These are not really the same size class, and that is the honest framing here. The Sonos Arc Ultra ranks #1 of 27 all-in-one soundbars by sound quality at $1,099; the Sony Bravia Theater Quad ranks #8 of 10 surround sound soundbar systems by sound quality at $2,398.
Why pick the Sonos Arc Ultra: The Arc Ultra fills a living room with clear, well-placed sound from a single bar, and dialogue stays easy to follow with adjustable speech enhancement. The tradeoff: It cannot decode DTS:X, so Blu-ray discs with DTS tracks fall back to a simpler mix.
The case for the Sony Bravia Theater Quad: A fully wireless four-speaker Atmos system that sounds clean, crisp and cohesive, with clear dialogue and convincing height and surround placement. The catch: It ships without a subwoofer, and bass lacks weight and impact, so explosions and scores feel light unless you add an optional Sony sub.
Buy the Sonos Arc Ultra at $1,099 if you want an all-in-one soundbar. Buy the Sony Bravia Theater Quad at $2,398 if you want a surround sound soundbar system instead.
