That's the thing about them.
A small traditional PA usually sounds like a PA and it undermines the *acoustic* aesthetic.
The BOSE system reinforces the acoustic aesthetic.
My criticisms of the system have to do with the way Bose claims that the system can be scaled into a larger system. I don't think that is realistic; there are specific reasons that large PA are laid out the way they are and BOSE sort of ignores that.
They seem perfect for reinforcing someone who wants to sound acoustic... and I'd wager that this can lead to being appreciated by an audience in a tangible way.
