Vizio 40” 5.1-Channel Bluetooth Sound-Bar System with Wireless Subwoofer (Manufacturer Refurbished)

It doesn’t take a complicated setup with a mess of wires to create theater-worthy audio in a living room, and this sound-bar system serves as proof. The sleek bar houses a trio of speakers that generate clear, detailed dialogue and treble, while the wireless subwoofer—which can be placed anywhere in the room—heightens action sequences and party music with booming lows.

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.

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.

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.

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.

I have a Vizio flat screen, so thought purchasing a Vizio sound system would be a good complement. Product was well packed, and installation was straight forward and easy. The connections were seamless. The control remote was used to adjust the surround, bass, treble, balance, subwoofer etc. I'm happy with it.

The main speaker pops every 2 minutes. Not like a humming, but just a tiny pop.

The Vizio sound bar was easy to set up. I mounted the sound bar above the tv using the supplied brackets. Plugged in the sub and hooked up sat speakers and it worked. I had it set up and working the same night I received it. Sound is good.

I love the Vizio Soundbar and it is a great home theater entertainment addition for the home. The only reason I gave four stars is beacause it sporadically disconnects from my television. It does not happen often, and this problem may be due to the fact that this is a refurbished soundbar. Other than this technical difficulty, it connects to mobile devices for music very easily, and sounds fantastic!
