Decision

What the current evidence supports

Agent-assisted assessment · independently reviewed · 2026-10-01

Suitable for everyday home theater if compactness and stronger standalone bass fit your needs.

Why
Independent tests confirm improved bass performance, while deep-bass impact and surround localization remain limited. Software tuning and TV connectivity can affect the experience.
Next
Audition with your TV and room, compare Trueplay settings, and consider a separate subwoofer if deep bass is essential.

Constraints

Blockers

  • Standalone deep bass falls short of a dedicated subwoofer.
  • No HDMI passthrough; the soundbar occupies a TV HDMI port.
  • DTS:X support is absent despite basic DTS compatibility.
  • Setup and tuning depend on the Sonos app and network.
  • Room acoustics and tuning affect bass and spatial performance.
