A:AnswerI just went through this on Friday. The brackets only worked with the same model years. I had a 2014 curved sounder and purchased the 2015 65" UHD tv and no dice. I called Samsung and they do not manufacture a replacement bracket either which you would think they would. Geek Squad said they run into this all time. I went ahead and spend the bucks on the 2015 soundbar on closeout and open box price. I will keep and sell eventually the 2014 tv and bar as one.
A:AnswerI might be wrong but as far as I know the only wireless (Bluetooth) is that subwoofer! The soundbar connects via HDMI. The sound bar connects to the subwoofer via Bluetooth connection!
