Customer Ratings & Reviews

Overall decent product .. sound cuts out briefly on some programs and also cuts out on every volume adjustment. Sound is good though

The sound is good but it doesn’t have a before subwoofer. I had to return and get something with more rumble

This soundbar and wireless subwoofer sound terrific, have great features, and are easy to set up. There is no app required that has to be downloaded for setup or control- it's straight forward plug and play, with features controlled by its remote control, and on/off and volume also controlled by the TV remote. Features include bass control, Movie, Music, and Night modes, and voice enhancement. The Doly Atmos sound is amazing when playing movies or music produced with Dolby Atmos. There's great depth and clarity - you truly get immersed in sound. The movies are the best, I felt like I was actually in the theater with rumbling bass and surround sound. Too bad not all movies have Dolby Atmos and most music does not. The newer music originally produced with Dolby Atmos sounds better to me than older music remastered with Dolby Atmos. The music service I stream with has playlists that include both originally produced Dolby Atmos songs and older songs remastered to add Dolby Atmos and I could immediately tell the difference. The modes make a difference, watch movies in the movie mode, and listen to music in the music mode. They work great- each brings out what you want in movies or music, rumbling surround sound and depth and clarity. The voice mode works well for movies or TV when you need voice enhancement to understand the dialog. Bottom line is this soundbar and subwoofer are well worth the price. I've had more expensive ones that don't come close to matching the sound of this Polk Signa S4. I don't think anyone who buys this would be disappointed.

Excellent quality and sound for the price! Would definitely purchase

Sounds great, Atmos lacks a bit bit for the price it’s fine. I returned a Sony and a Vizio before I settled on this Polk

The real deal with this one, you can hear every detail in a movie!

Great sound bar at a nice price. Nice Atmos surround sound.

It did not take long at all to set up this soundbar.

Over priced for same quality as something half the price.

Wow, this Signa S4 ultra slim tv sound bar with wireless subwoofer is really great. It's not too big and fits perfectly near the 60-inch tv. It also looks nice and fits very well with other items in our entertainment area. The size gives a lot of flexibility in where to put it and is easy to move. We moved it a few times, to find just the right fit. The sound is smooth and clear. The subwoofer works great and you can feel it all around the room. The fact that it is wireless is very convenient. Thev whole set really gives the experience of a theater right in your living room even with our open-floor living room and dining room combination. The setup was simple and easy, it was pretty much just plug and play with the HDMI cable and quick set-up. The remote is easy to use and simply labeled. The music mode works very well too. It is also very easy to connect to Bluetooth. We are impressed that even though it's slim, it works great and the quality of the subwoofer and soundbar is awesome! I would definitely recommend this. This is a game changer for movie night in our home.

The separation is lacking and the bass has no midrange.

Sound bar design is good. Surround sound seems to be good.

A little over 1 year later the soundbar does not power on. I have always owned Polk audio equipment and am very disappointed.

Awesome sound quality and setup process is extremely easy compare to other products.

Great product. Super easy hook-up. So easy even a caveman can do it.

Great soundbar but finer controls over EQ would be nice. Currently using this in my bedroom attached to my Samsung QN90 and the eARC works flawlessly. I really appreciate only needing to use my main TV remote for daily usage. I would like to see a on screen user interface and finer audio adjustments but you can get by using the dedicated remote for basic adjustments. The sound quality is great and easily fills the bedroom. The sound field definitely sounds wider than the width of the soundbar and gives the illusion of discrete front speakers. In the bedroom the surround effect is a little lost being positioned so far away from the soundbar but when sitting on the edge of the bed closer to the TV it is definitely apparent. ATMOS also has a much better effect when seated closer to the soundbar as you would be in most scenarios. The sub provides enough bass for an 18x20 room and fills in where the bar falls off. If you are looking for an upgrade to your TV speakers and want clearer vocals without adding tons of volume this bar is a solid choice!

Not working prpperly. Been waiting 5 weeks for them ti come back out and fix or return

