Vizio SmartCast 2.1-Channel Sound Bar System (Mfr. Refurb.)

This sound bar and subwoofer add depth to film dialogue and TV theme songs, but that’s just the beginning: they also stream audio directly from your mobile devices over a wireless connection.

Cast From Apps You Already Know and Love

All Vizio SmartCast audio products have Google Cast built in (the same technology behind Chromecast), allowing you to cast your favorite content from your phone to your ​​​​TV, display, or Sound Bars. Access millions of songs, podcasts, and more.​

Detailed Sound, Minimal Clutter

The 2.1-channel setup elevates your TV’s audio to give you an experience that’s closer to that of surround sound. Laterally placed speakers produce wider distribution and more realistic depth, creating a sense that the action is unfolding around you. The subwoofer intensifies the effect by adding rumbly low notes that most TVs’ built-in speakers can’t match. With only two components to install, the 2.1-channel setup strikes a much cleaner look than full-blown home theater systems.

Bluetooth: Stream Wireless Music, Internet Radio, and Podcasts

Bluetooth lets you stream wireless music from an enabled mobile device, leaving you free to mingle with guests, clean the house, or do yoga—all without interrupting the music. Moreover, Bluetooth plays your favorite songs over the system’s speakers, filling the room with richer sound than most smartphones, tablets, or laptops can.

Dolby Digital

Dolby Digital helps you feel the passion in an actor’s voice, the beat of a song, and the gravity of a video game’s final battle. It enhances everything from movies to MP3s by elevating what you’re most likely to hear, such as heated dialogue or an ominous door closing, while suppressing static and other background noise. The result is clear digital sound in everything from home theater systems to wireless headphones.

About Vizio

Launching in 2002, when rival companies had been selling TVs for decades, Vizio may be a relative newcomer to the TV market, but it hit the ground running. By 2007, it sold the most LCD TVs in America. Its runaway success is thanks in large part to its bread-and-butter HDTV, the LED-backlit 1080p set that can be found in most living rooms. Yet the company also takes chances on the latest technologies. In 2015, for instance, it launched what is arguably one of the most high-end sets ever produced—the $130,000 Reference Series, a 120” 4K set with support for more than one billion colors and integrated 5.1-channel surround sound. While the hefty price tag will deter most TV shoppers, Vizio will inevitably find a way to pack the cutting-edge technologies into a more consumer-friendly set—the approach to TV-making that brought it success in the first place.
