Missing surround sound
The soundbar marketplace is deceptive. It doesn't matter how good your features are or how great your sound is. If there's something better for the same price, you'll be the odd bar.
That's the tough lesson Polk Audio's new $ 250 Signa S3 sound bar system is learning. It's a solid option on its own as it's a Wi-Fi enabled soundbar with effective two-channel sound, but Polk just forgot about the budget monster waiting in the opposite corner of the ring. If you don't know who we are talking about, you are close to it.
design
At various times in the past, both myself and my staff at Digital Trends have praised the soundbars that can be heard but not seen. That said, the bars that feature a design that doesn't protrude and blend in so well with the room that you won't know it's there if it's not emitting sound to you – the Bose Soundbar 700 is here one good example of success.

Soundbars from Vizio, LG, Samsung and the like have done this to one degree or another in the past. And I'd argue that the Polk Signa S3 probably fits that category too, and I like the aesthetics of this particular soundbar more than, say, the Vizio counterpart. One notable point is that the color and shape of this bar appear less harsh in comparison. The Vizio V-series is a black, brick-shaped bar with a slightly less black grille. The polk looks softer and tastier with a lighter, grayer grille that plays off the otherwise black bar well. This color is paired with a more rounded shape without all of the sharp edges, which I liked too.
The Signa S3 is a little over two inches tall and around 35 inches wide, which fits closely with competitors like the Vizio V series. There are two pairs of tweeters and mid-range speakers in the 2.1 channel strip. For comparison purposes, the Vizio has a dedicated driver for the center channel of its 5.1 configuration. One driver doesn't seem like much of a difference, but as we'll see in a moment, that particular driver is a crucial one.
The wireless subwoofer for the Signa S3 is front-ported and follows the footprint of soundbar woofers such as the LG SN7Y. They're so similar in size, in fact, that it took my significant other a week to release the submarine in the corner of the room. It was different from the week before. That gave me my first concerns, as the subwoofer for the SN7Y did not impress me with its performance. More on that in a moment.
The remote control for the Signa S3 feels a bit cheap, but is conveniently located on the smaller side and is easy to hold. The Signa S3 supports Polk's AnyRemote technology, which means it should automatically respond to IR signals from most TVs it is connected to. According to Polk's website, the Signa S3 works seamlessly with Samsung, LG, Vizio, TCL, and Sony TV remote controls for volume control, as well as most CEC-enabled TVs.

The Signa S3 has a book report size quick start guide that includes it. I strongly recommend that you do your homework. Take it from someone who has been too persistent to read manuals for years: if you put pride aside and let the included documentation guide you through setting up the soundbar, things just get infinitely easier.

It starts like any typical soundbar: plug your soundbar into your TV, plug both the bar and subwoofer into power, plug the included AAA battery into your remote, and turn everything on. The subwoofer should automatically connect to the bar and the entire system should be ready for playback in a matter of moments.
Unlike some competitive bars where the input that the soundbar is plugged into is literally written for you, the Signa S3 tells you this via a horizontal row of LED lights.
It all went smoothly for me, but the next few steps gave me a break. Unlike some competitive bars where the input that the soundbar is plugged into is literally written for you – the LG SN7Y mentioned above comes to mind – the Signa S3 tells you this via a horizontal row of LED lights. Some make sense (a single blue light indicates the bar is in bluetooth mode), but beyond that it gets confusing. Fortunately, it is broken down for you in the quick start guide and acts as a translator for the foreign language of lights the S3 is talking to you.
The guide also directs you to the Google Home app, which you can use to connect the Signa S3 to Wi-Fi. This is a very simple process. It's a smooth transition from the tutorial to the Home app as the app walks you step-by-step through adding your network and tweaking your bar. I didn't have the resources to try at the time, but I'm confident that a far less tech-savvy person can get this system fully up and running in 15 minutes. In my opinion, that's the hallmark of a good, easy-to-use soundbar.

Even by soundbar standards, the Signa S3 keeps things limited when it comes to connections. There is a single HDMI ARC port, a digital optical port, and an AUX input. For context, the Vizio V-Series adds a 3.5mm stereo audio input as well as a USB port to the mix. I recorded before saying that most soundbars need additional connections, and I stand by that. But that's a soundbar on a budget of $ 250, after all. More HDMI ports would have been great, but at the price, it's not a deal-breaker.

This is where the Signa S3 gets a great value at least in terms of connections in my opinion. Unlike much more expensive bars like the LG SN7Y and Sony HT-G700, this Polk Bar has built-in Wi-Fi. This is huge for my money as it opens up a world of possibilities. For this reason, Google Chromecast is built into the bar, with options for streaming Google Play Music, Spotify, and many other services right into the bar. Plus, you can control your music with a device equipped with the Google Assistant, and group your soundbar with other Chromecast-enabled speakers to create whole-house sound. In addition, your soundbar may receive automatic software updates to keep the product better over time.

