Our Verdict
Sonos Beam
LG SN6Y
The LG SN6Y and the Sonos Beam offer similar overall performances. The LG is a 3.1 setup with a dedicated sub and can reproduce a slightly more extended low-bass. Unlike the Sonos, it has a Full HDMI In port for high-quality passthrough. However, the 3.0 Sonos is better built with a more compact design that some users may prefer. Despite its small size, it still offers a better soundstage performance.
