Why would a person need a home cinema when there are special cinemas with huge screens and surround sound, and you can visit them any day? The answer to this question can be obtained if you simply remember the necessary conditions and rules for visiting public cinemas. Often, while watching, you will hear unnecessary comments from other viewers behind you, loud laughter, grumbling or hissing - as soon as you start making your way to the exit during the session, for example, if you need to go out. And the acoustics often leave much to be desired.
