Our Verdict
Sonos Arc
Samsung HW-A450
The Sonos Arc is a better soundbar than the Samsung HW-A450. The Sonos is a 5.0.2 setup, is better built, and offers better soundstage, center, and surround performances. It also supports Dolby Atmos content and comes with a room correction feature. You can even upgrade it to the Sonos Arc with Sub + One SL Speakers for better performance. However, unlike the Sonos, the Samsung has a graphic EQ and presets for sound customization.
