The “Focal Idea” behind having a home theatre system is to make your motion picture viewing experience at home as close to a “Cinema” experience. For this, you will need large Plasma, LCD, LED TV or a HD Projector with screen for its viewing. It all depends on the size of your room; you should be able to set up a screen that fits the width of your room.

“Audio-Video Receiver” is the heart of your home theatre system. It is the component to which all the other AV sources of the systems are connected. It is the AV receiver’s job to identify the signal it receives and send it to the correct section of the home theatre system to be processed. This includes sending multi-channel audio signals to the correct speakers in the room. An AV receiver consists of three sections. The first is the AV receiver which is the Tuner (radio stations). The second of the receiver is a preamplifier; this section determines the source of an audio or video signal and directs it to the correct output source. The third section is a built-in multi-channel power amplifier which amplifies audio signals before sending it to the multi-channel speakers in the room.
These days anyone can purchase their own Audio Visual system with a Blu-Ray or DVD player, home theater receiver, five to seven tonally matched speakers and with a subwoofer. Sometimes it is advisable to allow your audio visual requirements and value for money decision making to your Home Theatre consultants. Audio Visual equipment manufacturers offer completely integrated home theater systems designed to take the guesswork out of the home theater equation. A full-size AV component system might be excellent for individuals with dedicated home theater rooms. But what if someone just wants to enjoy the basics of movie with low budget surround sound?
The Options are there for anyone and budget Home theatre systems which are also known as “Home-Theatre-in-a-box” or “all-in-one” as it is known is an integrated home theater package which ” puts together ” a choice of DVD or Blu-Ray player with multi-channel amplifier, these includes a Surround Sound decoder, a Tuner, and other features like color coded speaker wires and connectors, a remote control, a set of five miniature surround sound speakers or more commonly, a small Subwoofer with just Left and Right speakers.

Even colour-coded cables for the speakers are supplied, making the complete set-up process easy and reliable.
Budget Home Theatre systems generally use miniature “satellite” speakers, and they usually come with a subwoofer. The small size amplifiers and speakers in lower-cost systems mean that you will not be able to obtain surround dynamic satisfaction in a large room. The cheapest Home-theatre-in-a-box (audio only) systems normally cost at about $200/-. They use a single full-range driver in the satellite speakers, instead of a two-way design with a tweeter to provide a cleaner high-end. Also with small subwoofers supplied it cannot recreate the truly earthshaking sound that movie-watchers will expect. Small speaker drivers used in cheap satellite speakers are limited by the amount of low-end they can produce. Similarly, the subwoofer is limited in the amount of high-end it can produce, and you really don’t want the subwoofer to produce much high-end. So, there will be a frequency gap between the lowest frequencies produced by the satellite and the highest produced by the subwoofer. On the other hand, during playback you will notice that “Gap” in the upper bass to lower midrange frequencies. So, you are only getting what you have paid for.
More expensive Home Theatre systems can even provide playback of DVD-Audio and SACD discs, for high-resolution audio its like hearing a first generation live sound.