Atmos for the masses has arrived with Polk's Signa 4 soundbar. It is big enough to provide impressive sound, costs less than most other Dolby Atmos soundbar systems and has the easiest setup of any soundbar I have ever used. Of course the big plus with the Signa 4 is you get real Dolby Atmos sound, thanks to 4-front and 2-up-firing speakers as well as a small, center channel speaker in the slim, cloth-covered soundbar. Bass is provided by an outboard but compact wireless subwoofer. This setup, which uses some special Dolby sonic tricks, creates the illusion of a tall wall of sound in front of you and a bit of a wrap-around effect, for a limited immersive feel. It's a long way from the massive Dolby Atmos setups in theaters, which have way more power and a lot more speakers spread out all around you. But given the small package, the Signa 4 does a pretty amazing job, for not a lot of money. My biggest beef is with the tiny 5.25-inch subwoofer, which does not have the size or power to produce those big thumps and booms you can feel in your gut -- a common feature in many big action movies with Atmos soundtracks. . But the Signa 4 system does provide enough bass to balance out high- and mid-range speakers in the soundbar. In fact, the overall balance is quite good in most cases, resulting in a rich, natural full-bodied sound. Voices are particularly strong, which is great news since that is often a major weakness in many other soundbars. In some movies, the dialogue often gets drowned out by all the music and sound effects during busy action sequences. I got the opposite result with the Signa 4, with music and sound effects sometimes greatly dialed back compared to other home theater sound systems I have used. Part of the reason for this may be that my TV only supports ARC instead of the newer eARC standard, which sends the full incompressed Atmos soundtrack from the TV to the soundbar. ARC has less bandwidth and therefore compresses the signal, producing a flatter, less dynamic sound. TVs with eARC are becoming more widely available now but if you have one more than a year or two old, you are probably stuck with ARC and its inherent limitations. There is no upgrade path short of buying a new TV. You need at least an ARC HDMI connection between the soundbar and TV to get Atmos. (An HDMI cable is included) The Signa 4 also supports an optical connection (and even Aux) if that is all you have, but Atmos is not supported over optical or AUX. (An optical cable also in included.) By defalt, the Signa 4 upmixes all sound to simulated Atmos, regardless of the source or encoding. This is a good thing since it makes it seem as if you are sitting in front of a wall of speakers instead of just a little soundbar, even if you are just watching the news or TV show. There are no side or rear speakers in this package and no option to add them later. As a result, you don't get the precise, positional sound movements those extra speakers make possible. The Signa 4 attempts to simulate that wrap aound effect using sonic tricks built into Atmos, and it does work to some degree. But it is not as clean as having discrete speakers to handle those chores. Unlike some earlier Polk soundbars, the Signa 4 has no HDMI inputs beyond the one for ARC. So if you have a game system or Blu-ray player, they must be run directly to the TV, which will then send the sound to the soundbar via ARC or eARC. That's a little disappointing since a direct HDMI connetion from those devices would give you same uncompressed sound you get via an eARC connection. Technophobes will be happy to hear the Signa 4 is extremely simple to set up. There are no apps, no forced registration with name and password, and no wi-fi connection to worry about. Just plug in the subwoofer. Plug in the soundbar. Attach the HDMI cable to your TV and you are ready to go. The remote is dead simple too, an improvement over the ones that came with earlier Polk soundbars. There are controls for volume and bass, three different sound settings (movie, night and music) and three voice modes. High contrast markings make everything easy to see. But you may not need to use it much since the Signa 4 is compatible with most TV remotes ( and some streaming devices) right out of the box. No remote control juggling required, unless you need to adjust a special settings on the Signa 4. Bluetooth also is supported, if you want to use the soundbar to listen music from your phone or tablet. I was less impressed with the sound quality on that front, which seem somewhat flat. Although there is a dedicated MUSIC sound mode, I found the MOVIE mode (which produces a wider and taller sound field) sounded better. One other minor complaint: There is no dedicated display on the soundbar to indicate what mode you are in, or much of anything else that is going on. As with most previous Polk Soundbars, there is just a row of little round lights that briefly illuminate when changing volume, bass settings. Some also blink or change color when you mute sound, pair bluetooth or do other things. Not very intuitive. Still, it's good system overall for those who have been hankering to upgrade to Atmos but did not want the spend the kind money most Atmos soundbar systems still command. Just be aware you need to have a TV that supports eARC to get the best sound, and bang for the buck.

I have this set up in a small bedroom that is about 80-100 square feet. Not only does this sound bar cover the entirety of the room with excellent sound, it is audible from anywhere in the house. The bass really kicks when you're watching action movies or there is a soundtrack with a lot of bass. You are able to select what type of sound you want your system to focus on with this soundbar. If you want to hear the vocals more, there are buttons for that. You can select from 3 different ranges of voice enhancement which all increase voice output sound and decrease everything else in the sound signature. You can do the same with the wireless bass. You are really able to control how you want your movie, tv show, or music to sound. I like having the vocals at the forefront when watching most movies especially when there is a lot of action since I don't want the voices drowned out. The difference between the default setting and enhanced vocals is crystal clear. The sound bar has Dolby Atmos enabled speakers which do make a difference when watching a movie but it isn't ever going to be like having an Atmos speaker above you. It is good enough to enjoy those movie moments when something whizzes over your head but not perfect. Overall, this Polk soundbar is awesome for the bedroom. I'm sure it would work in a living room as well since the sound really travels well.

I am completely impressed by this sound bar. I only have ARC, not eARC which apparently is required to get true atmos signal but it still sounds fantastic. I temporarily put this in place of my 7.1 system which starts with klipsch 6.5” center and 6.5” bookshelf fronts and a 12” klipsch sub. While it doesn’t blow it away, it sounds fantastic in comparison. The soundstage is very impressive and if you were looking at the setup you would honestly think it was the big speakers playing. Also the voice settings work well to enhance the dialog if you are trying to watch at lower volumes. Bluetooth connects easily every time and the range is excellent! Cons: I wish it had an HDMI input since you lose one connecting to ARC or eARC
