Our Verdict
Samsung HW-Q800D
Sonos Arc Ultra
The Samsung HW-Q800D is a better-value soundbar than the Sonos Arc Ultra unless you lack the space for a discrete subwoofer or own other Sonos products. The dedicated subwoofer means that it has a better bass extension than the Sonos, and the rest of the frequency response is just as balanced. The Samsung benefits from a 7-band EQ, which gives you more scope for customization than the Sonos' bass and treble controls. The Samsung also features a full HDMI In port, allowing you to passthrough 4k signals at 60Hz. That said, the Sonos has the edge when it comes to soundstage, as it has a wider, more immersive sound. Its all-in-one design will suit those that lack the space for an expanded home theater setup.
