Our Verdict

Sonos Arc Ultra

LG Sound Suite H7

The LG Sound Suite H7 and Sonos Arc Ultra are similar standalone soundbars that you can expand with additional speakers and a subwoofer. The LG's integrated subwoofers output more bass than the Sonos's, but the stereo frequency response of the bar isn't as balanced relative to our in-room target. If you care about customization, the LG is the better option, as the bar supports more sound enhancements like a graphic EQ.
