Do I need an extra loudspeaker if I buy only the Playbase?
It totally depends on your needs. If you just want to get a bit better sound out of your television, only the Playbase might be enough. It already has 10 amplified speakers, six midranges, three tweeters, and one woofer and these hardware guarantee that your listening experience will change forever.
Obviously, at least one of these wifi speakers are also required for a complete home sound system since there’s no way to stream music to your other rooms in a truly wireless way. If you already purchased a Sonos Playbase or Playbar paid $699 for it, there’s no reason not to get only one Play:1 for 199 bucks and see how it works and how much value it adds.
