Roku makes one of the greatest media streaming devices on the market â actually, several of them â but the company is also “streaming out” to new areas â including the introduction of a sound bar as well as some original programming to watch on its eponymous app. It’s pretty cool stuff, too. Let’s start with the “Streambar,” the soundbar you can use to replace (and probably upgrade) the speakers built into your TV. Soundbars are nothing new, and in fact there are so many of them on the market that choosing one is probably a real treat. But Roku’s offers extra value, in that it is not only an audio device but it’s also a fully-fledged Roku, with all of the streaming goodness that means.
