Vizio SmartCast 38” 2.1-Channel Sound-Bar System (Mfr. Refurb.)

This two-speaker sound bar projects immersive audio during movies, shows, and sporting events, while its wireless subwoofer pumps out deep bass notes that drive home the action. The system also features the same technology as Google Chromecasts, letting you stream music, podcasts, and other content directly from your smart device to the TV and speakers.

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 streams music wirelessly from a compatible device, meaning your smartphone, tablet, or laptop never has to be tethered to other electronics to play songs or podcasts. In turn, that wireless connections lets you double as DJ while doing whatever you please, such as mingling with guests, cleaning the house, or doing yoga.

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.

About Vizio

Vizio launched in 2002, when rival companies had already been selling TVs for decades. Despite being a relative newcomer to the TV market, Vizio 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 many 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.

Item is a little spotty. Decent sound. Instructions are a little basic, but accurate enough. Took some tweaking to make it work & sync with my TV. Bought it because I have a Vizio TV and buying like products always improves functionality. The “True Surround” seems bogus to me, but the subwoofer is pretty legit.

It has problems with sound levels when using 3.5 rca cables It could be TV or Computer fault and when using bluetooth the sound stops for a second and resumes every five minutes. I can live with it but Im sure knowone else will. Also make sure you disable energy star, it turn off the sound bar after a half hour. The sound is better than what i was using.
