I am planning to buy home theater system to enjoy latest movies with good surround sound system for my room. But there are some terms used for the home theater system such as 5.1 or 2.1 home theater systems and I do not know the basic difference between these two. I want to enjoy gaming, movies, songs on my home theater, so guide me which one will be suitable for me. Anyone has any idea or know about it please share â¦â¦I would really appreciate â¦..thanks
