Our Verdict

Sonos Arc

LG SP9YA

Depending on your listening habits, you may prefer either the Sonos Arc or the LG SP9YA. The LG comes with a dedicated subwoofer that reproduces a more extended low-bass. Also, it comes with EQ presets for sound customization. However, the Sonos has better soundstage, surround, and Atmos performances. Also, it can be upgraded to the Sonos Arc with Sub + One SL Speakers.