The Signa S3 also has a Bluetooth connection. But with the option to stream Wi-Fi and enjoy sound with no dropouts or disconnections, I don't know why you would ever choose the former over the latter. By equipping their bar with Wi-Fi, Polk has not only done what all soundbars – including the competing Vizio V series – should do, but also what we believe there should be no excuse not to do so in 2020 .
Sound quality
This is the make-or-break category for the Signa S3. For some, the stereo sound produced is comfortable enough and well worth the price of admission. But for others hoping for an even more immersive experience with their soundbar, they will likely want to look elsewhere.

The thing is, this is really not a controversial – or even controversial – statement. Finally, the Signa S3 is a 2.1-channel soundbar. It will work better with audio that is meant to be heard in stereo (i.e. music) and worse with content that benefits from a surround sound setup (most TV shows and movies). Polk gets a little sneaky when he says it supports the Dolby Digital 5.1 sound format, which it technically does. It simply cannot be reproduced as it is again only a two-channel bar. Not all support is the same here, so the language is irritatingly misleading.
For the music, I found this bar to be excellent. Polk is a company that has made a name for itself in the audio space, unlike the bigger brands like Vizio, Samsung and LG. The company has made music-friendly speakers in the past so it came as no surprise to me that the bar can wonderfully clearly reproduce tracks like Mumford & Sons' Lover of the Light. As for the bass, the S3's compact woofer has handled short, punchy deep tones effectively. However, when the sub was asked to go deeper, or when the bass was increased using the beam's remote control, it succumbed to the limitations of its size and unfortunately sounded like it was stretching for a frequency it just couldn't quite reach . If you're not asking too much, you'll be happy with this subwoofer – you just have to know what it can and can't do.
If you try to squeeze five (or more) channels into two the result just won't turn out what it's supposed to.
I want to be as clear as possible with this soundbar when it comes to watching movies or TV shows: objectively speaking, this is an instant and significant improvement over standard TV speakers and brings you the way this content is meant to be heard , far closer. The clarity I mentioned when discussing music is still there, and the sub adds a modest rumble to your listening experience.
But for the third time, and probably not the last, it's a numbers game. If you try to squeeze five (or more) channels into two the result just won't turn out what it's supposed to. In that regard, I'll be taking advantage of the Vizio V-series 5.1 setup or the impact Dolby Atmos had on the LG SN7Y's 3.1.2 configuration, albeit at a significantly higher price. Maybe I'm just too used to having noises above or behind me, but my selection of tests (Mad Max: Fury Road, John Wick, A Quiet Place) just weren't the same audio glasses I was supposed to be getting be on the Signa S3.
The Signa S3 has three sound modes that you can use to customize your audio: The Movie mode "improves audio playback in TVs and movies," Polk said. Night mode attenuates bass and dynamic sounds to keep the neighbors at bay. and music mode is good for music. These all work in that they are the best preset for any situation, but don't expect them to be breakthrough modes that will change the way you play audio dramatically. The same goes for Polk's speech adaptation feature, which allows you to switch between three different levels of speech enhancement. It's helpful, but not as helpful as having a dedicated center channel.
Our opinion
The Polk Signa S3 is a 2.1 channel soundbar that does exactly what it was designed to do. That said, the bar picks up the provided audio and creates a fun listening experience that is exponentially better than anything standard TV speakers could produce. The problem is that its value is being damaged by competitors bringing more to the table without much of a drag on cost. A year ago, having surround sound at that price might not have been that important. But the bar (no pun intended) has been raised and it overshadows an otherwise good system.
Is there a better alternative?
The $ 250 Vizio V series gives you a 5.1 experience for the same price, which makes it a better option for a movie night, though I would still prefer the Signa S3's sound for stereo music. The $ 350 Yamaha YAS-209 is a more advanced alternative to the Polk. Amazon Alexa is integrated into the bar and compatible with DTS: Virtual X. However, like the Signa S3, it does not have true surround sound.
How long it will take?
Polk has a two year warranty on this pole which is also a well made product. With the bonus of software updates, this bar should be able to be a fixture under your television.
Should you buy it
I think it depends on your use case. The Polk Audio Signa S3 has a lot going for it, including built-in WiFi and exceptional stereo sound. If your plan is to not only use a soundbar for movies but also get a healthy dose of music on the go, I would have no hesitation in suggesting the Signa S3. But I think most people value surround sound over streaming music, which makes the Vizio V series a better option for the average consumer. In other words, Vizio, the king of values, wins through a difficult decision.
