## What reviewers say

**Bose Smart Ultra Soundbar** — Two whitelisted hands-on testers (Tom's Guide, What Hi-Fi?) reviewed this exact model; neither published lab bench measurements. Both praise the wide, immersive Dolby Atmos soundstage and solid build, but flag a congested/harsh midrange that undermines music and dialogue, and note the AI Dialogue mode can over-compensate. (2 sourced reviews.)
