Hi @Bill Fuller.

Welcome, thank you for reaching out to Sonos Community, We appreciate your time and effort in posting your concern here in our community.

For surround, you can only add two small speakers (Sonos One’s) if you have a home theatre setup, for additional speakers you can setup them as a group speaker and it will have the same sound quality as your playbar.

Here are some links you can follow as your guide.

Let us know if it works. If you need help with any other information, please be sure to let us know.

thank you mark p.
