Supports Dolby Atmos and Atmos-encoded contentDolby Atmos makes it feel like your room is filled with sound from every direction, including overhead. Two custom-engineered up-firing dipole transducers, one on each end of the soundbar, are dedicated solely to overhead effects to create a sense of height.Bose TrueSpace technology for non-Atmos contentBose proprietary TrueSpace spatial processing intelligently analyzes signals other than Dolby Atmos, like stereo or 5.1, and up-mixes them to create an immersive 7-channel sound experience. The result is enveloping sound no matter what you watch.Looks as beautiful as it soundsWe obsessed over every detail to produce a soundbar that's every bit as astonishing as its sound.
