Today we will discuss some questions concerning acoustic systems in your home and their influence on your life! To these questions the whole article or may be the ensuing articles will be about! The quality of sound which will be produced by your acoustic system will depend on components of the whole acoustic set. This article will help beginners and probably you to understand what are a typical acoustic system and what components it is composed of. The systems of home theatres are becoming more popular today because more and more people want to have a system of surrounding sound in their home. And from great variety of devices which are offered by a market today we need to choose something and of course this “something” should be the proper choice with great quality and optimal price in order we could enjoy our acquisition long time. However exactly on this step many of us do many mistakes in their choice because few of us know special characteristics of different models. So let us begin from the very beginning!
For the full-fledged operation of all elements of your home theatre four main components are used usually: speakers for frontal channels, for rear channels, the acoustics of central channel and sub buffer. For the dubbing of frontal stereo channels in home theatres an ordinary stereo pairs which is usually included into any Hi-Fi system is used. Nothing new was created in this sphere.

With the Dolby Pro Logic format appearance the stereo pairs had acquired acoustics for dubbing of central channel. Before this time effect-monitors have been used in big cinema theatres. On their basis “domesticated” speakers have been created. That time their diapason of reproduced sound frequencies was deliberately limited because of specific peculiarities of the Dolby Pro logic format. With emergence of digital technologies in sound recording (in particular DVD discs) the situation has changed. The requirements to the central channel became stricter as to frontal channels. However numerous of companies are convinced that central speaker the most works on dialogues and exactly for this reason the one of the main requirement to central speaker is clearness in middle frequencies transmission which means the credibility of actors’ voices reproduction. According to shape the central speaker is different from other acoustic system elements. It is often a horizontal positioned box with two dynamics. The principle of sound waves diffusion of such kind of acoustics consists in even and nondirectional emission of frequencies in horizontal flatness.
