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

With the “many”  owner feedback comments and reviews, this is the first time I have read the Nenuphars described as “shouty “ and forward.

Hi Charles, @gavin1977 statement referred specifically to the F10 Select driver which is used in the Jazzon. The Nenuphar uses the F10 Neo driver, which has a quite different magnet assembly.

Could be that he intended the comment toward both drivers. Having owned Nenuphars for over a year and experienced the break-in and associated system-optimization learning curve, I can see where someone new to these crossover-less full-range speakers could form this impression IF the drivers are not fully broken-in OR IF the accompanying system is not sorted OR IF the toe-in is incorrect.

These speakers provide little cushion for mismatched components (especially regarding amplifiers), suboptimal setup, etc, and they produce tremendous energy across the frequency spectrum (no crossover to dumb down the dynamics of the incoming signal through parasitic loss), so ancillary components with a hot upper midrange can be problematic. However, getting these things sorted delivers a sound that is so fundamentally right that, for me, it is nigh impossible to imagine returning to standard multi-driver “crossover-ed” speakers.

Fully agree with the feedback regarding optimised chain of electronics - something I have experience with. The amplifiers being used here are the ones with a proven synergy.

Jazzon:

What I’m hearing is the above frequency response. Dip in lower mid-bass, then a rising frequency response - this tilted up frequency response means I end up trying to compensate with the volume control for the lack of mid-bass, which just makes vocals even more shouty.

Perhaps the Nenuphars don’t have this issue as much:

But I can’t say that I heard them as sounding completely flat either.

I wonder if I should have taken the time to hear the F8, which is a very flat frequency response.

Just trying to troubleshoot, as there’s real promise here and so don’t want to admit defeat just for the sake of a lack of optimisation.

vs lii audio ??????? vs audo nirvana????????

@gavin1977 that frequency response curve for the Nenuphars is for the V1 version. Changes in cone configuration in the V2 version largely addressed what you describe (has a fuller midbass and less upper midrange rise). Yet, IME the V2 is still sensitive to toe-in much as the multiple lines on the V1 graph indicate.

Haven’t heard the Jazzon in person, but, as you say, its graph looks to support your experience, at least at whatever toe-in was used for that single line. It would be informative to see the graph at different toe-ins for the Jazzon. My bet, based on working with the Nenuphars, is that room placement/room treatment/toe-in optimization should go a long way toward improving the peaks and valleys shown with the Jazzon.
