All major movie houses, theatres, home entertainment environments, gaming, arcade and other public and in-house presentation areas today are using 7.1 surround sound systems for their enhanced audio entertainment needs. 7.1 Surround sound is the increasing of the dimension of your sound (or sound waves). In other words you take the standard one dimensional audio production, referred to as mono / Left-Right, and turn it into multiple dimensions, like two or three. This is the system you can install in your home. Sounds great doesn’t it??
