I recently bought the Roku Soundbar and subwoofer. It rocked pretty well! That said, I thought to myself "bluetooth can support multiple devices, I should add a 2nd subwoofer to really shake the theater room". I was disappointed to see this isn't possible. My question is, why not? Seems like a ridiculously easy feature to add and then people could buy multiple subwoofers instead of just one. Is this something that may happen in the future?
