The Second Number, for instance, 2 in 10.2

 

The second number of a speaker system arrangement specifies the number of subwoofers in the surround system setup.

Commonly the second number will be one as most systems only have one subwoofer. However, occasionally you may come across a 2.

The reason is that some people prefer having two subwoofers to satisfy their needs for fuller bass.

 

The Third Number, for instance, 2 in 7.1.2

 

The third number of a speaker system layout specifies the height speakers, otherwise known as upward-facing speakers.

Height speakers are extra speakers usually placed on ceilings before the home theater.

These speakers introduce height to the surround system, enabling a wholesome three-dimensional sound effect.

For height speakers, the ceiling should be no higher than 14 feet.

In addition, you should place the speakers at a minimum of three feet on top of the right and left front speaker directly facing the listener.

Generally, people have two upward-facing speakers; hence, more often than not, the third number will be 2.
