So, I have two Play:3's in a room and one of them has lost it's high-end, clearly a failure of the tweeter. When I contacted SONOS support, they had me run through a few tests and came to the same conclusion, however, they offered to sell me a refurb at about $170. Not happy about it at all. I'd be willing to pay for a replacement for the tweeter, but buy a refurb?
I own several SONOS devices... including the CONNECT:AMP, 2xPlay:3, and Play:5. Obviously time to look for alternative.
Anyone else dealing with similar issues?
