I recently bought the Roku Streambar and have the Roku Subwoofer being shipped to me this week. I am wanting to get the official Roku wireless speakers but they are nowhere in stock either in store or online. My local Walmart has one set of the Onn Roku wireless speakers in stock. I know you don’t get the two remotes with the Walmart version but is that the only difference? Are they the same in wattage?
