This Sound Bar Is Great ! ( Real Reviewer )
I just bought a Sony X93L with Dolby Atmos capability. Not a cheap TV. I knew I wanted a sound bar system for my living room that would do it justice. I looked & listened to sound systems by Sony, Bose, Sonos, Samsung, LG, Visio to name a few. Im a child of the 70s and grew up through the old school speakers with LOUD & LARGE surround sound home theater set ups. I love hearing all the small details around me. If i had unlimited cash I'd spent few grand on one of those systems. But i don't have that kind of money .... really I don't need that much sound system in my living room. I wanted a sound bar that would give separate bass and separation of some left and right and center channels and sound solid for movies, music and dialog. I didn't want a cheap sound either. When I listen to the brands i named before i honestly wanted to be impressed .... but just wasn't. It sounded good but many with a bar and sub together would be at least a $1000. Some much more. I came across this Polk Signa S4 and read the reviews. Polk has made solid sound for a long time. I took a chance and I'm glad i did. This sound bar is GREAT ! The build is very nice and solid. Remote is small and plastic but has very usable buttons especially the separate sound and bas volumes. Set up was fast, all needed cords included. It has very excellent center voice clarity. The other channels are distinct and create a wall of sound that "reaches out in to room before your TV and shifts left, right and up and down". It sounds really good and when your add the sub the bass flows in well but is also distinct and can be adjusted easily with the remote. If you want some bass rumble for those movies or thump for concert bass lines it can do it well. Is this system a full surround 7.1 plus sound experience? NO ! But you can really hear the shifts in channels reaching out in front of you from the array of speakers projection left, right, center and up. I personally found the bass in the front to the side of the bar by the TV is really good. But for me i placed the sub woofer behind me and got some really nice "surround like" feel that pulled all those sound bar channels all together to a more full room experience. Im totally satisfied and recommend this system. The price was $299 vs $1000 plus for some of the others. Amazon offered me a $200 gift card to sign up for their credit card making this sound bar cost $100. I was sold at $299 but at $100 it was a steal. Try it .... its a great living room system with Great value for the price. I Love It!

Great sound great value
Sound quality is fantastic, wanted a little more sound from my flat screen and this is perfect. Installation was very easy, literally plug and play. Soundbar has good clarity and sub has a good amount of punch. Im in an apartment so no need for crazy volume.

Nice With A 2020 LG TV
My first soundbar! This is definitely a big improvement in sound (volume, clarity and bass) over what were already pretty nice sounding built in television speakers which I listen to at about volume level 9 (of 100) for casual daily YouTube videos. I can bring it to level 13 when wanting to be more immersed in Netflix and such. I don’t need much volume in my home (though in my car I have a 12” subwoofer and play music at 75% volume LOL). VOLUME: The sound bar can get much louder and with that extra volume it stays more clear without being distorted unlike the built-in television speakers that start to sound distorted when it gets 50% and above in volume. REMOTE CONTROL: This soundbar CAN be controlled with my TVs remote so long as it’s connected not just with the optical audio cable but the HDMI cable as well going into an ARC HDMI port on the tv. The soundbar turns on when I turn on my tv and turns off when I turn off my tv. I don’t see a volume level on the soundbar which is my first complaint about the soundbar. It’s also not on my tv when using the soundbar. I just see a + or - on the tv when I press those buttons. EQ (ISSUE 1): Sadly there is no real EQ settings on this. There are several buttons on the REMOTE ONLY (not on the soundbar itself) that have 6 custom sound settings: Movie, Night, TV, voice 1, voice 2 and voice 3. I’m not sure if you can combine these. I switched to “night” and then “voice 3” thinking that maybe it would simply enhance the voice on night mode but when I press night mode again it resets the voice setting. So I think it’s either or. And as a 7th choice you have your bass volume. Thats the extent of EQ options. When using the built in speakers the TV had tons and tons of options with 5 frequency sliders (for sub bass, bass, mids, high mids and treble), surround sound, magic sound, add bass, add treble… so much. That’s all greyed out when using the optical audio out to this soundbar. I don’t know if all of those settings would still be there if I got an LG sound bar with my LG television. But considering I don’t know what brand of television will be my next, I couldn’t worry myself with matching the soundbar brand. So far, I guess it doesn’t matter that there aren’t as many EQ settings, the speaker sounds pretty good as is. I leave it on “Movie” for everything. I have my Apple Music hooked up on the television but haven’t used it for music yet, I presume I would want to put the soundbar on the music setting for that. ISSUE 2: I am not sure is an issue with the speaker or the television but when watching YouTube for example, if you are on the YouTube menu, there is no audio signal being sent to the speaker and thus you see single white dot of light. When you have clicked on a video and the audio signal is sent to the sound bar, the single white light turns green. The PROBLEM is that there is a fraction of a delay after the video has started before the sound starts on the speaker. There are many videos I watched that for some reason has someone speaking from the very first frame of video and the sound bar always misses it, the sound turning on 1-2 words late into the video. It has nothing to do with speaking specifically, whatever the sound is in the video, the speaker doesn’t activate until a fraction of a second after the video starts. It’s a bit jarring, and a little more annoying. If I rewind the video to the beginning I’m just repeating the situation because rewinding means there is no audio signal going to the speaker and so I see the white dot again, that once again doesn’t turn green until a fraction of a second after the video starts again. But aside from those issues, it really does sound good and I haven’t felt a need to crank up the base much because it sounds pretty full as is, without sounding too bassy or muffled. I experimented with the voice enhancement buttons. I’ve settled on “voice 2” to bring just a little bit more clarity and audibility to the voices when I have the volume a bit lower so as not to disturb others. It sounds good, I can make it louder than ever before if I want. I can control its volume and on/off without needing its remote (though I need its remote for the other EQ settings). I got it “open box” but it looked brand new I must say for $143.80 which is a good price for what this is. And I trust the Polk brand.

