Product Description

Experience a new dimension of sound with the M-Series 5.1 Home Theater Sound Bar from VIZIO. Delivering next-generation immersive surround sound powered by Dolby Atmos and DTS:X for unprecedented realistic sound. Its modern design can be easily hidden underneath TVs for a clean finish. And wirelessly stream your favorite podcasts, shows and more with Bluetooth, using your phone or any compatible device. The dedicated Voice Assistant Input offers the convenience of a voice assistant you are already accustomed to (sold separately) letting you operate it directly through the sound bar for an upgraded audio experience.
  • Experience Impact - Experience the impact of state-of-the-art cinematic surround sound with Dolby Atmos and DTS:X.
  • New Dimension of Sound - Dolby Atmos and DTS:X technology take your surround sound to the next level by creating a sense of audio above you for a complete and truly multi-dimensional entertainment experience. DTS Virtual:X technology creates a virtualized floor-to-ceiling 3D sound experience, even with non-Dolby Atmos content.
  • Fidelity You Can Feel - Each M-Series speaker isolates a unique range of frequencies to achieve naturally deeper bass, more accurate highs and an extraordinary sound experience that's resonant, rich and clear.
  • Fill The Room - The compact wireless subwoofer can be placed almost anywhere to deliver booming bass that shakes your space down to a thunderous 50Hz.
  • Savor The Sound All Around - Turn your space into a cinematic home theater with versatile surround speakers that put you in the middle of a dynamic sound experience that's pretty much magical.
  • Versatile Speakers - They can be placed in the front of the room for a wider sound stage and immersive surround sound that hits you where you live with powerful resonance and impact.
  • Supersize Stereo - Elevate the music at your next house party to concert hall levels of quality with Dual Stereo Mode, which expands the stereo signal across all 9 high-performance speakers simultaneously for maximum room rocking impact.
