Our Verdict

Bose Smart Soundbar 900

Bose Smart Ultra Soundbar

While the Bose Smart Soundbar 900 and the Bose Smart Ultra Soundbar look similar, some differences exist. The Smart Ultra has a lower bass extension to help add a touch more thump and rumble to your audio. It also has an AI Dialogue tool to help enhance voices. However, the Smart Soundbar 900 has a less bright sound overall.
