Sonos Arc Ultra review

Arc Ultra is the soundbar to buy if you want something close to a home theater from one box. Sonos lists 14 drivers: nine silk-dome tweeters, two of them firing upward, six midwoofers and a Sound Motion woofer, a four-motor, dual-membrane design that Sonos says delivers deeper bass from a flat cabinet. The result is a 9.1.4 Dolby Atmos claim, the highest channel count of any single bar here. Dialogue is well served too: Speech Enhancement uses AI to detect voices and has four levels, and Night Sound keeps loud scenes in check. Setup is a power cable, the included HDMI cable and the Sonos app, and the TV remote keeps working. Trueplay tunes the sound for your room, and WiFi, Bluetooth and AirPlay 2 cover music. The catch is price: $1,099 buys a lot of bass and width that a viewer who only wants clearer news broadcasts does not need. For large rooms and movie fans, it is the premium choice.
