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.
