Our take on the Sonos Arc Ultra & Sonos Sub 4 Wireless Subwoofer (White)

A two-piece Sonos home theater set: the Arc Ultra soundbar paired with the Sub 4 wireless subwoofer. The Arc Ultra uses Sonos Sound Motion technology to produce deeper bass and clearer dialogue from a slim bar, and it supports Dolby Atmos for height effects. The Sub 4 adds dual force-canceling woofers for low-end punch with little cabinet rattle. This bundle suits people building a serious movie and music setup who want big sound without a receiver and separate speakers. Against a single premium soundbar, it delivers noticeably more bass and scale; against a full surround system with rear speakers, it still lacks true rear channels unless you add Sonos rears.
