  • A. The product description is technically lacking - doesn't even state what type(s) on interfaces it supports or what type of "audio cable" is included...nor the output wattage. I think the dB numebrs are the standard efficiency numbers, but maybe they are the full volume numebrs...regardles, the wattage should be listed. Finally noticed the link to the data sheet. It says there is a sub output, and multiple inputs - analog and digital. If there is not a sub output, I think the signal from the TV could be split and sent it to the soundbar and a subwoofer in parallel. Or use digital connection for the sound bar and an analog connection to the subwoofer (if the TV has analog output, LG's don't anymore, for example. Lastly, I've even seen digital splitters (amazon - cheap), but they are flakey (reduce the signal too much for some people's equipment).

  • A. Thank you for inquiring about our product. This sound bar does not have a port for a sub woofer. It does have powerful audio performance with SRS TruSurround HD™ and SRS TruVolume™ technology making the need for a sub not necessary. Thanks again and have a great day.

Customer has been confirmed to have purchased the item from Walmart.

This is the 2nd Vizio Sound Bar I have purchased from Walmart.Com. The first was a model 207 32" sound bar which far exceeds my expectations. The latest sound bar is the 40" model and just like the first bar, this one exceeds my expectations. The only thing I might have changed would be to get the same model with wireless subwoofer. The bar is great by itself and installed in less than 5 minutes. For some reason the included hook up wires were faulty but I always keep RC stereo jacks in the house so I used them instead and it works perfectly. For those who don't know what I mean the RC jacks are the common red and white wires used to hook up external devices like cd player, turn table, speakers etc. Just use red and white to back of tv out and the other end into red and white on sound bar and presto,,, great sound. As I said less than 5 minutes. Ability to control volume, sts sound is a huge plus on the vizio remote. Great product for the price.

All I can say is OMG !!!! I just got the Vizio sound bar and hook it up to my Vizio 55" TV and it sounds better than going to the theater. It is going to end up hook up to my 65" 3D Vizio TV and I can't wait. I have it hook up with the red/white auto cable, but I think I will get a Digital Optical Auto Cable. All I can say it is a great sound bar, and I would highly recommend it to everyone. Once you hook it up and turn it on you will say thank you for helping me pick out a great sound bar.

I have never used a sound bar and I love this one. It sounds like a stero. I had no trouble at all hooking it up to my 42" flat screen. It was worth the money.

The sound is incredible, and it was simple to hook up. There is one thing though, my 42 inch Vizio TV is not mounted on a wall and it sits very low on the TV stand. So, the sound bar blocks the remote sensor on the TV making it a pain when you want to adjust the volume or turn the TV off. I had to raise the TV up about 2 inches by putting a board under it. So, if this might be a problem for you, measure the space from the bottom of your TV to the top of the TV stand/entertainment center. The sound bar is slightly over 3 inches high. My TV is less than 2 inches up from the top of the TV stand. That's the only reason I didn't give it 5 stars.

Customer has been confirmed to have purchased the item from Walmart.

I just returned this soundbar today. Sounded great on tv shows. I was very disappointed when I tried watching an action blu ray movie. The soundbar would have distortion on action scenes. Even at low volumes it would still distort out. Leaving me to turn the volume up and down constantly through the movie. I thought it may have been the movie I was watching but I tried several other Blu rays over the past couple of weeks and they still have the same problem.

Not labeled for cord to fit TV!!

I read thru the manual and for five days I have tried to reset everything from TV to cords, etc. I may be 70 years old but I do read------WHERE do you state this is not a "digital" cord??? I have talked to Vizio and am told I need to go out and buy this digital cord. What isn't digital nowadays. Your setup page on #1 setup does not point out this cord difference either. On the help page you talk about cords but do not talk about "RCA" cord vs. Digital! I live 100 miles from the shopping center closest to me. This is why I bought a name product and ordered delivery! Have I been mislead or didn't I read that perhaps I might need a different cord. You only say to connect "the included Stereo Cable to a T V audio output as shown." In small print you say not all TV's have the audio outputs as shown. .?? My Sharp TV looks exactly as shown. I have read the reviews and everyone says how EASY it is!! Don't believe it. I am sending this back!!!

I bought this sound bar for a Christmas gift for my dad his T.V. does not produce the best of sound being the T.V. speakers are located in the back part of the T.V. Ever since hooking it up which was very easy he has been happy with it. We had 4 main areas for our selection which are Overall sound quality of the speaker, price, connecting, and style all have met our expectations.

This sound bar produces fantastic, quality sound. Set up is a snap, if you make sure to read the accompanying pamphlet. Highly recommend this if you are listening to your televison with the tv speakers only...I had no idea how much of my movies I was missing without quality sound!

This was given to me from my wife for a Christmas present. It provides the extra uNF! that the TV speakers on our Panaonic Viera couldn't. There is absolutely nothing wrong with these and would recommend to anyone looking for an improvement in TV view without breaking the bank. Well worth it!

Customer has been confirmed to have purchased the item from Walmart.

This is a good sound bar with the composite cables that was included with the purchase. But, a great sound bar if you purchase a optical digital cable instead! The only negitive is the remote control. Its distance and angle ability seem limited.
