Our Verdict
Bose Smart Soundbar 300
Bose Smart Soundbar 900 with Speakers + Bass Module
The Bose Smart Soundbar 900 with Speakers + Bass Module is better than the Bose Smart Soundbar 300. The 900 is a full setup with a dedicated subwoofer and satellites, while the 300 is just a standalone bar. The 900 supports Dolby Atmos content, and it has better soundstage and surround performances. It can also reproduce a more extended low-bass. There are even some more sound enhancement features available, like room correction. However, if you're low on space and just want to watch dialogue-centric content like TV shows, the 300 is still a solid choice.
