Sonos Arc Ultra vs Samsung HW-Q990H Soundbar

The Samsung HW-Q990H is the more complete home theater: it ships with a subwoofer and two rear speakers for true 11.1.4 surround, and its 756 W of amplification gives it far more headroom. The Sonos Arc Ultra is the better single-bar choice: one sleek unit, 9.1.4 spatial audio, and a polished app, with no satellites to place or power. Reviewers praise the Arc Ultra for clear dialogue and convincing bass, but some say the upgrade over the original Arc is modest. The Q990H wins on raw immersion and value per component; the Arc Ultra wins on simplicity and design.

• Choose the Sonos Arc Ultra if you want one clean bar under the TV, no rear speakers or sub to place, and the Sonos app and multiroom ecosystem matter to you.
• Choose the Samsung HW-Q990H if you want real surround with rear speakers and a subwoofer in the box, and you have room behind the couch to place them.
