Style Name: New Sound BarSize Name: 42-Inch
I can't add or refute praise buyers have posted for this soundbar system's audio fidelity and quality. After all, it was picked by CNET to receive the 'Best Product of CES' award at this year's Las Vegas "Consumer Electronic Show". I've waited since January to buy it, and finally, it became available locally at one of the discount box stores near me.

But, I can tell you, the unit I purchased was not ready for prime time, as several others have pointed out in their reviews. Recent reviews give me more hope. One reviewer said, "..the first unit I had would go silent when changing channels while using cable. Probably due to audio format changes between hd and regular channels but not sure. I would then have to turn the sound bar off then back on to get sound.", he said.

Folks, that was an understatement. After a pretty easy set up and using only the optical cable link from my optical output of my large flat screen Samsung to the soundbar, I immediately heard a dramatic difference in sound quality when compared with my older Vizio 2.1 system that had performed well despite it's inherent limits.

Then, using my whole system Logitech remote, I switched from a live cable program source in HDMI 1 to my Blu-Ray device. So far, so good. That is until I skipped DVD chapters or fast-forwarded the DVD. The audio dropped out and would not return unless I rotated through the various inputs to re-initialize the audio in the "optical" input on the Vizio remote. No amount of tries or even DVD changes would prevent this. Next, I tried switching to the HDMI input for the Roku streaming device, but any fast-fowarding of video of a movie in progress suffered the same audio loss, no matter if I used Amazon Prime content or Netflix.

Style Name: New Sound BarSize Name: 42-Inch
If you'd asked me a couple years ago which 5.1 sound system to buy, my answer would have been simple: "none."

They were a big expensive pain. It seemed like my friends who had these systems would either have them only half set up (say, ditching the surround speakers) or fully set up but not used (because the input selection or the remote was too much of a pain). My previous roommate had a 5.1 "surround" system - with all five speakers under the TV. We rarely used it because we had to change 3 settings in 3 different places to make it work.

Let's review the misery of yesterday's 5.1 systems, shall we?

1) You needed to place and wire six speakers: left, center, right, left surround, right surround, plus a bass module. That's a lot of wires, speaker stands, and connections.
2) To connect the left and right surround speakers, you needed to run wires across your seating area. That's pretty ugly unless you go through the effort to make conduits or buy a special rug.
3) You needed to purchase a separate receiver to power those speakers - and connect it too.
4) You paid for all that - an absolute minimum of $400, with nicer gear easily double that.
5) You needed to manage additional remotes and settings. Good luck if you ever asked a friend to change the volume.

Well, it's almost as though Vizio started with this list, and then eliminated these problems one by one when making this 5.1 soundbar. The soundbar itself combines Left, Center and Right channels into one thin module that will fit in front of your TV, assuming you use a TV stand with at least two inches of space there. There are no speaker stands or speaker wires, and no separate receiver - the amplifier is built in!

I got this directly through the Vizio website when it finally came out and have very much enjoyed it.

Pros:
- Looks great, feels substantial.
- Great remote. You can see what you are doing in your hand, instead of squinting over to the unit. Why don't all companies do this?
- Sounds very good for a soundbar (better than my previous Samsung)
- Rear Speakers, yay! They make a big difference for movies. In music they quietly play along in stereo, which is nice.
- Easy to use! I can't stand complicated controls, these are simple.
- Bluetooth works great. I use my iPhone, and whenever I turn on the soundbar it automatically takes over the music playing on my phone, like my car does.

Cons:
- Subwoofer level is hard to tweak. If it is set good for movies, it's too loud for music, and if it's set good for music, it's too low for movies.
- Subwoofer has to be in the back, with the rear speakers. I think it would sound better if it could come from the front.
- It's hard to tell if the unit is turned on. The tiny LED just shines a bit brighter.

I think this is about as good value for money as you can get right now in soundbar world. Any serious upgrade in sound quality would require a lot more money.

Style Name: New Sound BarSize Name: 42-Inch
I was extremely excited to finally get my hands on this system from Vizio. I did a good amount of research before deciding to purchase the Vizio S4251w-B4. I also had to wait a little while to purchase this unit because these things were in great demand the first few weeks or so. I have now tested the item for about 3 weeks and here is the breakdown:

After removing everything from the box I was initially pleased by the look and feel of the sound bar , subwoofer and accompanying components. They were solidly built and did not look or feel cheap. It took me about 30 minutes to set up because I chose to mount the sound bar above my TV with some brackets I purchased off of amazon. This set up turned out to be a great choice and adds a nice look to my overall setup.

Once the sound bar was mounted everything else was a breeze to set up. I powered everything up and I began to fiddle with the sound settings. I bought this system for my home office, which is 12 x 14 feet, so I figured it would be ideal for the size of the room. I basically went down the list adjusting each speaker and it took about 20 minutes to determine the best sound for my ears.

I put the system through the gauntlet. I hooked my Apple TV (optic cable) and HD DVR cable box (Coaxial) up to the sound bar. I played all sorts of music like rap, rock, and R&B and it handled each type very well. I will say that the subwoofer wasn't able too handle the higher frequency of the bass in certain music. I could hear the details in the music and the voice clarity was on point. I also cranked it up and the sound quality did not diminish. The sound was not harsh like it would be in lesser products. I also watched Life of Pi (great movie) to test the movie experience and that's when the Vizio really came to life.
