Feel the power of premium audio with the newly-designed M-Series™ 5.1 Home Theater Sound Bar with Dolby Atmos® and DTS: X® from VIZIO, America’s #1 Sound Bar Brand, made to complement today’s ultra-lifelike 4K picture quality. Its nine high-performance speakers with separate tweeters and woofers deliver pristine clarity and rich sound from Dolby Atmos and DTS:X cinema sound technologies. Also included are low-profile surround speakers that fill the room from front to back and a powerful 6” wireless subwoofer that rocks the house with deep bass. Together, they bring Dolby Atmos and DTS:X movie soundtracks to life in thrilling virtual 3D surround with a virtual height effect that seems to come from above in any room, and video games have heart-pounding new realism.

To customize the audio experience to your unique needs, Front Surround Mode lets you place the surround speakers in the front of the room for a wider soundstage in less space; or Dual Stereo Surround Mode sends left/right audio the main soundbar and the surrounds to bring dialogue closer. The soundbar is designed for the highest audio/video quality, with HDMI eARC connectivity that enables 4K Dolby Vision pass-through to the TV. (HDMI and all audio cables are included.) And for the convenience of hands-free control, it’s ready to work with your voice assistant device (sold separately). With all these advanced features and its high-performance sound, the VIZIO M-Series 5.1 Home Theater Sound Bar amplifies the action to transform any room into a captivating private cinema.
