Rated 5 out of 5 by from Excellent sound, simple and straight forward setup WOW... Just WOW... This is probably the best sounding Dolby Atmos soundbar I've ever heard in such a small form factor too! The setup is super simple and works great with a TCL with Google TV. There's no Built in Chromecast or Wi-Fi, so streaming to the soundbar directly isn't an option. Three straight forward modes to choose from works very well. So, if you're looking for a simple plug and play soundbar that just works seamlessly with your TV with GREAT BASS... Check this one out! Worth the sale price I purchased it for. Thanks.

Rated 5 out of 5 by from Great Sound and an Even Better Value! Absolutely fantastic so far! For the price, I can't imagine it gets much better. Easy to setup and a major upgrade over the TV speakers.

Questions

Can the S4D be controlled by the Alexa remote when connected to the latest firecube?  

Asked by: Lee55
Hello, the Polk Audio S4D soundbar can be configured to operate with the Fire Cube with proper setup. Using the HDMI ARC connection and HDMI CEC, the Fire Cubes remote can control the soundbar's volume and power. Be sure to connect HDMI ARC between the TV and Soundbar and activate the CEC function in the Fire Cube and the Television. Depending on the Television, there may be additional settings required. For example, setting the TV to external audio may be required. The new Fire Cube also offers remote control functions. If further assistance is required, please get in touch with our support team. https://www.polkaudio.com/en-us/contact-us.html

Can wireless surround speakers be added to the SIGNA S4D system?

Asked by: Bells
Hello, Because the Signa S4D is a self-contained system, it means it does not support for other speakers to be added. If you like the idea of having surround speakers with a Soundbar, here is a link to a nicely featured system: https://www.polkaudio.com/en-us/product/home-speakers/home-theater-systems/react-surround-system/BN1019-SF.html

What frequency do the soundbar and subwoofer use to pair? My subwoofer occasionally drops connection with the soundbar, and I’m trying to figure out if it’s due to interference from our wifi router 

Asked by: Dean W
Hello, the Polk Audio Wireless Subwoofer communicates with the Soundbar via an RF signal. Your Wireless router and other wireless devices may be causing the interference. Try and relocate either the Wireless router, wireless devices, or subwoofer. If further assistance is needed, please get in touch with our support team by visiting https://www.polkaudio.com/en-us/contact-us.html

Does the Signa S4D support DTS format? P.S. Why is it required to agree to "terms and conditions" for a customer to ask a question regarding your company's product? If one was at a store asking the very same question it wouldn't be required would it?

Asked by: MJD1
Hello, the Polk Audio S4D soundbar has Dolby Digital and Dolby Atmos; it does not decode DTS formats.

I have an LG OLED65B7A tv, will the sound bar power on automatically when the tv is powered on, or do I have to turn on the sound bar with the remote that is supplied?

Asked by: DonO
Hi Don0, The Signa SD4 is designed to become active from standby when an HDMI connected source as modern as your LG OLED65B7A is switched-on.

Is the Signa S4D model a refurbished product being sold as new product??? It doesn’t state that in the description or anywhere on the webpage, but one of the answer to the question on here is suggesting that.

Asked by: LikwidOcelot
Hello, Our products - including the Signa S4D - are brand new unless listed on our website as being refurbished. We have kept the price down on the online exclusive Signa S4D by not including an optical cable and using less elaborate packaging.
