Sonos' plans for its Play:3 network radio were mostly given away Monday after the discovery of a brief Amazon listing (cached). While it didn't settle the name, the post confirmed that it would be a shrunk version of the ZonePlayer S5 with three drivers, two of which would be mid-range while the third would be a tweeter for the high range. Deep bass may still be a selling point with a bass radiator to push the low end.
