Sonos Arc Ultra vs Sony Bravia Theatre Bar 9

Both are premium single-bar Dolby Atmos soundbars with room calibration and no subwoofer in the box. The Sonos Arc Ultra leans on its Sound Motion architecture, 9.1.4 processing and a wide Sonos ecosystem, and owners praise dialogue clarity and music performance. The Sony Bravia Theatre Bar 9 packs 13 drivers, 360 Spatial Sound Mapping and full HDMI 2.1 passthrough with 4K120, VRR and ALLM, which matters if you game on a PS5 or Xbox. Pick the Sony for a gaming and movie setup with a Bravia TV; pick the Sonos for the cleaner design, the app and multi-room system, and the option to add a Sub and Era 300 rears later.

• Choose the Sonos Arc Ultra if you want a sleek bar that doubles as a music speaker in a Sonos multi-room system and you plan to add a Sub and rear speakers for full surround.
• Choose the Sony Bravia Theatre Bar 9 if you game or watch a lot of 4K/8K HDR content and want HDMI 2.1 passthrough, DTS:X and IMAX Enhanced support, especially with a Bravia TV.
