Hi @blueduck7842,
A warm welcome to the Roku Community!
Thanks for posting your inquiry, and we appreciate your efforts in letting us know about this. Kindly be advised that you can only pair one wireless subwoofer to your Roku device at this time. In addition, this is an idea and feedback that we'll pass along with the team for review.
If there's anything we can assist you with aside from this, let us know.
All the best,
Kash
