@stephendunn  Congratulations and welcome! Looking forward to your impressions.

Stephendunn,

With the stated output impedance of your OTL amplifier I suspect you're going to have a very fine match with the Nenuphars. Congratulations and I look forward to your upcoming listening impressions. I believe you'll be quite pleased with what you hear.

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.
