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

@onsionsi 

Thanks for posting review of Enleum 23R as headphone amp.

Here's a review with detailed analysis of Enleum driving SoundKaos speakers:

What a creative concept! They do resemble flowers. Single-driver designs fascinate me, but there aren't any to try out around here. However, I appreciate hearing about other people's experiences. These are particularly fascinating.

Thank you @stephendunn for posting this link.

I spoke with the US distributor and it looks like the v2 driver upgrade is changing out the cone and assembly on the same frame/magnet of the v1 drivers.

The 'downtime' is about two weeks. Jon Ver Halen / Refined Audio will send a box for the V1 drivers to be shipped to him; he replaces the front of the driver and ships the now V2 driver back to you with a sticker labelling it as V2 and additional stickers for the owner to place on the outside (e.g. by the binding posts) of each speaker to signify the speakers are V2s.

@david_ten thanks for the details. I did not enquire about the downtime since I wanted to get his opinions on the v2 before upgrading and he was still expecting the shipment of the assembly. The 2 weeks downtime seems a lot, especially if you don’t have a back up speaker and you listen almost everyday. I can’t seem to think I will be out of music for 2 weeks. Cube should have figured a better plan :-)
