Signature Polk sound

Deep Effortless Bass

Signa S4’s powerful wireless subwoofer provides the deep, effortless bass that Polk is famous for, at loudness levels that are surprising for its size. Polk's exclusive BassAdjust™ mode controls bass on both the sound bar and sub ensuring seamless blending. The subwoofer connects automatically on start-up and can be conveniently placed nearly anywhere in the room. Put it up front for maximum impact or try behind the couch to feel the rumble.

Sets Up In Seconds

Set up is easy: simply connect the included HDMI or optical cable (or aux-in on older TVs) for the ultimate sound quality for any TV—even the latest 8K Ultra-HD TVs. Signa S4 is pre-programmed to work with most TV remotes and it quickly pairs to your mobile device via Bluetooth to stream your favorite music. Signa S4’s low-profile design won’t block your TV or your remote. Signa S4 can be wall-mounted for flexible placement.

Rated 5 out of 5 by from HDMI or optical I purchased the Signa S4 yesterday and believe me it sounds really great. Although I have a question, Got little confused while reading the Guide. Connecting through a HDMI cable is better or optical?

Questions

I just recently purchased the Signa S4. It sounds great and the setup was very easy. Can I upgrade the subwoofer with a with another Polk subwoofer? 

Asked by: EJ757
Hello EJ757, The Signa S4 will only work with the subwoofer designed to be paired with the sound bar. You cannot upgrade to another subwoofer as they will not pair with the sound bar.

hi, just considering purchasing the signa 4, but have a question, how far from the sound bar can the sub woofer be placed?

Asked by: Gav1959
Hello, The range of the subwoofer to sound bar can vary based on some factors but generally it can be placed about 20 feet away. Please make sure there is no interference between the sound bar and subwoofer if you plan to place it at the furthest point.

Hello, I just got a S4 from Sam's club. I have some trouble with the LED color changing. For the Atmos format I do get the blue color. However, for other Dolby audio format, the color remains whilte while the manual says it shoud be green.

Asked by: Sysback
Hello, This could be from a few things but most likely is the source since the S4 will playback whatever it is being sent to it. Are you connected via HDMI Arc or Optical? HDMI Arc would be preferred. We would recommend that you give our customer care team a call for live troubleshooting as they would be able to assist you with this. 800-377-7655 (Product Support)

Will this device allow you to connect to more than one blue tooth device at a time? It is not recognizing my phone.

Asked by: Lomo
Hello, This soundbar will not support multi connection at the same time. It can pair with multiple devices but will remain connected to only one device at a time. Please check to see if the soundbar is connected to another device before attempting to use it with your phone. If you have further issues, please contact our customer care team at 800-377-7655 (Product Support)

Why does the sound suddenly cease and to restart it I have to turn it off which also includes tv lgs2 and then turn it on again

Asked by: Grum
Hello, This may be caused by a few things, first I would check the TV settings to make sure everything is properly setup to work with HDMI ARC. Then swap the HDMI cable with a Certified High Speed cable by a company like AudioQuest. If neither of those work, then please contact our customer care team 800-377-7655 (Product Support)

Is it good to use HDMI or Optical cable for best quality sound ?

Asked by: Diago
Hello, HDMI ARC will provide the best sound over Optical as well as allowing for more features to be accessible via ARC. Just be sure that your TV supports HDMI ARC.

My tv is hooked to my soundbar using the ARC hdmi port. My Roku 4k device and blu ray player are hooked into the soundbars extra hdmi ports. Since the S4 only has one hdmi port, will it matter if everything else is plugged directly into the tv?

Asked by: Bengi
Am I able to connect my television And my sound bar To function via the remote control for my Roku, i.e. volume control?
