Translation:
Good afternoon, I wanted to ask a question that I have, I have the Sonos Beam 2 bar and I would like to put two surround speakers in the back, I would like to know which models I can install and if they are plugged into the power or would go through Bluetooth or some system, thank you very much.
Response:
Have you looked at the FAQ on the sales page here?
The surround speakers change from connecting to your router to connecting to the Beam, via a ‘hidden’ 5Ghz connection.

Los altavoces envolventes cambian de conectarse a su router a conectarse al Beam, a través de una conexión "oculta" de 5 GHz.