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.

I basically bought this for watching BBC nature documentaries since my TV's inbuilt speaker had hard time delivering clear dialogues but I think this Signa S2 is overkill for that purpose. I should have gone for Signa Solo which was selling for 8k during sale (including bank discounts). Now coming to it's capabilities. FORMAT IT PLAYED : Dolby digital, Dolby digital plus, DTS, DTS-HD (Master Audio) and many other formats except Dolby TrueHD & Atmos where TV displayed something like "audio not supported in this video". My biggest concern was if it can play DTS files and it plays them brilliantly. I felt DTS sounded better than Dolby but it may be due to higher bitrate of dts files. VOCALS are amazing. Super clear. Actually whole sound speactrum is too clear with great instrument separation that you will be able to distinguish between different sounds/instruments being played. High notes tone (Tweeters) are just pleasant to listen to. Polk's Voice adjust feature is extremely beneficial and works as advertised. But since soundbar produces such crisp and clear sound I never felt to use that feature but I tried just to test it out and it worked great. It easily fills 15x20 room with just 50% volume that you would feel like sitting in a theater. Now coming to BASS: It's the most controversial part with Signa series soundbar. When playing dolby movies (I played Batla House and Justice league) the rumble was so huge even at low base level setting that it literally felt like being in the scene of the movie. The rumble penetrated 3-4 walls in my house and could be felt beyond 30 feet. When Polk says "Deep Bass Technology" they are truly honest with their claim. Bass felt like Sub-bass most of the time than normal Bass. Bass is what you can hear, Sub-bass is what you feel in your whole body. I also noticed there was no down firing driver in the sub. When you place your hand near sub you will barely feel anything even while producing THAT deep Bass rumble in action scene. Bass effect is more like 3D and feels like PVR cinema at home. These guys (Polk Engineers & Scientists) know the science of sound and are Master of acoustics so they have done something there in the Bass department. Now the controversial part of NO BASS. It occured mostly during streaming music via Bluetooth or even while playing directly from TV. Bass was so loose & non existent (70% of the time) that one would easily get disappointed. Only thing about the bass present during music is some "air pressure type" loose Bass ,which you can only hear, without having any body,depth, weight or punch. But when you watch dolby/DTS movies Bass will just shock you in many ways that you won't be able to believe yourself. One can easily feel that Super deep Punch and weight with 3D effect. So there's definitely some improvement to do in that Bass department but it won't affect your experience during watching any movie. For music lovers I would suggest to go for Magnify Mini rather than Signa S1/S2. It was very easy to install and I used HDMI Arc to connect to my TV. Using Polk's remote I can turn on Bluetooth ,connect with my OnePlus 7 and stream. I actually enjoyed listening to music since I rarely listen to Bass heavy songs ,so Bass issue never bothers me. I got it for around 14k so it's Value for Money for me and actually delivers more than what I paid for. I received 4 power cables (2 two-pin & 2 three-pin). Received all other accessories like optical cable,HDMI cable, remote, batteries. Thanks for reading my review. Cheers ;)

Sounds OK , solid , good bass and mediums, but lacks of trebles. Good for the price , if you are looking for astonishing sounds it is not your soundbar.
