Do you mean a Play 1 and Play One? I do not believe the two different speakers will pair for stereo, you can group them to get both playing the same (mono) music though.
Sonos products that can be stereo paired
To create a stereo pair, you will need two Sonos speakers that are the same model (for example, two PLAY:3s). It is not possible to create a stereo pair with Sonos speakers that are different models. It is not possible to stereo pair a Sonos PLAY:1 with a Sonos One.
