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

david this is a great thread! i get immense satisfaction from my omega speakers and decware set amp. i can only imagine what going up the the single-driver chain must be like. at least i can grasp the reality (:

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.

@br3098 
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.
