## What reviewers say

**Sony Bravia Theatre Bar 9** — Only one whitelisted tester (What Hi-Fi) yielded a verifiable review body for this exact model (Sony Bravia Theatre Bar 9 / HT-A9000). What Hi-Fi rates it a five-star Award winner: a clear upgrade on the three-time Award-winning HT-A7000, with superb clarity, detail and dynamics, and the most convincing Atmos it has heard from a standalone soundbar. Trade-offs are a slightly clinical voicing with less warmth than the predecessor, occasionally over-pronounced deep bass at high volume, no display, and only one HDMI input. No lab measurements were published. (1 sourced review.)

**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.)
