Needed to finally replace our Sony sound bar that we've had for years, I was looking for something that would be loud when I wanted it to be and something that I could feel the bass in my bones but wasn't looking to break the bank for it ... and voila! Our Polk sound bar with wireless subwoofer arrived today, super easy hook up and we've been enjoying it now for hours! TV sounds awesome, bluetooth pairing with my iPhone is a breeze, idiot-proof remote control ... love, love, love the full, rich sound! Great purchase!

Style: S3 Soundbar + SubwooferVerified Purchase

Was on the hunt for a soundbar that would seamlessly blend in with my many google/nest speakers scattered throughout my home.

The signa s3 was the right price point, it adds bass and top end that the nest audios can’t deliver.

It won’t amaze you with sound quality but at the price point it’s exactly what you’d expect.

Outstanding!

Reviewed in Canada on August 30, 2024

Style: S4 Soundbar + Subwoofer w/ Dolby AtmosVerified Purchase

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.

Not Worth The Money Over TV Sound

Reviewed in Canada on February 21, 2023

Style: S4 Soundbar + Subwoofer w/ Dolby AtmosVerified Purchase

I really was hoping this soundbar was going to be a replacement for Klipsch Soundbar 48" it was replacing (it died) but it wasn't even close. Literally when the wife asks "why are we still using the TV speakers" when the soundbar is on, you know you have a problem. I found "movie" mode the best sounding overall but it still sounded "hallow" like the the TV speakers and I'm starting to think this is a problem with plastic soundbar cabinets vs MDF cabinets like the Klipsch unit was. I tried the dialogue enhancement modes, and although they work, they amplify the "hallow" sound I mentioned above along with the voices. Surprisingly the subwoofer for it's size is fairly good but suffers from becoming too "boomy" when the sound level increases. I tested Atmos with a couple of Netflix shows and the Amazon Firesticks built in Atmos test clip and it sounded "OK" (light goes blue for Atmos content) but I'd rather they have just not included that and concentrated on a good 3.1 channel soundbar. Bluetooth was easy to connect to and in "music" mode it sounded good but that's not what I was buying it for. Really disappointed as I have a fairly high end Polk 5.1 speaker system in my basement family room so was expecting Polk's general level of quality and this just wasn't it. The last issue was DTS support. The Polk page for the Signa S4 doesn't list supported formats and checking the manual also yielded no results and it turns out it has no DTS support! I have some Blueray content with DTS and DTS-HD and it has to be transcoded. I thought today we were past that and they all supported DTS. I'd recommend this a bedroom best case but I think there are better options out there even then for the dollar value.

3-4X > my tv speaker, 15 min sleep can be turned off, great value and sound for a tv < ~10ft away

Reviewed in Canada on January 8, 2022

Style: S2 Soundbar + SubwooferVerified Purchase

I wanted to write this review early because there were so many negative reviews about the auto sleep after 15 mins feature, I almost didn't buy it.

First: I bought this in Jan 2022, and my unit has the option to turn off the auto sleep feature by holding the [TV] button on the remote for 5 seconds. The setup was very straight forward, the manual is 2 pages with pictures, with basically no wrong options.

It comes with a HDMI ARC and optical input, only connect one. I'm using the ARC and the speaker turns on ~10 seconds after my tv, and off ~5 seconds after, which isn't great but it works.

I think the sound is great for the price, but the limitations are very apparent at higher volumes. The movie button gives you pretty good range and base (with some adjustments), but at higher volumes the enhanced dialog settings 3, and sometimes 2, become useless.

I have it connected to my Insignia Fire Tv, and in movie mode at 50-60 volume it’s loud enough that I need to yell when I’m talking to someone a few feet away, while still experiencing incredibly clear sound. The bass on max in movie mode was enough to shake the room.

Overall, it’s exactly what I was looking for at this price point (<$300CAD) and the sound quality exceeded my expectations despite a few limitations with the enhanced dialog feature.

This Sound Bar Is Great ! ( Real Reviewer )

Reviewed in the United States on January 3, 2024

Style: S4 Soundbar + Subwoofer w/ Dolby AtmosVerified Purchase

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!

La mejor relación calidad precio con este artículo que cumple con el sonido espectacular de Polk

Reviewed in Mexico on November 8, 2023

Style: S2 Soundbar + SubwooferVerified Purchase

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.
