Style: S4 Soundbar + Subwoofer w/ Dolby Atmos
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!

I really love this sound bar as it provides exactly what I wanted. My TV volume was not loud enough, and I knew I needed a sound bar. At first due to the reviews, I thought this one would not work, but I ended up deciding with this one because it had everything I generally wanted. I think if you are someone who is extremely deep into speakers and sound and theater sound type things you may want something more; but if you are a general person who wants a sound bar, get this one it works very well. The only downside is I wish I could control it from my phone and I can't. That really really Sucks!!!! Otherwise the sound bar is loud. The subwoofer is amazing and really hits and you can control how much bass you want out of it. I'm really happy with this choice.

Style: S2 Soundbar + Subwoofer
After buying one to test for a Christmas present I kept it and bought a second to give for Christmas. I had it 2 months now and love it. It's just nice to have a forward facing speakers in general. Definitely can make you feel like you have surround sound. The bass isn't amazing but it is enought to support the sound and keep it's quality. At first I was getting irritated finding a volume that was between waking up everyone in house and not being able to hear conversations in tv shows. The remote volume button increased by 3 with just a touch of the volume it made me upset because the middle was the perfect setting. I ended up holding down the volume up button and the mute button for like 10 seconds and then tried holding down vol up and down at same time for ten seconds. A combination of or one of the buttons I was long pressing fixed the volume so it only goes up one increment at a time and adjusting placement of the soundbar and the subwoofer thing I bought 4 different kinds of soundbars when one came with damaged shipping box and blown crackling speakers, 2 out of the four speakers made messed up noises. I almost went with Samsung but they are always over priced for the same equipment as cheap model, at least they do that with their Chromebooks. Their phones, even caught not spending money for the security updates we have to install every month, and instead of security updates it was basically a program that changed icon shapes and small things like that to show it did work, only releasing the real security updates at the end of the entire year. Everyone with a Samsung phone and all 600 pre-installed apps at risk of security breach and identity theft unknowingly, my Google phone came with 70 pre-installed apps needed for phone function and works better, faster, clearer and stays connected to bluetooths without constant error notices inability to stay connected long enough to complete a task, I make great video calls and my Samsung Note 10+ dropped every call ever made with wifi calling turned on, constant breaches due to an enormous amount of junk apps and the very many unnecessary platforms that come in Samsung note and galaxy phones, their are always 3rd parties recieving information from texts and media messages, running Samsung, Google, outlook, Microsoft, Bixby, Google assistant, yahoo, free itunes account 6mnths free music, Alexa, Cortana. Internet browsers came with chrome, Google, Samsung, Microsoft, had to download Firefox too. Had to have a Samsung account ending with a outlook email addy, also need to share a Google account to Samsung and combine saved info, everything gets put all over the place photos and documents show up in 4 or 5 different places being saved in your phone to , Google drive, Google photos, Samsung photo gallery, internally in Samsung folders, onedrive, and downloads, Verizon(if u have), Adobe Acrobat pdf reader, Adobe cloud, my files app. So anyway after 4 other soundbars large and bulky, one without the subwoofer for bass that just rattled the bar speakers, and one that wasn't easy to set up and too bulky and none of them have as good sound quality as Dolby digital, I bought a better optical cable which is the only connection to the tv. I didn't use HDMI cable or optical cable they send because if it wasn't twisted or fit in just right the sound would go in and out and make that white noise or popping sound. It wasn't really bad just could have used the HDMI cable they sent but for some reason I had hard time I had an optical cable I bought for a printer/fax/scanner I bought I never knew what it was for... It's so so nice to hear my tv with a front facing speaker!!! I can actually hear the TV all the words without blasting it so all the sound facing back behind the TV no one in front of tv can hear it well and everyone in other side of tv can't hear anything other than the tv... I thought my hearing was going bad for a while. My ex was yelling at her dad his tvs back faces the hall of apartment complex. That's when I noticed that the new TV's being made have back speakers impossible to hear without it being too loud in the back. Tried cardboard and foam to block sound and bounce back to me. No more of that now. My Polk signa Dolby soundbar is clear and great quality I find the sweet spot being in the voice adjust buttons low voice is 1, loudest voice adjust setting is 3. Voice adjust 2 is my favorite setting with bass turned down just a few and volume turned up 2 notches. My other favorite is the night mode turned up volume just a little. I can finally understand more than gunfire and explosions and crashes now I can hear what they are saying on the tv too. I love how slim this soundbar is, not as easy to damage doesn't block my remote sensor on bottom of tv, can wall mount without worry of it being too heavy or big. If you find yourself