A:AnswerAll I could say is that my hw-r550 works superb swa-8500S and then I added a j-tech digital adapter model JTDSP0103 to help me connect one optical and feed three oouts to sound bar and PYLER amd and ONKYO AMP and I am super happy 13 speakers 4 subs you feel that you are there at only 10 volume make sure you get gold plated optical
4 x 6 ft opticals cables and they sound great
A:AnswerYou got the right ones. The wires only connect from the speakers, to an actual receiver. The receiver connects wirelessly to your soundbar. It is better than wires running from the soundbar around the walls to get behind the couch. Or having to remove the carpet and running them that way.
A:AnswerYes you can purchase longer speaker wire. But you need to know that both speakers need to have the Same length in order for the same sound quality to be produced.
A:AnswerAs long as your Samsung Soundbar can connect to Bluetooth like on your phone, then yes. I have a set and my brother just bought a set yesterday and I helped him connect them to his soundbar too
A:AnswerI dont think so. From what I can find it doesnt look like your sound bar supports additional speakers but its best to email Samsung for verification.
