What is included in typical home theater systems?
It can be difficult to say what is "typical" in home theater systems, since the term is used in several different ways. Home theater systems used to involve expensive, large-scale remodeling projects that included large projection TVs, built-in speaker systems and integrated light and climate controls. Those are still common.
Less expensive home theater systems have gradually become available that involve little or no remodeling to install. These home theater systems usually include multiple surround-sound speakers and an audio receiver, which distributes multiple channels of sound data to the speakers. The audio receivers may or may not include a built-in DVD or Blue-ray disc player.
