Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

Thanks, @jmolsberg  Here is Stereophile's quick take from the Munich show:

NOTE: The amps being used are TEKTRON (not teutron)  : )

I love single-driver and coaxial speakers and have owned several.  IMO whizzer cones are a compromise and cause as many problems as they try to solve.  Ex: (again IMO) the Omega 3 series sounds much better than the larger drivers.  But they won't play as loud or as low.  The Coherent line from Canada uses a different approach with it's Radian coaxial works great and doesn't suffer any "whizzer tizz." 

Admittedly I have not yet had a chance to hear a pair of Cube Audio speakers but will at the first possible opportunity.

You absolutely  right, whizzer is anachronistic part from  cinema era  and 
I don't now why is came to  High End. How you compare the high quality 
tweeters to whizzer cone ?

I wouldn’t make the assumption that the Cube Audio Nenuphar suffers from some "common" whizzer limitation. Based on all accounts I’ve have been exposed to the Nenuphar is in a completely different category of performance/design success. Generalizations don’t apply here.

All speaker designers know what their speakers are and are not capable of, and all speakers are a collection of compromises.  There is no perfect speaker - that's why there are so many speaker types on the market.

Whizzer cones are a useful tool to help redirect and disperse the high frequency energy from a single driver speaker.  That's fine, but ALL whizzer cones change the response from the driver and add coloration.  Maybe these guys have achieved a design and methodology that works better - I don't know because as I have stated I haven't heard these speakers yet.  But based on what I have owned and heard up to this point, I will say that I prefer my single drivers to be whizzer-less.  That's all.
