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

@mikeg Mike, the same questions came to mind when I saw the specs over at Cube Audio.

First thought was a typo (i.e 28 Hz)..I would have minimally expected 30 Hz (6dB)...a slight gain in LF. This is especially puzzling given what Cube highlighted regarding the V2 version:

"You can expect it now to be have even more bass"

@vinpic Any thoughts, given you have the V2 Nenuphars?

I have sent Grzegorz an email requesting clarification.

Heard back from Grzegorz. It was a typo: 28 Hz (6dB) is correct!!!

They will make the correction on their webpage.

I’ve deleted the former post. Here it is, with the [single correction]. If there are others, I will repost.

Specs for the V2 Nenuphars from Cube Audio:

Parameters:

​​Impedance: 8 Ohm

Max power: 40 W

Efficiency: 91 dB

Frequency response: 28 Hz - 18kHz ( 6db)*

​Dimensions:  30 x 50 x 105 cm

Weight: 40 Kg ​​

* Frequency response may vary and depends on room size and accompanying electronic equipment.

A typo indeed.  V2 covers a wider frequency range (lower & higher with a slightly more balanced mid-range if you ask me).  I don’t have a lot of direct experience of the new bass extension as I use Cube’s V2 10’’ monitors and complement with their Sub12’’ 

@vinpic 

Yes, I think the Cube Audio sub is the next step, although I'm thinking of the 10" since my room is slightly smaller than yours.  Right now I'm using a KEF KC62--a mini sub that does a credible job.

I prefer both the Enleum and the Zen Triode without a pre.  

I'm not tempted to try mono block Zen Triodes since 1) I don't feel the single Zen needs more head room--although the monos might offer other benefits as well, just twice as many tubes to maintain 2) I think the Enleum may end up in the system the lion's share of the time. It plays better at lower volumes than the Zen, although that might have more to do with controlling volume through the TotalDAC instead of the Zen dual volume controls.  I'll have to experiment.  

I sent the iFi Pro iDSD back--a great a value but fell short of the TotalDAC D-1 Dual.
