Question

Audio

Answer 1

You are building the wrong queries. Designations are written through a point usually - 5.1, 5.2. Details - on Wikipedia . Surround sound
A briefly - up to the point - the number of full-range channels, after the point - special effects channels (LFE usually, or a subwoofer in the common people). That is, 5.1 is 5 regular channels and 1 sub, and 5.2 uses 2 subs. Two is better, because allows you to more evenly distribute the bass, there will be no "buzz from the corner" effect.

Answer 2

5.1 - one subwoofer
5.2 - two subwoofers

Answer 3

5.2 more realistic sound. You don't hear bass on one side, but in stereo. It sounds cool. For a special large home theater room, I advise you to take 5.2
