Vizio 5.1-Channel SmartCast Home Theater System (Manufacturer Refurbished)

Thanks to built-in Google Cast technology, you can wirelessly stream favorite albums straight from your smartphone or tablet to this sound system. Rich sound from the 38” bar and rumbling bass from the subwoofer add new dimensions to familiar tunes and movie soundtracks alike.

Lifelike Sound from Multiple Angles

5.1-channel surround sound makes the cheers of a packed stadium, the rumble of a far-off tank, or the beeps of an animated robot’s circuits feel like they’re happening in your living room. This multi-speaker setup creates such 3D-like sound by balancing distribution between one center, two front, and two rear speakers. For an even greater sense of immersion, a dedicated subwoofer colors the sound with deep yet not-overwhelming bass that heightens everything from the soundtrack to environmental noises.

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.

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.

Works well and sounds good. The only nit I have is that if I don't turn it on before I turn on the TV, the CEC link doesn't work and I can't control the volume from my TV remote.

Product looks like new. The sound is good, not as good as a/v receiver, but lots less. I need more time to play with different speaker placements and settings before I really can rate these.
