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

BTW I should make clear that my previous post regarding sub woofing the Nens is not meant to be a blanket recommendation to do same.  My set up puts the speakers far from corners, sidewalls and front wall (to emphasize breadth and depth of soundstage) and my ceiling height is over 20'.  So there is little ambient base reinforcement which accounts for the KEF KC62 making a more positive impact than it might in another set up.  And I meant 60Hz not 60db for crossover.

Is anybody using a SET 300B amp (~8W) on the Nenuphar listening to large orchestral classical music? 

Is that expected to work well in a 12x18ft room (4mx6m)?

@mga71 I believe I’ve posted on this before (if memory serves). IF NOT, here goes:

With this version* of the F10 Neo drivers: it is my opinion, based on two and a half years of personal experience, that the power output from a 300B SET amp is in the "ideal range" to drive the Nenuphars (F10 Neo + TQWT enclosure).

I continue to be surprised that owners have not used 300B SET amps to drive the Nenuphars. Even if I ignore [IMO] the "ideal power output synergy", the far wider numbers and brand options available (versus other SET types), the spread of options over a wide price range, the healthy used market, all point to a higher probability match.

My previous 2A3s were purposely designed to output 4 Watts. My current 2A3s are purposely designed to output 3 Watts. In both cases, my percentage of large scale orchestral music listening has increased. Note: this is also due to and dependent of other system based changes.

My room is 19 ft wide (front wall) by 26 ft long by 9 ft tall.

Given what I’m hearing across a fairly wide range of music genres, for my preferences and needs AND room size, I would not want to go below 3 Watts. Again, this is for a very wide range of genres. If someone is focused on smaller scale acoustic genres, then lower output power will be fine.

I want to make clear that the Nenuphar driver and enclosure design has limitations, specific to it. As does any speaker design. For illustration purposes, a large scale multi-driver speaker will deliver aspects related to large scale orchestral music that will fall short with the Nenuphars. On the other hand, the Nenuphars will deliver in areas those speakers fall short in.

I used sophia electric 91-01 monoblock 300b SETs with my Nenuphar Mini’s. Sounded fantastic. Plenty of output. Great detail, texture and very controlled, nuanced bass. I’m actually selling the amps however not because they were lacking in any way. Just that we moved and have some house projects to take care of and I need to sell some gear. I also have some hardly used Takatsuki 300b’s that take everything up a few notches.
