Rated 5 out of 5 by from Perfect balance We recently moved and decided to downsize our audio system so we sold our huge speakers and amplifier. I started researching soundbars with wireless subwoofers. So many options and most with very high prices. I finally whittled it down to two options. This Polk and a JBL option. The JBL had a bigger sub and I thought it would blow this Polk away. We found both at a local Best Buy and decided to test them both out. Tried the JBL first and honestly was not impressed. The sub and mid bass were muddy and the highs were too brittle. When we tried the Polk it was night and day. I’m not claiming the sub blew me away. It didn’t. It drew me into the soundscape and I found myself listening to near perfect balance of highs miss and lows . It was almost like our $4500 multi speaker system. If you are looking to make a big impact on your movie night this is the way to do it without taking out a loan.

Rated 5 out of 5 by from Incredible clean sound I tested it on an eBay store and couldn't believe the clearest soundbar in the store. Pros Subwoofer is not drowning on high volumes. great for classical or rock music. I can feel DTS and Dolby, it should be connected through eARC HDMI This soundbar is the only one with aux in feature within this price range and has Dolby (aux is a must for me) Movie, conversation, music mode along with conversation level, that's great feature if you have a baby and still have time to watch movies when he/she sleeps Cons: If your area is larger than ~ 400sqft, I definetly recommend max model. The remote control could have been a better design

Questions

Can subwoofer be placed anywhere in room?

Asked by: Lugie
Hello Lugie, The subwoofer can be placed anywhere within the room but we would recommend experimenting with the placement of the subwoofer. Due to the subwoofer being wireless, you can easily move it around to see what sounds best for your room. Start with placing it in a corner and then move it around based on how it sounds to you from your listening position.

Does this soundbar have the capability to connect wired satellite speakers? If not, do you offer any other sound bars with that capability?

Asked by: Scotty Mac 7354
Hello, None of our soundbars offer the ability to connect wired satellite speakers. Our React and Magnifi AX sound bars offer the ability to connect wireless SR2 satellite speakers.

I have an Amazon TV (made by TCL) and it randomly disconnects from the Signa S4 while I am watching OTA TV. There is no pattern to it that I can discern, and I cleared the soundbar settings on the TV and re-installed soundbar to the TV, still happens.

When I turn up the volume by one click it goes up by a lot and is hard to find a good volume, especially at night. OLED tv connected via earc. Any way to fix this? Your command bar is not as sensitive 

Asked by: Phil14
Hello, we may require a bit more information to answer your question. However, I assume you are using the Television remote with eARC. If this is the case, the Television is operating the Volume increments, and there is no way to adjust this. Using the Soundbars remote can help provide fine volume adjustments. For further assistance, please reach out to our product support team directly by calling 800-377-7655 (Product Support) Mon - Sun: 9AM - 9PM EST - https://www.polkaudio.com/en-us/contact-us.html

If you are using a Roku stick what is the best way to connect both the soundbar and the Roku stick to the TV. I want to use only one remote my preference is the Roku remote. I know HDMI provides the best sound.

Asked by: Pk205
Hello, We would recommend that you connect the soundbar via your TV's HDMI eARC port or ARC port if it does not have eARC and then the Roku to another HDMI port on the TV. This will allow the TV to transmit the audio signal to the sound bar and with CEC you should be able to control the volume and power for the sound bar. Please note for any sound adjustments you wish to make on the sound bar, like bass or treble, you will still need the sound bar remote to control those settings.

Hello, will this soundbar decode signal with ARCHdmi or is it especially intended to use with eARC only,,???

Asked by: Ronl
Hello, This sound bar can be used with ARC only if that is all you have but it can work best with eARC. You will still get the sound bar to decode signals just fine with ARC.
