These sit in different size classes, so this is not a straight ranking comparison. The Samsung HW-Q990F ranks #2 of 10 surround sound soundbar systems by sound quality at $998; the Sonos Arc Ultra ranks #1 of 27 all-in-one soundbars by sound quality at $1,099.
What the Samsung HW-Q990F does well: This 11.1.4 system includes a wireless sub and two wireless rear speakers with up-firing drivers, giving movies a wide, enveloping sound field with real overhead effects. Watch for: In a direct comparison, a Sonos Arc Ultra system sounded more natural and its sub played deeper.
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 catch: It cannot decode DTS:X, so Blu-ray discs with DTS tracks fall back to a simpler mix.
Buy the Samsung HW-Q990F ($998) for a surround sound soundbar systems; the Sonos Arc Ultra ($1,099) suits a all-in-one soundbars instead.
