The VIZIO V51-H6 is a complete 5.1 channel home theater soundbar system featuring a 36-inch soundbar, a dedicated wireless subwoofer, and two satellite surround speakers. Designed to deliver immersive home theater audio without complicated wiring, the system produces a neutral sound profile that works well for TV shows, movies, and music, with enhanced bass from the wireless subwoofer.

The soundbar decodes Dolby Audio 5.1 and uses DTS Virtual:X processing for a wider soundstage. Connectivity includes HDMI ARC for a single-cable TV connection and an optical audio input for additional sources. Bluetooth allows wireless music streaming from smartphones and tablets. A discrete center channel driver anchors dialogue clearly, and the Dialogue Enhancement mode further improves speech intelligibility. TruVolume automatically maintains consistent volume levels, making it ideal for late-night viewing. Four EQ presets let users tailor the sound to their preference.
