Good clear sound and clarity makes it sound very good.
Printer –
This speaker bar sounds wonderful. The subwoofer really does a good job with the bass and no distortion.
TheNewGreenLantern –
Pretty good sound and can get loud. Needs more increments on the volume levels, my preference is apparently between two settings where one is just too quiet and the other is just too loud.
Airdan23 –
Overall decent soundbar good value for the money really like the speakers firing upwards for Dolby Atmos
Frig –
The separation is lacking and the bass has no midrange.
mimmie –
Impressive sound bar the adobe Atmos really does work well. The base could use a little bit more of a punch but it’s more than efficient for a basic enjoyment of television
George –
Overall decent product .. sound cuts out briefly on some programs and also cuts out on every volume adjustment. Sound is good though
Arch24 –
Setup and use is great. Now, 2 months in, I hit volume up ONCE, and it immediately went to max out which caused the whole system to not respond as it was treating like I was holding the volume button non stop. Took out and replaced batteries, no change. Did a reset on the sound bar, same problem. It does it with volume up or down. Took apart the remote and couldn’t find anything visibly wrong. Just ordered a remote from amazon hoping that works better as I do really like the sound quality.

My son loves this speaker and is happy with this purchase.
Todd757 –
Sounds incredible!! Crisp sound and deep bass. For $250 its a really nice upgrade from the tv speakers. If you want an overall great sounding system i would buy this.
HeatherI –
Bought this for my nephew’s room. It’s amazing. Very clear sound. We have to ask him over and over to keep it turned down! Very nice. Immediate online order and picked up in the store flawlessly. Thank thank.
ApirakD –
The sound is very good. However, the sale men did not tell me that it was not compatible with SR2 rare speak. I will have to return it because of that.
dishwasher –
great sound, although I’m having issues with it pairing with the TV. The technician said I can use just 1 remote but sometimes the TV reverts back to the TV speakers on its own
Artbo –
I listened to several sound bar’s in the store and I thought this one sounded excellent for the price I had in mind.
RomulusR –
This TCL tv is a great value for the money! Great picture and the gaming setting is outstanding! It’s true that internal speakers are not high quality but they are okay. It will take some getting use to the settings but will be worth it once you calibrate it the way you want to. When I first tried to sign in to my Google account I was unsuccessful and the session timed out, but was successful second time around! This was annoying and made me angry! I understand that they are trying to protect accounts but ridiculous! Had to purchase a new TV mount, Vesa size is 400×300. Overall this is a great TV for the price! Very Happy!
Atlantis82278 –
Great s ok und for the cost. We really like the voice amplification, makes movies so much easier to hear and the bass is perfect dor us
DavidB –
Hook up was easy and it sounds great! Very happy with the quality of produce.
Lightman –
Can’t go wrong with Polk… outstanding sound. Huge upgrade from the TV speakers. Works great with my Sony 50″ I purchased a couple years ago. Black Friday deal was the cherry on top.
LauranceP –
Love it, wish I didn’t have neighbors so I could test its full capabilities.
DMC1 –
For just a sound bar and sub with no rear speakers, it sounds great!
Mar24 –
Awesome sound, and really easy to set up. I recommend it to everyone who wants top quality.
DanielB –
This unit sounds great. This is my 2nd polk soundbar. I have one on my porch under the roof and only use it for the bluetooth and it rocks my entire yard.
DavidP –
Works GREAT and sounds GREAT. Love that you can choose how loud voices are.
MaryD –
Great gift. The sound is amazing and my husband loved it!
techfriend –
This is a good s/b for a small room, but, a very good s/b for a large room. This soundbar is big and gives out big sound ,the sub is good not great.
LizF –
Over priced for same quality as something half the price.
JoshR –
Bought this on Black Friday to pair w a 65″ CU7000 Samsung TV for my bedroom. It’s very impressive, fills the room w sound and I was a little skeptical about the sub being so small but it punches pretty hard and really adds depth to everything.
JimR –
We weren’t sure a sound bar was needed but. With the wife’s hearing difficulties we decided to give it a try. It works. Dialog is easier to understand and movies are great.
