admiralspy69 1.0We 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 $120.
calculon68 1.0Polk Audio Signa S4. On the bedroom TV. (2025 C5) Very happy, third year of use. 9/10 It can't do DTS/DTS-MA/DTS:X. (wasn't willing to pay either, since I have AVRs & HT speakers on my other TVs
grassedge 1.0I got a Polk S4 and it’s been pretty good. Decent price/performance
marjuss 1.0I just bought the polk signa S4 for my bedroom and im impressed. Think its around the 500$ mark:)
No-Code32 1.0I 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.
pimparoo25 1.0I 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.
Pleasant-Toe-277 1.0For a small space it’s perfect. It does a killer job virtualizing sound, and the different sound modes all do their job well.
shchowdh 1.0Polk 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.
Silverstreakwilla 1.0I settled on a Polk Signa S 4 should be arriving today, purchased off of Greentoe.
Waffles_McSyrup 1.0I use a Polk Audio Signa S4 with my LG and ATV 4K. I've had it for maybe three years and love it.
