Hi guys ,

I be been on this thead on and off.I m an old owner of nenuphars( 3 yrs back)

Long story but i moved to another house, another system, another project.

i had a second pair of cube nenuphars drivers v1 wich i upraded from single driver builder in singapore ( he has his own brand), this was before cube audio make the v2.


the pair i have is v1 upgraded with different japanese paper craft .

i spend for this upgrade 1500€( incl shipping).


the specs are still the same as the v1.

i tried them on my friend nenuphars cabinets, and to my ears they sounded better than his v2 .

i was planning to make different design with these drivers, like back horn loaded, or open baffle design , but long time passed, and i m not a diy myself.

i m no longer interested to go ahead with this project and i m willing to sell these drivers to someone handy , willing to explore them, or even try on his nenuphars. 
they looks gorgeous.

if interested let me know, i will share pics, videos playing against v2 and price.

Audiophile-Magazine Review of Cube Audio Nenuphar V2 in English

Announcement from Cube Audio of the ’Grand Fission 2022’ awarded by Audiophile-Magazine AND a video with recorded music.

BTW: excellent sound quality based on a listen via my basic IEM / portable DAC/ Headamp. I'm really looking forward to listening via my primary headphone system.
