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

I've been researching the Nenuphar Mini's for a few weeks. Given that there's no way for me to audition them, I have been mainly gathering data from youtube videos and forums like this. Frankly, the more I read, the more confused I get :)

Some people claim they are not easy to work with, requiring very specific amplification and being very fussy with placement. I've also heard that the bass is anemic. Yet, there are many who claim they're the best speakers they've owned regardless of price or pedigree.

In other words, there doesn't seem to be a consensus, which should not be surprising to most seasoned audiophiles, haha!

My question: how well will they do with Audio Research Reference 250 mono blocks. Here are the specs for the amp:

• Input Impedance: 200k ohms (balanced)
• Output Taps: 4, 8, and 16 ohms
• Output Regulation: Approximately 0.9dB 16 ohm load to open circuit (Damping factor approximately 10)
• Overall Negative Feedback: 8.8dB
• Input Sensitivity: 2.4V RMS Balanced for rated output (25.5 dB gain into 8 ohms)
• Power Output: 250 watts per channel continuous from 20Hz to 20kHz
• Frequency Response: 0.5Hz to 110kHz, -3dB with 1W output
• Power Bandwidth: 5Hz to 70kHz, -3dB

My room is roughly 20x15 with 11 foot ceilings. I do have a pair of subs to augment the lower frequencies.

Any feedback is greatly appreciated.

I really appreciate the detailed responses and the video link to my initial query. There's no doubt that this is a very good speaker, however, doesn't seem to be a good fit for my amps. Based on what I'm reading, it will most likely result in overdamping. Secondly, my concerns about the Neunephars being not the easiest to position are also somewhat confirmed by the responses.

I've also talked to some owners and sounds like resale is perhaps below average. I do see several used Cube Audio speakers going for less than 50% and still not moving. Of course, this does not mean they're less than stellar, but the fact remains that buying without first auditioning in my system is a risky endeavor -- especially, given the speakers are highly dependent on amp pairing. I don't want to go down the flea watt amp route at this time.

Having said that, I do want to explore speakers which are not your typical multiple dynamic cone drivers in an inert cabinet. Nothing wrong with that of course, but I'm kinda bored with the same old same old. I really like my Magnepan 3.7i speakers but they have several deficiencies that are hard to live with long term. I'm going to explore omni-directional -- MBLs or German Physiks as my next step. Again, thank you for taking the time to respond to my question.
