers - the working angle is about 180 degrees. Such are often used in cinemas to ensure maximum immersion of the audience in the sound picture.
For TVs, it is advisable to use flat acoustic systems. Developers often produce such devices in the form of panels that organically complement the television segments. Obviously, their sound favorably replaces the regular speakers that make up the basis of TV equipment. Spherical wall acoustics for the house in the form of suspended loudspeakers is also popular. The original form of such devices, on the one hand, contributes to the effective distribution of sound waves, and on the other hand, it can act as a full-fledged object of interior decoration.
Wall Acoustic Performance
When choosing a wall-mounted sound system, you should be guided by the same operational parameters as in the case of other types of acoustics.
The differences mostly relate to structural designs, but they, as a rule, only enhance the basic characteristics. So, first of all, wall-mounted acoustics must meet the requirements for power, which in typical systems varies from 10 to 100 watts. Further, the range of reproducible frequencies is taken into account. The optimum is considered a corridor from 68 to 20 000 Hz. You can also pay attention to impedance and sensitivity, but here the indicators are mostly the same and are respectively 6 Ohms and 85 dB.
Optimum housing material
Usually, the choice is between wood and plastic cases, each of which has its own advantages. More affordable plastic has advantages in the form of a small mass, simplifying installation work. It is beneficial to purchase such models from a design point of view. The design with aesthetic plastic cases is in harmony with almost any environment, if the color scheme is correctly selected. As for mounting, the wall mount is usually used in the form of standard brackets. A lightweight plastic construction is not as demanding on a power supporting base as wooden counterparts, which, however, have many other advantages. The main advantages of cases made of natural material are the ability to accurately and without distortion reproduce the sound picture. Optimum system stiffness minimizes the impact of overtones while maintaining natural reproduction.
Acoustics amplification
To begin with, it should be noted that acoustics can do without additional amplification at all. On the other hand, the inclusion of additional equipment with an amplification effect in the complex will significantly improve the sound characteristics.
Active systems provide for the presence of such additions on each of the bands, while their final separation is performed by the filters at the output. In general, active filters are more effective than passive filters, because they allow you to get high-quality sound control. In passive systems, wall-mounted speakers may also have improved acoustic tuning capabilities, but this will require the connection of an external amplifier. In active systems, a separate power supply is provided for each speaker.
Choosing a Home Theater System
The wall-mounted principle of fixing the speaker system is optimal for organizing a home theater.
If possible, then initially you should focus on the built-in equipment, which will be integrated into the wall. The only drawback of such systems is the use of metal profiles, which can complicate the installation. But if physically there is such a possibility of installation, then the trouble of installation is completely blocked by the achievement of surround and deep sound. Most often, wall-mounted acoustics for a home theater are represented by massive panels, in which the back side is fully adapted to the use of switching means. Such configurations can also cause a lot of problems, especially if you plan to use individual and non-standard connection schemes. As a simplified option, you can offer small mounted speakers, which are easier to install, but the sound palette in such systems is less pronounced.
Installation of wall acoustics
Usually, kits with acoustics include devices for mounting equipment. In standard versions, these are sets with brackets of suitable sizes. Manufacturers try to maintain the functionality of the mounting devices as much as possible, allowing them to perform turns, inclinations and other manipulations with the equipment during operation. The speaker bracket itself is installed through the holes in the wall with screws. The formation of mounting holes should be approached responsibly, since the strength of the structure as a whole depends on the reliability of the integrated hardware. And here we can recall the differences between wooden and plastic systems, the mass of which determines the requirements for the bearing qualities of fixing devices.
The best models of wall acoustics
Among universal systems, Cambridge Audio WS30 speakers can be preferred, the sound capabilities of which correspond to traditional ceiling systems. Users note the confident dynamics of the equipment, and a good disclosure of a wide range of frequencies. Noteworthy is the PMC Wafer 2 system, which used Twin Tweeter technology. In addition to decent playback characteristics, the speakers of this complex are easy to install. Using a standard speaker bracket, the user can hang the speakers horizontally and vertically. From the point of view of playing accuracy and detail processing of sounds, one of the best wall systems is the DALI Ikon 5 Mk2 kit. It is suitable for use as a universal system, and as an addition to a home theater.
Conclusion
Organizing the space for sounding the room, one should take into account not only the characteristics of the sound system. Even before buying it, you need to calculate the area of the room, which in the future will allow you to more accurately determine which wall-mounted acoustics will best cope with specific tasks. In some situations, it is more appropriate to use combined broadband systems, including sets of speakers of different types. In other conditions, massive front speakers complemented by wall-mounted satellites are more likely to do.
