Thanks for sharing your fabulous outcome, sincere congratulations. People who look at the Nenuphar as merely a single driver speaker and question its value just simply miss the point. A speaker doesn’t require multiple drivers, weigh 300-400 pounds with measured bass to 20 HZ in order to be considered superb. There are alternative paths to achieving sonic excellence.

Yes
Folks worrying over capturing the 20-40hz zone may be going down a  wrong path.
I wanted to add a single sub to my Thor speakers,,so I ordered a sub amp + 10 inch woofer, , a  local tech urged me not to go that route. He said why do you want to add something that will lower the quality of bass the Thors already have. Further research on Troel Gravensens page, where he entions his dual per cabinet Nextel W18003s (Titanium voice coils, which Troels helped Seas to design) gave a  **seemingly rich deep bass as if 20-40hz*** = due to dual 6 inch cone material for bass.
IOW dual W18's provided sonic bass which sounded so rock solid, , to 40hz, as if 20hz were being voiced.
There  is so  little music in the 20-40hz zone in my classical collection where i feel there is no loss missing these few  rare notations. 
Caveat here is employing high quality Mundorf caps to acheive this extra punch from the W18E001 Excel. These caps are not cheap. 
Troels also mentions, high quality speakers deserve high quality caps.

"There are trade-offs with either approach. Matching YOUR needs and preferences should take priority".

Agree 100% David.
With this speaker I'd prefer tubes (I just like what tubes do). However no question that there has been much success reported by those who have chosen solid state amplifiers. Superb outcomes are possible with either.

I can agree with this assessment. 
But as with you, I prefer employing tubes. 
a High quality tube amp , on the used market can be had for under $1500, I just don't think there are ss amps under $1500 that can compete. 
I see tubes as the wave of the future. 

ricevs673 posts06-01-2021 3:04pmThe standard Cube Nenuphar retails for $15.9K......as far as I can see. The drivers list for 6690 Euros ($8176 USD) the pair plus shipping and duty. The mini retails for $12.0K.

OK so we have  some vital important info, which i could not find on the Inet.
I would say the speaker/driver looks interesting, but not when I compare Cube to my 1st choice in **Full* Range* which is the Voxativ line.
Should be September when i add the Vox AC1A's. 
I will build the cabinet , using sanded ply from HD, cost of material,,,,under $100. Will take me 6 hours/or less to build. 
Weight each cabinet = 30 lbs +/- 5 lbs. 
The Vox will be for entire midrange, Seas W18 Excel as bass, some type of AMT/horn for ultra highs 10k+hz range. 
Basically it will be a  3 way. 
xover points will overlap. I have no idea how low/high the Vox voices. 
That is to say, if it does roll off either end of the spectrum, no big deal, as i have  both end spectrum handled by other speakers.
