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

@sim_audio_nerd  Thanks for the update. Looking forward to hearing more about your "impressions" and your comparative take (between the two amps AND versus your current system chain) from the audition. 

@david_ten I auditioned the Cubes. I will post my thoughts soon. 

sim_audio_nerd,
Looking forward to your listening impressions.

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.
