What kind of sound system for home theater to choose - 5.1 speakers or 7.1 speakers? - Technology - Electronics

5.1 speakers system is a set of radiators, each of which is assigned the function play a certain part of the sound frequency range. It is capable of converting electrical oscillations into oscillations of air particles. Thanks to this man pick up a different sound. And on the accuracy of conversion depends on the sound quality fluctuations.Currently, there are many varieties of speaker systems. The main categories of speakers: Active Speakers, built-in speakers, Bookshelf speakers, outdoor speakers, satellite speakers, weatherproof speakers, sound projectors and subwoofers.A distinctive feature of the active speaker system is a built-in amplifier power, thanks to which this kind of acoustic systems used primarily in the professional arena. You can use it to get crisp, clear and deep sound.Built-in speakers allow you to not clutter up the room and still play sounds no worse than large speakers. Such equipment can be mounted in a wall or ceiling. In addition, it can be repai nted.All-weather speakers designed for use in the external environment. In this case, adverse and harsh weather conditions are not an obstacle to good sound.Bookshelf speakers are very compact and flat consists of 5-6 small speakers that are installed around the perimeter of the entire room to play the treble, and subwoofer to play low frequencies. Outdoor speakers are overall.Sound Projector can get a great sound with just one column. It has a compact body and independently creates a virtual multi-channel sound. In the case of the traditional sound of the projector you can find lots of small speakers, each of them have its own power.Subwoofer designed to reproduce low frequencies. On the sound track subwoofer spelled bass effects. In addition, it can be both active and passive. Active subwoofer - is a low-frequency speaker system with built-in power amplifier.Home theater usually consists of acoustics center channel, front and rear of acoustics and subwoofer. In 5.1 speaker s system center channel is located on the same line with the screen. Basically it is placed directly under the TV. In the acoustics of the center channel should include magnetic shielding and protection against parasitic sound waves. Housing such a speaker is usually made of wood or particleboard.Surround speakers can be divided into directional and dipole. The first type is different digital and multichannel music. They benefit from a clear sonic picture. Dipole speakers are used for playing audio material in the format of Dolby Surround or Dolby Pro Logic.The front speakers designed to reproduce the basic music and sound effects, which include low, medium and high frequencies.Kits designed acoustics for music, as they are able to reproduce the best sound. They have a different style, design, and a different value, through which it can buy almost any buyer. For proper selection of the speaker uses special program for calculating the acoustics. They allow the calculation of shells, filters, and various measurements, including impedance of the speakers, frequency response, harmonic distortion, etc
