    Chromecast isn't REAL

    Polk Signs S3 is a great product -- setup is effortless, sound is fabulous BUT I thought I was upgrading my JBL SB200 when I bought Polk's S3 for its built-in Chromecast but I wasn't! What I didn't guess was that Polk's Chromecast isn't REAL Chromecast -- it won't cast video from YouTube, from Amazon Prime, from Netflix, from Britbox, from Hulu, from Magellan, from SlingTV, from ANYTHING!

    Polk Audio Soundbar and Subwoofer are great

    I purchased this soundbar and subwoofer to add to my 70" TV after looking online and instore at a lot of soundbars. It connected to my TV almost effortlessly and sounds great. I also like that you can adjust the level of the voices in a movie to hear the dialogue that is going on easier. It also sounds pretty good when I want to listen to my music using bluetooth connection. I would recommend this setup to anyone wanting good sound at a decent price without breaking the bank.

    Solid Soundbar

    Overall satisfied with the sound bar. We compare this to the JBL sound bar at the same price point and preferred the Polk audio one. This works well with our TCL class 5 50-inch Roku TV. Main drawbacks are it doesn’t have a great display for the different modes and it’s difficult to understand which mode to use at certain times. There also doesn’t appear to be a default, “normal” mode. That said, the sound quality is excellent especially for music and streaming music apps. It also has a small footprint and it’s very easy to set up. It’s in a green so well with our TV using the HDMI ARC input.
