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

Robert, thanks for posting this. The link above is to AVShowrooms review of the Cube Audio Nenuphar (10 inch) speaker.

If you want to hear Peter Breuninger’s closing summary it starts at the 31 minute mark.

Jon Ver Halen's discussion about the design of the driver and the speaker is very informative.

Here is the main page, that contains more information, including the review Robert links above.

A question to those of you who have been thinking about these speakers for a while. If you're supplementing with subs, is there any reason to choose cube's 10" drivers over the 8" ones?  

I haven’t heard them with subs but feel no need for them.

@toetapaudio  Thanks for the information.  If I went this direction, I'd start by just buying the driver.  Was thinking that I'd probably start with open baffle in that case and potentially copy Nelson Pass' approach ( https://www.stereophile.com/content/gramophone-dreams-26-nelson-pass-harmonic-distortion-page-2), or use the Cube drivers to replace the head units on my Coincident PREs (again in an open baffle).  I'm assuming that the drivers in free air would start dropping off substantially higher than the enclosed 30hz.  And given that I listen to quite a bit of electronica with some rap, pop, and hip-hop, I'd need to add in those lower octaves.  Essentially, that would be a diy version of the BASiS.
