Vizio M512a-H6B-RB 5.1.2 Dolby Atmos 40" Soundbar System- Certified Refurbished


Arrival time – ET 8pm Experience a new dimension of sound that truly surrounds with the new M-Series™ 5.1.2 Home Theater Sound Bar with Dolby Atmos® and DTS:X® from VIZIO, America’s #1 Sound Bar Brand. Its 11 high-performance speakers with separate tweeters and woofers deliver pristine clarity and ample volume. Inside the sound bar are two upfiring speakers—the key to Dolby Atmos and DTS:X cinema sound—that reflect accurate overhead audio off your ceiling to deliver life-like 3D surround sound that complements today’s 4K picture quality. A dedicated center speaker assures crisp, clear dialogue within a smoother front soundstage, and the adjustable Dialogue Enhancement EQ further increases vocal clarity so you can hear every word. A pair of discreet surround speakers with volume EQ fills any room from front or back, plus the mighty 6” wireless subwoofer rocks the house on movie night with deep bass that really booms.

With the M-Series 5.1.2, Dolby Atmos and DTS:X soundtracks bring cinema-quality overhead surround to movies at home, and video games now have heart-pounding, life-like 3D sound that comes from all around you—even from above—so you can hear every detail and immerse yourself like never before. This is the difference between watching and truly losing yourself in the moment. And for non-Atmos/DTS:X content, DTS® Virtual:X™ adds thrilling floor-to-ceiling virtualized sound, putting you in the middle of the action or front row at the finest concert hall. The sound bar is designed to deliver the highest possible audio/video quality from all connected sources, with HDMI eARC that enables cutting-edge 4K Dolby Vision pass-through to the TV. (An HDMI cable and all audio cables are included right in the box.) This feature also lets you control the sound bar with your TV remote.
Its modern, low-profile style features an easy-to-clean charcoal gray texture that’s ideal for any living space. For an equally elegant, hands-free smart experience, the M-Series 5.1.2 is also Voice Assistant-ready, so you can connect your own voice assistant (sold separately) and operate it right through the sound bar for upgraded audio. And for further wireless ease, stream your favorite playlist from your phone with Bluetooth. With these advanced features and its cinema-quality surround sound, the VIZIO M-Series 5.1.2 Home Theater Sound Bar with Dolby Atmos and DTS:X lets you bring home the true movie theater experience like never before.
