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

FWIW, Art Dudley's review is about the newer Cortese. The one I have is an older model designed by Shindo pere, Ken. There is a review and picture here at Dagogo:

Does anyone know how they differ?

"Does anyone know how they differ"?
Differences between the model generations were covered in Dudley's review.

@stephendunn  Thanks for taking the effort and time [it's a  significant undertaking] on removing the Nenuphars from the Townshend platforms and conducting the A/Bs both on and off of the platforms.

Thanks also for sharing your results and your overall preference.

For me, the platforms are a NO GO. It's unfortunate that we can't listen to each others' setups. : )

@kw6  +1 to @stephendunn 's response to your question (both copied below):

Stephen >>> "Nenuphars have ten inch drivers....those drivers deliver a ton of top end air.  Have you read reviews at 6 Moons, Stereo Times and avshowrooms among others?  They might help overcome your concerns about a single wideband driver. "

You >>> "Still concerned no tweeter not able to get top end air! What do you think?"

BTW, I just read up on the Odeon Rigoletto 2020s and they appear to be a great choice.

@abd1  You have excellent company and are in a very good place with your Alan Eaton and Primaluna amps and those tube choices at your disposal. For me, reading your post is happiness inducing. Thanks!!!
