Easy to setup, easy to use, great sound
This relatively low cost sound bar has remarkably good sound for such a low profile. Setup was easy. It came with HDMI and optical cables for attachment to the TV. I attached the HDMI to the ARC (Audio Return Channel) HDMI connection of my flat panel and just turned it on. The TV recognized the sound bar by turning off its internal speakers and playing sound through the sound bar. Additionally, it shows the audio level bar on-screen whenever the TV or sound bar remotes are used to adjust the audio level. I plugged in the wireless subwoofer and it connected automatically to the sound bar, but there is also a manual process if necessary.
It is also easy to use. There are various adjustments that can be made with the sound bar remote, but once these were made we only use the TV remote. The sound bar appears to go into sleep mode when the TV is off and comes back on when the TV is turned on. It is compatible with Dolby 2.1 content, but it cannot be upgraded with additional speakers.
There are five inconspicuous buttons on the top of the sound bar: on/off, source selection, Bluetooth on/off, volume down, and volume up. Bluetooth is used for playing sound from other sources like a smart phone. These buttons also appear on the sound bar remote along with other buttons for mode selections. There are three sound buttons: Movie, Night, and Music. We use the Movie mode mostly as it âexpandsâ the soft and loud sounds as if in a movie theater but with 2.1 speakers. The Night mode âcompressesâ the sound levels, making âquietsâ a little louder and âloudsâ a little lower. This mode is good for late night listening with the sound turned down so that others arenât disturbed by loud explosions and you can still hear the âquietâ portions. The final sound mode, Music, is for listening to music with the frequencies set at a more equal distribution.
There are also three buttons for Voice Adjustment. These adjust the voice frequencies to make voices easier to understand. At the highest level, number 3, we can tell that voices are much clearer but they sound somewhat unnatural. Consequently, we normally use level 1 and occasionally level 2 when necessary.
There are a series of lights on the front screen to indicate operation and when modes are selected. The main light comes on when the sound bar is in operation and goes off when it goes into sleep mode. This is a soft light and I do not notice it when watching the TV. The color changes whenever the Dolby 2.1 signal is received and being used. Other lights on the front will turn on momentarily whenever a new mode or source is selected to indicate that the signal has been received and the change made. There is also a light that comes on when Bluetooth is turned on. This goes off when Bluetooth is turned off or when Bluetooth goes into sleep mode if it is not in use for more than 15 minutes. Note, the auto sleep mode is not the default and this option has to be manually selected to be in use.
This sound bar produces much better sound than the TV speakers and requires little attention once the adjustments are set; we mostly use the TV remote. My only criticism regards adjusting the subwoofer levels. The subwoofer has bass minus and plus adjustment buttons on the remote but, unlike the other mode adjustments, there is no visual indication that anything is happening when this is used. There isnât even an indicator that it is wirelessly linked except for the lights used when manually connecting it. The bass can be adjusted up to the point that deep voices and drums rattle items on the shelves in the room. When adjusted down to reduce such rattles we have no way of knowing if we are at a mid or lowest level. The bass can be adjusted to what is being listened to, but it would be nice to know the actual setting so that a âstandardizedâ level could be selected for particular circumstances.

Plug & play with stellar sound.
I recently upgraded to this system after moving from a REALLY old 5.1 virtual surround Sony amplifier/soundbar.
It’s my first experience with DTS:X/Atmos and I’m impressed for the cost. Probably the most stand out feature by far is the voice amplifier; we’ve all played shows/movies where the vocals are either too soft or too loud, this always makes voices crystal clear even in quieter movies or action packed scenes with movies; I’d always have to play with subtitles, especially older titles as you’d often have to increase the audio to hear anything. This feature does a great job of amplifying vocals without blowing up the other audio.
It’s also truly plug and play. While there’s no EQ adjustment, it sounded great out of the box. I personally just increased the bass a bit.
Now on to Atmos/Virtual DTS. Compared to my decade old Dolby audio soundbar, it does an admirable job “virtualizing” sound from left/right/above you. Is it going to perform as well as a true 3.1.2 system with dedicated speakers? No! However for a bedroom or something it’s just about perfect.
It has simple indicators that tell you if something is playing through Dolby/DTS (green) Atmos (cyan) and stereo. (blue) Depending on your source (Netflix, or supported show, it will adjust automatically to the highest available output)
It’s a shame the virtual technology hasn’t really improved that much from a decade ago, but really you’re never going to get that “true” surround sound experience without multiple speakers.
For smaller spaces, apartments, etc, it’s going to perform very well. For large entertainment rooms, you’d be better off with true multi speaker setups.
With that said it’s very loud. I keep it around 20/100 for a master bedroom. I could see it filling a larger space very easily if needed. It also “upscales” most stereo sound from older movies/shows to Dolby which is a nice touch. (Although not a novel feature, basically just levels the audio)
Polk always delivers high quality audio, just don’t expect a true “theater” experience with just a soundbar and subwoofer.

Muy bien audio. Se escucha perfecto las voces y en general el volumen es alto. Los bajos son secos y no tan profundos pero era lo que buscaba, mejor que algunos modelos Bose.

I bought the S4 set after a lot of analysis. At this price point, it’s the best on offer. The sound quality is simply amazing. The top-firing main speakers are rich, deep, and clear, and the sub kicks in at all the right moments. The system especially shines with our HD Blu-Ray system. I have zero regrets about this purchase. Polk isn’t an electronics company with a speaker division, it’s a speaker company that makes outstanding speakers.
To the other reviewer who says this sounds like TV speakers – what?? I used a basic HDMI cable from the eARC output on my TV to the speaker bar and have had no problems; this ensures the volume can be controlled using the remotes for any device: TV, Blu Ray, whatever. You can adjust the Polk’s preset equalizer settings and/or adjust the bass/treble using the included Polk remote control. There is simply no comparison to be made between a TV’s embedded speakers and this soundbar system.

La calidad de sonido de este sistema es muy buena y es muy sencilla la instalación, solo se conectan los cables de alimentación, el cable HDMI, el cable óptico y listo. El control remoto es muy fácil de utilizar, solo con oprimir un botón activas el sonido tanto para modo cine, música o nocturno. Sin duda es un equipo de sonido que vale la pena, siendo una barra delgada y el subwoofer (inalámbrico) pequeño, brindan un sonido claro y de bajos potentes.
