Sound bar systems deliver immersive audio without running wires across the room or setting up extra speakers. Some sound bars can be mounted to the bottom of your TV, mounted to the wall or simply sit on a shelf below your TV. Select systems even include a subwoofer to deliver greater impact to your favorite movies or sports events.
A home theater in-a-box system is usually the simplest and least expensive way to add multi-speaker surround sound to your HDTV. They include five compact speakers, a "media center" (surround sound receiver with a built-in DVD or Blu-ray Disc player), and a small subwoofer.
A system built from separate components is the best way to experience home theater and your favorite music. These systems typically involve up to seven small to large speakers, depending on the individual system. You'll also need a subwoofer, a home theater receiver, and a disc player (like a DVD or Blu-ray player). Component systems can also offer greater flexibility - like adding speakers in another room or outdoors.
