Our Verdict

Sonos Arc

Klipsch Cinema 400

The Sonos Arc is better than the Klipsch Cinema 400. The Sonos is a 5.0.2 setup, is better built, and supports Dolby Atmos content. It has better soundstage, center, and surround performances, and it has room correction. Unlike the Klipsch, it has built-in voice assistant support. The 2.1 Klipsch has a dedicated sub that helps reproduce a more extended low-bass.
