Review: 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.
Review: Muy bien audio. Se escucha perfecto las voces y en general el volumen es alto. Los bajos son secos y no tan profundos pero era lo que buscaba, mejor que algunos modelos Bose.

## Questions & Answers

**Q: What are the length and height dimensions of the soundbar? How many watts is the soundbar and subwoofer?**
A: The wattage of the sound bar is 40 watts.  The subwoofer is also 40 watts!  That’s 40 watts each!  This is a very nice sounding sound bar!  The room the sound bar is in is 28 feet by 28 feet!  If your not happy with this sound bar, you don’t need a sound bar.  You need a sound system like I replaced with this bar.  My old sound system would shake the house and rattle the windows with 150 watts of awesomeness !  I now have hearing lose from all of the loudspeakers.  It may be impressive to shake the house, but believe me, it’s not worth your hearing.  My wife and kids are always getting mad because of having to repeat themselves so often.  I can hear fine.  I just wish everyone would talk louder! 😂  I was a sound man in a Art Center for over 15 years before retiring.  The hearing specialist said I need a pair of 5,000 dollar hearing aids.

**Q: Does it come with the arc hdmi cable?**
A: The HDMI cables I purchased clearly say they support HDCP 2.2 & 2.3, Enhanced Audio Return Channel (eARC) Dolby Atmos Vision and Hot Plugging.
My advice is look for a cable that has at least a 8K @ 60Hz refresh rate. 7680x4320 ultra HD resolution, compatible with 4K@120Hz and 2K@ 240Hz
I use a much more powerful sound bar but this applies to any TV that has a dedicated eARC port

**Q: What size is the subwoofer speaker**
A: Did anyone actually read his question? he asked the size of the subwoofer SPEAKER...It's 5.25" tiny little guy you aren't gonna get much bass

**Q: Will it work well with a samsung tv? or is it better to use a samsung sound bar?**
A: I have an older Samsung 56in TV built in 2009 (doesn't have a dARC connector) I have it attached with the optic fiber. It works great, but I do use the Polk remote to turn the sound on and off and adjust volume. I was using a Samsung soundbar and subwoofer, but Polk provides a vastly improved sound. And I don't have to continually adjust the volume to hear the dialog like I used to do with the Samsung sound bar.

### ⭐⭐⭐⭐⭐ Review
*by D***E on 3 January 2024*

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!
