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

+1 @debjit_g   

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 :-)

@debjit_g You are welcome.

For me, the two week downtime (which is mainly due to shipping the drivers back and forth) is about as reasonable as it gets.

Jon will only proceed once he has the new driver materials on hand for each request.

I spoke with Jon yesterday. He should have his ears on the new drivers soon and will be able to provide his feedback on differences, etc.

@david_ten yes, I agree. It’s quiet a reasonable time give the situation we are all in. However, since Covid many of us are WFH and enjoys listening more than ever :-)
