home theater: A master piece
The master piece, the home theater is our goal to the next level of entertainment, a complete guide of every aspect of this beauty.
The goal of the home theater is to duplicate, in your own home, the surround sound envelopment and integration of picture, drama, and sound that you experience in a commercial Dolby Surround movie theater, only on a smaller scale.
Usually it consists of a pair of front left and right 
speakers on either side of the TV, a center-channel speaker on top (or beneath) the TV set to anchor the actors dialogue at the TV screen no matter where you sit, a pair of smaller surround-sound speakers to either side of your couch that carry all the effects and ambient sound of a movie or TV show-street noises, planes flying, jungle sounds, the noise of rain, thunder, or crickets, distant explosions or rumbles of tanks, and all the myriad of other sounds that make up a complicated movie soundtrack, including, of course, the movie score, the music and rock songs that underscore the action on screen. Lastly, most of them add a subwoofer , typically a square black box that produces ultra-deep bass sounds-rumbles, storms, deep musical bass and the like.
If you've kept count, that's a total of six home entertainment speakers , including the subwoofer , and it comprises "5.1-channel" sound” (the .1 is the subwoofer bass channel). But all the speakers necessary has to be big. Because the subwoofer carries much of the low bass energy, the other speakers can be compact and visually unobtrusive, no larger than a hardcover book.
To this mix, you must add a Dolby Digital Surround Sound Audio/Video receiver, which contains all the circuitry to "decode" the DVD or videotape movie soundtrack and effects, plus five built-in amplifiers for each of the five loudspeaker channels (the subwoofer always has its own dedicated built-in amplifier). And finally, you need a DVD player. (You can use a Hi-Fi stereo VCR, but it will only deliver analog Dolby Surround, not 5.1-channel Dolby Digital.) and less, you want add more speakers.
Note:
If you want to save some money in your next purchase, I suggest to buy a home theater in a box that buy every piece of your home theater ( although some home theaters in a box don’t give you the best quality sound and could limited to you what you just have in the box nothing else.)
