Some Dolby Atmos soundbars come with wireless surround sound speakers, which help to create a fuller sense of immersion in the sound. While these aren’t completely necessary – many Dolby Atmos soundbars are designed to deliver a “wraparound effect” where the sound extends beyond the width of the TV screen – our testing experience has shown that systems with surround sound speakers offer a performance advantage over ones that don’t include them.
Same as with optional wireless subwoofers, Dolby Atmos soundbar makers, including Sonos, Bose, Samsung, LG, and Sony offer wireless surround sound speakers, and these can be added to the system at a later date to upgrade performance.
