JUST GET IT ALREADY, you’ll love it.
I got the S4, if you’re teetering back and forth just stop, get it. GET IT NOW! I love it, I think you will too. Don’t get me wrong, this thing is not so amazing that the walls our going to vibrate it’s gonna sound like a concert in your home; no soundbar out of a box is going to do that. If you want that effect, prepare to fork out four digits on a system with superheavy speaker magnets and an independent amplifying system. What sets this apart is the clarity and simplicity, not to mention quality. And btw, it is loud enough to piss off any inhabitants in the same dwelling or sharing the same walls as you. Here’s what I had to do to set it up, I opened up the box put the batteries in the remote, plugged the power cord of the soundbar to the wall outlet, did the same for the subwoofer, turned on the soundbar, activated the Bluetooth on the soundbar, pressed the button on the back of the subwoofer for it to connect to soundbar, got the tv to check for any Bluetooth items nearby and it saw the S4 immediately and I selected it on the screen. VOILA, the system was set to go. Seriously, that easy, 5 min! For basic sound, my tv remote was able to function the volume automatically. Now basic functions for the remote that comes with the soundbar, this is everything you’ll need to know about controlling the sound: There’s the volume up and down and there’s the bass up and down, pretty basic. There’s three available preset eq’s set up (each of those buttons has icons). 1- movies/cinema, 2- night mode (which controls the highs and lows for a steady volume and tone, that’s to avoid pissing off others late at night), and 3-Music mode. That’s it, it’s not like a fancy equalizer or amplifier, that’s all the control you get. At the very bottom of the remote you’ll see buttons with the numbers 1, 2 and 3. That’s basically treble, it control voice clarity. If you’re having trouble understanding what people are saying just take it up to 2 or 3 and voices are louder and more clear. And that’s it! Now, if you want to get fancy, you can put it on a bracket and attach it to the tv (which, I did) or there are two holes already provided on the back to mount it to the wall with screws. It does come with HDMI and optical cable if you want to hard wire it to your tv, but hey, I’m happy with the Bluetooth; only cables I had to deal with are the power cords for the bar and the woofer. It’s choice! Stop fidgeting, for the price point, get it!

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 “expands” the soft and loud sounds as if in a movie theater but with 2.1 speakers. The Night mode “compresses” the sound levels, making “quiets” a little louder and “louds” a little lower. This mode is good for late night listening with the sound turned down so that others aren’t disturbed by loud explosions and you can still hear the “quiet” 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 isn’t 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 “standardized” level could be selected for particular circumstances.

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 15×20 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 😉
