Dolby Atmos Speakers
"Dolby Atmos is a surround sound technology that transports you into the story with moving audio that flows all around you with amazing realism. There are many ways to get Dolby Atmos electronics within your home for the right setup. Such as with a Dolby Atmos enabled sound bar, or as few as six speakers in a conventional home theater system, you can enjoy the magic of Dolby Atmos.
To add overhead sound, you can use two or four speakers mounted in or on the ceiling, or use Dolby Atmos enabled speakers that fire sound upward toward the ceiling, from where it's reflected back to the listening area."
