Our Verdict
Sonos Beam
LG SP9YA
The LG SP9YA is a better soundbar for most uses than the Sonos Beam. The LG is a 5.1.2 setup that comes with a dedicated subwoofer. It can reproduce a more extended low-bass and has a better surround performance. Unlike the Sonos, it supports Atmos content and has a Full HDMI In port for high-quality passthrough. That said, the 3.0 Sonos has a more compact design. It also offers better soundstage and center performances, so it's a solid choice for users who listen to lots of dialogue-centric content and don't want to use up a lot of space in their setup.
