A:AnswerGet the swa-8500s wireless rear speaker kit made by samsung they pair up extremely easily and all of the rear speaker controls are controlled directly through your sound bar. I have the exact same setup and it sounds great.
A:AnswerI do not know about HW R650, but it is compatible with HW Q60R soundbar which is what I have. I believe the product manual or bestbuy rep will be able able to provide the information on compatibility between the soundbar and rear speakers. Hope this helps.
