Consensus

our Verdict

The Vizio M Series M51ax-J6 suffers some downsides, such as latency issues, subpar Voice Assistant integration, and potential connectivity problems, such as periodical Bluetooth dropouts and connection failure with the subwoofer and rear speakers.

Additionally, the instructions for pairing can be confusing, and it constantly seeks pairing options Soundwise, it has a powerful and immersive audio experience with Dolby Atmos support.

Its neutral sound profile and customizable options cater to various audio content. Its bass is thumpy and impressive, but the treble isn’t crisp and overpowered by the bass.

While the soundbar has a good stereo soundstage, it lacks advanced sound enhancement features like a graphic EQ. The build quality is sturdy and has nice physical button controls, but the fabric coverings may not be the most durable.

ReasonS to Buy

  • “Powerful and balanced sound quality
    • The soundbar excels both for movies and music, as it comes with Dolby Atmos support and plenty of sound customization options to adjust bass and treble. It delivers a dynamic soundstage with booming bass, clear mids, and high yet balanced trebles.

  • Good surround sound
    • The soundbar delivers a high-grade 5.1 surround sound setup, including discrete surround speakers and a subwoofer. The overall profile is powerful for cranking up movies and music while providing a neutral sound and accurate sound.

  • Voice Clarity
    • With an excellent center channel, the soundbar excels for dialogue-heavy content, like TV shows. Additionally, the soundbar features a dialogue enhancement feature to focus sound performance on vocal frequencies, making them more clear.

  • Bass Response
    • The dedicated subwoofer provides powerful bass for music with low frequencies and high-quality movie content, specifically action sequences.

Reason to Avoid

  • Poor latency and limited connectivity options
  • Lacks smart features
    • The soundbar isn’t as functional as others in the category, given it lacks a built-in voice assistant or a dedicated smart app to control via a smartphone.

  • Subpar remote
    • The small control panel on the remote is hard to see, making it difficult to navigate and frustrating.
