Thanks for all the great questions here. Currently, one pair of Roku TV Wireless speakers can be used with each Roku TV. When using Roku TV Wireless Speakers, your TV's internal speakers will be disabled. We have some helpful FAQs and more information about the features and specifications of the speakers on our website here: https://support.roku.com/article/360006291054-what-are-roku-tv-wireless-speakers-
I'll be sure to pass along your other feedback and suggestions to the team for future consideration.
If you're running into any issue with your speakers or need more help from our team, feel free to get in touch with us here: https://support.roku.com/contactus
