Vizio 38” 2.1-Channel Bluetooth Sound Bar with Wireless Subwoofer (Refurbished)

Immerse yourself in your favorite movies and music, feeling every rumble and high note, with this Bluetooth sound bar that features a wireless subwoofer and surround sound-like feel.

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.

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.

Wireless Subwoofer: Deep Bass, Flexible Location

The subwoofer heightens the drama of movies and TV shows by sending the thud of footsteps or the roll of thunder rumbling around the room. Its wireless connectivity and single power cord mean it won’t contribute to unsightly cable nests. As an active subwoofer, it contains its own speaker driver and amplifier, which results in bigger, more room-filling sound than that from a passive model.

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.

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.

The sound bar malfunctioned a little over one month after purchase. It is the second Vizio product that I have purchased and they both malfunctioned. Never again

product looks like new and works well. Wish it had a little more power. For the price you can't beat it though.

Absolutely love it. Rich base, clear sound that fills the room, all from a sound bar. Excellent! The blue tooth sub is freaking sweet... just plug and pair. My family is very pleased.

Unfortunately when it arrived it would not power on. I'm in the middle of working with Vizio to get it resolved/replaced but they are responding at a snails pace. First item ever off Groupon that I've had a problem with.
