A:AnswerHello Smart! The Roku Wireless Subwoofer requires either a Roku Streambar, Roku Streambar Pro, Roku Smart Soundbar, or Roku TV with Roku Wireless Speakers.
A:AnswerHi Eric! Your Roku Wireless Subwoofer is designed to connect with a Roku host device such as a Roku Streambar, Roku Streambar Pro, Roku Smart Soundbar, or Roku TV when Roku wireless speakers or a Roku TV Wireless Soundbar is connected. It cannot be connected directly to your TV, or an existing sound system.
A:AnswerFrom my understanding you need the sound bar in order for it to connect seamlessly. I have the sub, speakers and sound bar which sound great!
It is not the top of the line however, I hooked it up in my bedroom and it is more than enough.
A:AnswerHi! Currently the Roku Wireless Subwoofer only works with the Roku Smart Soundbar, Roku® Streambar™, or a Roku TV™ with Roku TV™ Wireless Speakers.
A:AnswerNo; This Sub will only pair with the Roku Smart Soundbar....if you don't have that, it won't work, doesn't matter if the TV is a Roku TV or not/
A:AnswerThere's no separate volume control per se with the sub. In the Roku audio settings, you can set the sub to no bass, low bass or loud/high bass (can't remember how the last 1 is worded). Hope that answers your question.
