Another major component of a home theater system that depends on the size of the room is the speaker. The number of speakers for your home theater system is dependent on the size of the room. You may add up to six speakers from the basic three speakers if you want a more lifelike sound. Adding a subwoofer may also be good to achieve a complete surround sound like in the movie theaters. Three speakers should be the minimum; you may go up to six if the room is big.
