r/SoundbarsWhat's a good but affordable soundbar from best buy?
3 months ago

We bought the Samsung b650F and we were not impressed at all. It was way too crisp with too much treble and not enough low/bass. It actually hurt our ears to listen to. We tried all the settings and couldn’t get it to balance out. The Polk audio signa s4 was on sell for $359 and still might be. That is a very good sound bar/sub for the money. Even the Vizio 5.1 SE we have has better sound than the b650f and that was $120.

r/LGOLEDWhat soundbar are you guys using with your LG OLED? On a scale from 1-10, how happy are you with the purchase?

Polk Audio Signa S4. On the bedroom TV. (2025 C5) Very happy, third year of use. 9/10 It can't do DTS/DTS-MA/DTS:X. (wasn't willing to pay either, since I have AVRs & HT speakers on my other TVs

You can sign up at Polk and get 10% off your first purchase. It’s on sale now for $359 before the discount. I just ordered one. It seems like a solid choice to start out. I considered those three from Costco as well as a JBL Bar 500.

What’s wild is JBL and Polk both appear to fall under Samsung (parent company). It’s wild how many of the audio brands fall under them now. I ordered the Signa S4 as well and strongly considered the JBL Bar 500. The 10” sub at least at a friend’s house overwhelmed the sound from the bar. How do you like the 5.9” Signa S4 sub?

I'd personally go with the JBL. I had a JBL for well over a decade and it sounded and worked great. Plus JBL ONLY manufactures audio so that's their only focus (Sonos does as well, but it's pricer and you don't get a subwoofer). I think you'll really enjoy the JBL. But as someone mentioned below; I moved from a JBL to a Polk myself, and it sounds fantastic; so much better than the JBL. Granted it's hard to compare a 12 year old JBL with a brand new Polk as audio technology is much more advanced nowadays, but I absolutely love my Polk. I also have the Signa S4.

The way companies fall under each other nowadays is absolutely wild; I agree with you. It's hard to even keep track sometimes! lol.. I was also considering the same JBL as you last year, and I might've gone with it had I not stumbled upon a really good sale with the Polk. The one thing I was hesitant about regarding the JBL was how strong JBL is known for their bass, and I wasn't sure if I wanted that in a soundbar. I think the Signa sub is perfect for what I was personally looking for. It's not going to blow the floor off, but it compliments the soundbar quite nicely, and you'll still get some rumble as well. Admittedly I don't use it for any music, but for TV, movies, and games; I have zero complaints with it! I think you'll enjoy it!

r/tcltvsSound bar sound system ideas for small room, 55 inch TCL QM7K, for clear voices
6 months ago

I bought the polk signa s4 specifically because I have hearing loss and needed something to make voices clear. It works perfectly for that purpose. Has 3 levels for improving voice clarity and also has a night mode that keeps volume consistent from scene to scene. I also have the QM7K and they work perfectly together. TV remote controls the soundbar without issue, but you do need to use the soundbar specific remote to change the settings I mentioned.

r/SoundbarsWhich soundbar is better? Polk vs Bose?

I have the Polk Magnifi mini ax set up on my PC, with the added rear speakers, and Polk Signa S4 for the main TV. And I have a Bose Soundtouch 300 on a TV in the gym.

I don’t have the Mini hooked up to an Atmos source, but the surround is very good. Atmos from the Signa is great however.

r/SoundbarsPolk Signa S4 or better option for small living room?

For a small space it’s perfect. It does a killer job virtualizing sound, and the different sound modes all do their job well.

r/SoundbarsAny good Black Friday deals for soundbars?
3 months ago

Polk Signa S4 if you can find it locally. I found it at my local grocery chain (Meijer) for 200 as a Black Friday deal. Not sure if that’s how much they normally sell for locally outside of deal prices.
