Home theaters 7.1

7.1

— the development of the idea of surround sound, laid down by the 5.1 format. Includes two front channels, one centre, two rear, subwoofer for bass and extra bass, and two additional channels. Actually, different versions of the 7.1 format. differ precisely in the location of these two channels: they can complement the front speakers to shift the sound vertically, be placed on the sides of the viewer, etc. Anyway, 7.1 systems provide more authentic surround sound than 5.1, but they are more difficult to set up and more expensive.
