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

At many audio shows, the Zu Audio room features their models playing hard rock and metal music playing at extremely high volume.  The speakers are quite capable at delivering at high volume levels.

Full range single driver systems cannot deliver that kind of volume level (the Nenuphars delivered plenty volume for my particular taste) and actually excel at delivering a vibrant sound at quite low volume levels.  Although they are not particularly efficient, they are probably efficient enough for use with some SET amplifiers if one does not demand extreme volume output or use in a very large room.  

Use with a single-ended 300B amp?  I don't know, I never heard them used with that kind of amplifier.  But, I guess they are not well suited for smaller single-ended amps, like those running 45s, given my experience with a 99 db/w 8ohm speaker (I've run this speaker with pushpull 45s, parallel SET 2a3s and pushpull 349s; single ended 45s were okay, but marginal with certain kinds of music).

The OP of this thread david_ten uses the Found Music 2A3 SET mono blocks with stellar performance results. No doubt room size and ultimate listening levels are variables.  Cube Audio pairs the Nenuphar with 45 and 2A3 SET amplifiers (Usually Tektron brand) at audio shows throughout Europe.  These pairings consistently receive high praise.

@abd1 Congratulations on acquiring your Canary M90 amp. How soon will you receive your Nenuphar Minis?

Any Nenuphar owners in NC, Virginia, SC or Georgia?  I’m really interested, but need to hear them in person before making a decision.  Of course I’ll wear a mask.  Thanks,

@david_ten The speakers are supposed to arrive early-mid December. At least to the distributor. So I'm hoping to have them mid-late December. I'm very excited. So far I'm using the amp with my 85db standmounts and it has zero issues driving them. It's a push pull 300b creating 26wpc/8ohm. It does help that I'm using a pair of REL T5i's for the bass, but this amp is far from wimpy. I was lucky that the unit I purchased came with some nice tubes already. Vocals are so lifelike with this amp. Midrange is gorgeous as well. Its pretty dead quiet and effortless. My wife said this combo I'm using sounds so good why do I need new speakers. It does sound really good, but can't wait for her to hear the Nenuphar Minis. I'm planning on starting out w/o the subs. I don't think I'll need them with the Minis, but I've been really impressed with these subs and I generally don't use subs with 2-channel.