having to make adjustments to volume more than you would prefer to have to do, then consider moving your soundbar and separate bass system to different loctions. Maybe set in front of tv should be changed to mounted on wall just above tv and bass somewhere close to the tv my bass is set to the side but kind of behind the TV on the tv stand and I mounted mine just above the tv far enough the remote reaches it from my sitting angles and it's been way better than when I put it in front of tv. Great sound quality from the small soundbar shocked me enough to want to buy one for my father. Luckily it was on sale because I do think that 250 bucks is too much for this system. Especially the quality of the subwoofer sure it adds a bit of needed bass but only low low level because this subwoofer just makes everything muffled, at the right setting with volume it does a good job making your tv viewing a happy time with good clear sound. Any speakers with Dolby digital sound you can pretty much count on decent sound quality. It's not Bose but for the price I feel it's just as good. I have strange issues though, years of work has made it hard for me to hear anyone speaking to me if I can't clearly see them, it's like I have to be close enough to read their lips to hear them clearly. If I am not close enough to see the words their mouths form it just sounds like everyone is mumbling nonsense and made up words all day, but at the same time I suffer from sensory issues that have to do with sound and their pitch or frequency and what the sound is. Electric outlets plugs phone chargers light bulbs I can hear them all running. High pitch frequency both my parents could not hear my little sister couldn't hear it and neither could my older sister, to me it was like the highest piercing noise that ignited an immediate emotional reaction of pure hate and rage that noise made me want to dig my brain out through my ears. It was coming from a clothes dryer that had a problem with the belt or gears that spin it. I almost was put on psych hold after the rage hit again and I shoved the dryer on its back and started beating it while screaming at my mother for running it while I was home. My little stunt brought that high pitch squeeling down and now everyone but my dad could hear it. Thank goodness mom knows I'm bipolar but this experience wass new to me. And different noises have different responses that I can't control. A buzzing street light across the street and down the road to the 4th house the street lamp on the corner was new looking like an LED lamp. I could hear it in my house 5 bedroom 2 bath 3 story home I could hear the buzzing from that street light that sound caused and anxiety and serious need to find what's making that noise and stop it. I thought it was the hornets I didn't see any nests yet so I figured they got in the walls that year and had my ear against every wall looking for a warm buzzing area In the walls. Then at 3a.m. in gross pajamas and socks no shoes I wandered around my house down to the pond at the park up on my neighbors porch inspecting the pool filters that were running thinking that could be it it took me 2 hours of searching for this buzzing that seems to be coming from everywhere. Until finally I realized 4 new street lamps were looking like energy saving LEDs or something and only one was buzzing like that so far away no one believes me that I could hear it in my room watching TV windows doors storage and all the house in between me and that light. I'm on 3rd floor up high with the street lamps I think that's why I could hear it like it was in my walls. Once I got outside the noise was coming from above me and I could hear it so clearly from so far away it took me forever to find the source of this anxiety inducing noise I couldn't turn off. Causing such anxiety no other thoughts but making it stop could come into mind, going around the neighbors homes yards porches pools round and around staring up at the sky at 3a.m. Finally I smartened up bought noise cancelling headphones!!! Anyway I love the different adjustments to the volume that can be made with six different modes and can move the bass and volume as you need to adjust. I switch between voice adjust 2, and night mode lower the bass. I'm very happy with this purchase just maybe spend a few bucks in a really good cable to connect it because even though they included multiple ways to connect this soundbar, a better quality optical cable and a proper HDMI enhanced audio or whatever I went with a 10 dollar optical Optical Audio Cable 10ft/3M, iVANKY Slim Braided Fiber Audio Cable, Digital Optic Cord,Toslink Cable, Aluminum Shell, Gold-Plated for Sound Bar, TV, PS4, Xbox, Samsung, Vizio - CL3 Rated Amazon's Improved sound quality by a LOT Choice in Fiber Optic Cables by IVANKY

I have had 4 sound bars of different manufacturers on my 5 year old 75" tv . Something always has gone wrong with them-- remote no longer would connect-- or the bar died, or some of the "features" would no longer work-- thought that I would get a little better one this time around so I bought this Polk sound bar-- it is simplistic to use, adjusts the sound well, and the sub woofer has good bass. Very happy with it-- let's hope that it's a "keeper"!!

Not bad for a sound bar and subwoofer! I currently use it for my TV upstairs so I can get ready for work with some needed bass to get my day going. I found the power cables to be a bit on the short side for my needs, I ended up buying a 2 pack of 10' 2 prong electric cables and it worked out great! The sound is great, nice and clear which is what I expect from Polk Audio. There was a user on here that said Just BUY it already and based on that I did. Thanks for helping me decide!
