The audio market has really evolved in the last decades. Today you can’t enjoy the great sound of a live performance only at a concert, or in a disco, but you can also enjoy it right in your own room. Due to the powerful speakers combined with subwoofers and other components, today you can enjoy a very rich and powerful music experience right at your home.



But this is not all…these days you can also take the great sound of a movie from the cinema, right into your own room. And to do this you might need a home audio system (also known as “home theater system” or “home cinema system”). These devices are meant to bring the video and audio experience from a cinema to a private house. Usually a home audio system is composed out of many components, that combined will bring that great movie experience. Some systems come will all the required components, while others have just some of them…but you can even make your own system and combine elements from different producers.



For the video experience you will need 2 things: a TV and a movie player device. You can use a regular TV for your home cinema system, but it will be much better if you will use a HD (High Definition) TV set. If you have a room big enough, and you can afford it, you can even buy a video projector and a projection screen, and this will really look like a cinema right in your own home. But a HD TV will be enough, and you can enjoy a great quality of the image with it.

Of course you will need something to play the movie from. You can use a computer, but if you have the home cinema system in another room rather than the room with the computer, you can use a DVD player. Usually a home cinema system has an included device like this, that plays a lot of video and audio formats, such as CD, DVD, R 5, Blu Ray, MP3, WMA and others.

So now you have your big and flat screen just like the one at the cinema, but for the experience to be complete you will also need a powerful sound…just like the one from a cinema. And at this part the home cinema systems are quite good, and they usually have 6 or 8 speakers. The one with 6 speakers is a 5.1 system. This one is composed out of 4 satellite speakers, a center channel and a subwoofer. The satellite speakers will focus on the mid range sound, and because of the way they are placed in the room (a speaker in each corner), they will give you some great surround feelings.



So when watching a movie you can feel what the actor is feeling, for example that he is attacked from behind. The center channel will focus mostly on the high frequency sounds, such as the voices of the actors. The center channel will be placed in front of you (usually under the flat screen), so you will hear the voices very well. And finally, for the audio experience to be complete, you will also need a subwoofer. This speaker will focus just on the low and deep sound frequencies, in another word the bass. So whenever it is an explosion in the movie, an earthquake, a gun shot or something like this, the subwoofer will bring a deep sound. And if you have a powerful subwoofer, turned at a loud volume, you can easily make your room and your windows shiver. If there is an explosion in the movie, your neighbors might think that something exploded in the building :)
