The Sonos Playbar is cleverly designed and does great fake surround, but it's better suited to current Sonos customers than newcomers.
The Sonos Playbar integrates the company's best-in-class digital music software into a thoughtfully designed sound bar; It's dead simple to set up and works seamlessly with other Sonos products, and can even be expanded to a true wireless 5.1 system by adding the Sonos Sub and two Play:3 speakers.
The Playbar's heavily processed sound won't please purists; It's also expensive and there are considerably better-sounding alternatives in its price range; Many buyers would be fine with cheaper AirPlay or Bluetooth alternatives.