Trevor –
This is only my 3rd soundbar overall. I got this to pair with a 50″ Sony that I have in my spare room, which has turned into the movie room for me now. The voice adjustment feature is actually pretty nice. The sound that comes out of this this is pretty amazing too for the price. Only complaint is the sub is a little too much at times, even when turned all the way down, just depends on the movie.
Overall, I would definitely purchase this soundbar again. Especially at the $250 price point, it will be hardnto find anything better with Atmos.
Chang0 –
Easy setup and great sound. My intent was to purchase the Bose 900 smart soundbar and sub, but decided to compare it to the other systems. Sonos produces the same quality sound at a comparable price point but also offers the flexibility to add speakers wirelessly via the Sonos app. The potential to create a whole home system with Sonos changed my mind and I’m very happy with my purchase.
DaleD –
I’ve had this Polk Audio system for over a year now. Great sound easy setup with my Sony TV……not disappointed with the performance for the price at all. There are much more expensive units out there, but this one serves my needs perfectly!!
REBARE –
Has helped with hearing voices and watching movies more interesting
Wifi –
Great sound. Easy to install. Live it! A great deal.
MichaelL –
My LG TV had poor sound quality and Polk Signa S4 sound bar greatly enhanced the sound. Using the HDMI cable it was easy to install and integrate with the TV through the television settings option so that it turns on and off when the TV is turned on and volume is controlled with the TV volume. The Bluetooth option also works well with a phone audio source. I have not tried the voice enhancement feature much, but there is some improvement in voice over background sound. Overall I’m happy after having used it for about three weeks.
Keveeo –
This is a decent aoundbar. I will probably upgrade in a year or so just because i want it to rattle the house:)
TylerS96 –
Overall i find the soundbar to be a great purchase. My only dislike is lack of a numerical volume indicator
HobieC –
Sound bar was easy to setup and it sounds great. I like the bluetooth feature also to play music from my cell phone.
Ronman –
I purchased this S4 soundbar with a new Sony Bravia 5 months ago. After turning the TV on, I get a message stating “Switching to internal speakers.” I have to go into the TV settings and manually switch the setting from “Internal speakers” to “external audio system” EVERY TIME. Also, the soundbar will not turn off when I turn the tv off. I have to use the soundbar’s remote. I have tried everything including resetting the tv and soundbar, replacing the HDMI cable, etc. I finally moved the soundbar to the bedroom and connected it to my new LG OLED TV. The soundbar will turn on when the LG powers up but will not shut off when I turn the TV off, I have to use the Polk remote. When I contacted Best Buy I was advised I had exceeded their 30 day return limit and to have a nice day… My Samsung 3.1 soundbar works flawlessly with both the Sony and LG TV’s. Everything is configured correctly. I contacted Polk support and got someone in the Philipine’s that was English challenged and clueless, reading from a script and zero help. Note: I am an Aircraft Mechanic/Inspector/Engineer. BUYER BEWARE, It’s JUNK.
MadhuA –
Great sound quality, changed my viewing experience with added sound quality. Bass is really clean and not ear hurting even with high volume.
BarryD –
Love this sound bar. Allows you to hear in high def and stadium modes. Great movie quality for the price
BobF –
We purchased this equipment for our youngest daughter’s Roku television. Easy installation, great sound and excellent pricing.
Abbadabster –
I am very picky about sound quality. I found this speaker and subwoofer to be excellent for a reasonable price. The quality of sound is exceptional, the packaging of the product was great, and the set up could not be easier compared to multiple other speakers I have used in the past. Well done Polk! If you keep up the sound quality and the product lasts, I will give you my business in the future. Thanks
Murph –
This thing BUMPS. It has, likely, a hundred volume settings that are shown by 5 LEDs and I’ve never had to go above 2 fully illuminated ones and one barely there one.
When I first purchased this I turned it all the way up, laid on the floor of my unfurnished, new-to-me, home and played this (https://youtu.be/3VZFpwlXKpg?feature=shared) audio test by Dolby and was literally and figuratively blown away.
One thing that I wish this item had was the ability to add rear/wireless speakers like some of the higher level Polk systems allow.
Packaged well. Set up was easy. Sound is phenomenal. Looks slick. 10/10
