I think I saw Zu speakers at an audio show only once. They kept me less than 30 seconds in the room. Don't remember the model or any details, just the brand.
Also, I remember reading this comment about some Zu speakers (yes, it was for a cheaper model):
**** Munich High-End 2016 ****
"Right: Zu loudspeaker from whizzer cone driver and compression driver fitted with waveguide. The speaker sounded plain awful. Close to worst sound on show."

Nice ad, though.
