I've seen those ... they're made by
DC 10 Audio. They have lower range models that pop up on Agon and eBay every once in a while for fairly good prices. They also use a unique tonewood diaphram that resonates as sort of an active baffle (I think they use it in pretty much every model).
Anyways, I've never heard them in person, but the wood work looks exceptional and they are pretty high efficiency enough to bedriven by the Decware Super Zen.
This is their Berlin R with AlNiCo drivers at 96dB @ 8 ohms ... not too shabby looking IMO!

The Kabuki is pretty sexy as well and got best of show in Munich 2015 ~ though $16,500 for a pair ...
