Hello everyone. I have setup my 2 new Sonos Fives with Sub Mini and noticing that one of the speakers sounds like it plays in a mono mode, like if the tweeters were not on or something. I don't know how to better describe the issue... I have tweaked every possible setting that I could think of, but nothing worked. Currently, the music plays through a smart phone and is hooked up using line in connection.

Anyone has experienced this? Thanks.
