Question: sonos play 1 how many?
Answer: Sonos Beam, Sub, and 2 Play:1s You can use any two speakers, as long as they're identical. I've used two Play:5 speakers, but it's overkill. Two Sonos One speakers are a better match, but if you are getting a Beam, it has mics in it, so save $100 and get two Play:1 speakers. They sound just as good.
