## Questions & Answers

**Q: How's the sound quality without adding a subwoofer?**
A: I have it hooked up to a subwoofer but I usually only turn it on for music. Although there certainly is no true deep base from this sound bar without a sub woofer, I think that many users will find the amount and depth of sound from this pleasing as is.  Keep in mind, there is a reason that high end sound bars start hundreds of dollars more than this costs.  What you are getting with the Vizio SB2920-C6 is a vastly more pleasing audio than what the standard LED tv speakers can provide, and it performs well as that, but it is not to be mistaken for "audiophile" quality.

**Q: I want to hook the sound bar up to a Samsung 50" TV. I see that the Optical cable is frequently purchased with this. Do I need one?**
A: You do not need the Optical Cable.  I would suggest purchasing a Samsung Sound Bar.  I have a Vizio TV Set and it works absolutely fine.  I did not use the Optical Cable because the TV is hooked up to Optimum Cablevision.    You have to program the remote to your TV set.  It comes with a manual showing you how to do it.  I.  This is something you need to decide on.. I would contact  Samsung and see if it is alright.  Samsung is A very good product.  Vizio does not have the quality of Samsung..

**Q: Does this have a Ac power cord or just the batteries?**
A: Ac Powe cord

**Q: Can you use the tv remote to control the sound bar?**
A: It depends on the remote.  I'm using a comcast xr5 remote and it works to control tv and sound bar if programmed properly.   The xr2 remote and regular comcast remotes do not work with this sound bar.  The xr5 requires the xfinity X1 system and I was able to switch the xr2 remote that came with it for the xr5 for this purpose.   It took quite a bit of research to figure this out...good luck.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Such an improvement over TV speakers!
*by C***W on August 28, 2018*

This sound bar was bought to be used with my TCL 4 series. Like most all TVs the speakers were not very good, at all. I'm definitely not an audiophile, but I do like to enjoy decent audio when watching movies and shows. But I'm not willing to spend hundreds of dollars on a crazy 7.1 channel setup. I looked at a lot of brands that I'd never heard of but that seemed to have decent reviews. But with a $100 budget, many of the choices were ugly to me. I like the look of the vizio sound bars. The reason I chose this model of the smaller $75ish 32 inch vizio, is because this model had DTS AND Dolby(the cheaper one only had DTS). This one also has 2.75" speaker drivers compared to 2.5". I honestly don't know how much of a difference any of that really makes, but I am really happy with my decision.I like that it comes with all the audio cables needed for the different inputs. I'm using optical, but it's nice to have the coaxial and 3.5mm to RCA cable if needed later.No support for HDMI ARC, but honestly if you need that option you'd probably be buying a more expensive option anyway. It does support Bluetooth if you want to stream audio from your mobile device.There are buttons on top of the sound bar for basic control, the included remote is needed for things like turning on and off the surround option and adjusting the bass/treble. There is a line of white LEDs down the left side of the front. This is just for basic feedback to tell you what the volume level is and for displaying what input you're using. Some people have complained about this and said that it's confusing. I found it to be simple and easy to understand.The sound quality is really a step up from a normal TV. I was really impressed, and I think most people would be happy with it for $100. There is an output for a subwoofer if you want to add one. I think that it has enough bass for most people, but I'm glad there is that option. I don't think you can do much better for the price. I've been using mine almost daily for 2 months with zero performance issues. No rattling or defects, so far.Update: almost 3 full years later, this thing is still working as good as the first day I got it!

### ⭐⭐⭐⭐⭐ For the price, can't be beat.
*by S***D on August 17, 2015*

DESIGN: A+The bar has very simplistic styling with a column of LEDs that light up to tell you different things, like the volume level, when it's searching for input devices, etc. The fabric lining on the speaker occasionally needs to be dusted. The remote is very easy to use and comfortable to hold.SOUND: B+If all you want is an improvement over your TV speakers, you are definitely gonna get it. I am not an audiophile (though I do have numerous pairs of decent headphones) but I can say that the sound is good. Not surround system and home-theater good, but good. Dialogue in TV shows (those epic drama ones in which everyone seems to be whispering for some reason) is finally listenable! That was the biggest thing for me. This is especially true if you use the TruSurround and TruVolume features, which I will get to...Music plays well, but if you have a good pair of bluetooth speakers, you can definitely see the disparity in sound quality. This is most likely since this sound bar is meant for mainly TV use.FEATURES: A+Using Bluetooth to connect to your phones, tablets, computers, etc. is easy and can be done with the remote. There are two buttons on the remote, for TruSurround and TruVolume.TruSurround simulates a surround sound experience. Unsure how to explain this, but the sound seems "more spread apart" in terms of the lows, mids, and highs. The bass is great in this mode. If you sit close enough to the sound bar, it actually does feel like you're sitting in a surround sound experience. For me, though, there was a bit too much distortion in some dialogue with this feature on. If I am watching a movie (which is when you'd want this on!) unfortunately I'll turn this feature off. Music sounds good with this feature on.TruVolume normalizes the volume level so the really loud and really soft noises aren't as far apart in volume level. This is a REALLY GOOD feature for movies and shows in which the dialogue is difficult to hear! I recommend turning this feature off if you're listening to music.If you want, you can go into settings and change the individual sound settings, just as you would with a car stereo or any other speaker system.PRICE: A+. Home run.For $100, this purchase was a no-brainer for me. After years of missing out on distorted TV-speaker dialogue, turning this speaker on felt like wearing glasses for the first time :-)
