Product Description

Model #: M21d

The redesigned M-Series™ All-in-One 2.1 Home Theater Sound Bar from VIZIO, America’s #1 Sound Bar Company, combines supreme convenience with powerful performance.


  • Thrilling sound is achieved with separate tweeters and woofers, plus built-in dual 3” subwoofers, all in a striking angular shape with a dark charcoal finish. There are no additional speakers or cables needed.
  • HDMI connectivity offers the highest-quality audio with quick and easy setup, allowing you to control the sound bar with your TV remote. (HDMI and all audio cables included.)
  • 4K HDR content is enhanced with Dolby Audio™ for the highest-fidelity sound, and DTS® Virtual:X™ creates an immersive experience with room-filling, floor-to-ceiling, virtualized 3D sound that transforms music into a live concert, or a sci-fi film into an intergalactic adventure.
  • The M-Series™ All-in-One features the all-new Voice Assistant Input that gives you the convenience of a voice assistant you are already accustomed to (sold separately) and lets you operate it right through the sound bar for upgraded audio.
  • You can also wirelessly connect your phone or any compatible Bluetooth device for high-quality music streaming.
  • The VIZIO M-Series All-in-One Sound Bar is a hassle-free, plug-and-play audio solution that does the job of many speakers, turning your living room into a captivating home theater.

Great Sound!

The sound bar is great. It gives that deep sound with the 3 mini subwoofers that it has, and the price is not bad at all. I will upgrade with the 5.1 Sound Bar later but if your looking for good sound and don't have the room for the 5.1, this one I do recommend.

Good overall bar. Decent sound, but expected for the price. Better than the TV speakers. Only "complaint" is the volume "steps" could be a little closer, they seem to make more jump in range per click than I'd like, but that's a personal preference, and not a deal breaker by any stretch.
