Our Verdict
LG SN8YG
Sonos Arc
Depending on your listening habits, you may prefer either the Sonos Arc or the LG SN8YG. The LG is a 3.1.2 setup that reproduces a more extended low-bass thanks to its dedicated subwoofer. It also has EQ presets, a Full HDMI In port, and more wireless connectivity options. However, the 5.0.2 Sonos is better built, with better soundstage and surround performances. You can also upgrade it to the Sonos Arc with Sub + One SL Speakers.
