Bookshelf Speakers – speakers mounted on special racks at a height of optimum listening, that is one in which the speakers will be head high at the head listeners. Designed for highs and mids. In larger rooms, the sound of these speakers will be slightly blurred, so a bunch of them are added to interior columns. Floorstanding Speakers designed to play the major music and sound effects.

Central acoustics – is designed to reproduce the center channel and usually located between the dynamics of the right and left channel. When playing a movie for example, through the central acoustic playing mostly all dialogue. The result is that high-quality speaker system to be consist of two floor-front speakers, center speaker placed between them, two rear bookshelf acoustician and a subwoofer.
