The Bose Smart Soundbar 900 is Bose's flagship soundbar, delivering true Dolby Atmos spatial audio through beam-steering technology that bounces sound off walls and ceilings to create height and width cues — all from a single, elegant bar below your TV. Its PhaseGuide arrays and up-firing transducers work together to expand the soundstage well beyond the physical width of the speaker. Alexa and Google Assistant are built in for voice control, and it connects via HDMI eARC for the highest quality audio signal. Paired with the Bose Bass Module and Surround Speakers, it creates a reference-quality home theatre.
