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

I've spent my recent free time on motorcycle research, demos, etc. Time to catch up on the thread!

@ricardoosusa   PM me if you would like to connect over the phone. There are a lot of questions in your post and it will be much more efficient to cover them over a phone. 

So the Nenuphars seems to me like a great option to an all tube system. Being someone who doesn’t like complex systems and much prefer simplicity and short path to signal, no subwoofer its a must for me. The questions I have would be, how good are the high frequency? Describe if possible. How good is bass on a medium room say 14 x 18 ? Is it deep and able to energize it ? At what volumes? Do they play fast and accurately when demanded? Do they present a neutral and balanced sound or lean towards other spectrums? I appreciate if owners report in with valuable insight of these marvels of modern sound reproduction.

@ricardoosusa   Regarding your room size...it's also important to consider the type of room you have. Can you share more specific details beyond the size (14X18)?

@paullb   Paul, did Charles' response address your question? Let us know.

@debjit_g There are so many factors in play. In other words, guidance and results may (and will) differ and vary.

Speaker positioning is a deliberate art form. You will be rewarded immensely by getting it ’right’ with respect to the Nenuphar and your room. In your case, you also have the amplifier pairing in play.

The person who helped me set them up described the "interface" as being "eutectic" with the room. [Search for Eutectic Composition and Point]. I found the ’descriptor / concept’ very helpful in moving my understanding forward.

My room is 19 by 26 with non-symmetrical aspects. For example, from my seating position, there is a large ’doorway’ in the front right corner and a very large pass through into the kitchen in line from my right shoulder all the way to the right back of the room. Perspective is from the listening position, facing my speakers.

For reference, here is a link to more information on my room:

As for the amplifier, I’m beyond pleased with the synergy and performance via my 2A3 amps and their 3.5 watts per channel. I’ve invested in pushing the 2A3 envelope even further with a custom build which is under construction. This new build is focused on maximizing sound quality (not power) so 3 watts or slightly less in terms of max power output. 

Hi @ prof,
Ironically the owners of the Nenuphars and professional reviewers point out it’s the ’lack’ of a "Lowther" shout/signature that draws them to the speakers (Amongst other sonic characteristics). It seems that actual listening experiences may be the vital factor that shapes an impression
