Our Verdict

Bose Smart Soundbar 900 with Speakers + Bass Module

Bose Smart Ultra Soundbar

The Bose Smart Soundbar 900 with Speakers + Bass Module offers a better overall experience than the Bose Smart Ultra Soundbar. The Smart Soundbar 900's full setup with satellite speakers and a subwoofer gives it a fuller sound that's more immersive, especially when it comes to surround and Atmos content. That said, if you're low on room, the Smart Ultra isn't a bad choice, thanks to its integrated subwoofer, which helps add punch and warmth to your content. It has the same audio format support as the full setup, too.
