Never listened to them but they must sound amazing because they are so pedestrian looking nobody would buy them based on aesthetics.
And if you buy speakers based purely on aesthetics, that's tells me all I need to know about you. And I bet you are "that guy".
I've had better looking speakers in my room, but I've had some ugly ducklings too. Personally I think the Cornwall has an understated look that doesn't call attention to itself (other than the size). It's plenty good looking to me.
