VIZIO M51ax-J6B-RB 5.1 Home Theater 36" Soundbar System Dolby Atmos - Certified Refurbished


Immerse yourself in everything you watch with the VIZIO M-Series 5.1-Channel 36" Soundbar System. It features a soundbar with discrete left, right, and center channels, plus two satellite speakers and a 5" wireless subwoofer to provide a true surround sound effect with low bass impact. The satellite speakers are wired directly to the subwoofer, so if the subwoofer is placed near the back of the room, front-to-back wiring isn't necessary, simplifying installation. DTS Virtual:X sound technology creates a 3D soundstage for your movies and TV shows. Bluetooth connectivity is onboard for pairing with your compatible device and wirelessly streaming your audio content. Its HDMI port is eARC-compatible, so you can hear display-based audio from built-in apps like Netflix and YouTube through the soundbar system. A backlit remote control is included as an added convenience.

    A 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.

    Nine High-Performance Drivers

    With nine high-performance drivers that each deliver sharp clarity and powerful sound, the M-Series proves there's strength in numbers. It even has a dedicated center speaker specifically for dialogue to ensure that what's being said is heard loudly and clearly, no matter how intense that action scene is.

    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.

    5" Wireless Subwoofer

    The compact wireless subwoofer can be placed almost anywhere to deliver booming bass that shakes your space down to a thunderous 50 Hz. The satellite speakers connect to the subwoofer via RCA cables, eliminating the need for wires running from the front to the back of your room.

    Versatile Surround Speakers

    Turn your space into a cinematic home theater with versatile surround speakers that put you in the middle of a dynamic sound experience.

    Front Surround Mode

    The satellite speakers can be placed in the front of the room to create a wider sound stage and immersive surround sound that hits you where you live with powerful resonance and impact.

    Dual Stereo Mode

    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 nine high-performance drivers simultaneously for maximum room-rocking impact.

    Sleek Design

    With an elegant low-profile design that houses nine powerful drivers and docks seamlessly with select VIZIO TV stands, the sleek charcoal-toned M-Series soundbar system strikes the perfect balance of style, strength, and sophistication.

    Backlit Remote

    With preset EQ modes for gaming, movies, music, and more, the backlit remote makes it easy to customize your audio settings for perfect sound every time, even in the dark.

    Amplify Your Assistant

    Amplify the voice of your favorite virtual assistant by easily connecting it to the M-Series soundbar. It's always on and ready for a command, and will automatically lower the volume of what's playing so you can hear the voice assistant's response clearly.

    Bluetooth Built-In

    With built-in Bluetooth connectivity, it's easy to stream music, podcasts, and more from popular apps like Spotify, Pandora, and iHeartRadio.

    HDMI & eARC

    HDMI and eARC connectivity send the highest-quality audio from your TV and allow you to conveniently control the soundbar with your TV remote via CEC.
