Our Verdict
Sonos Arc with Sub + One SL Speakers
LG SP9YA
The Sonos Arc with Sub + One SL Speakers is a better soundbar than the LG SP9YA. The Sonos comes with discrete surround speakers that offer a better surrounds performance. It's also better-built, with better soundstage and Atmos performances. It gets louder, too, though it has more compression at max volume. However, the LG has a more neutral sound out-of-the-box, and it comes with EQ presets, a Full HDMI In port, and more wireless playback options.
