Personally, I don't see anything special in the cabinet they use.  They don't even mention cabinet construction, material, damping or tweaking or their site.  Basically, its just a TQWT (tapered quarter wave tube) box.  Very good, I am sure.  Its pretty well known how to make a TQWT enclosure for any driver.  I bet they did try a few versions and damping inside before deciding on the final one.  Always more work then you think.  Here is a link to the cube suggestion for their driver.  The Nenuphar cabinet,  I bet, is not much different.  You notice they suggest just 22mm (7/8th inch) plywood or MDF as material.

Look at Magico, Wilson, VSA, speakers using granite cabinets, YG Acoustics,  Rockport, etc......now these are serious cabinets.


@david_ten Yes and big thanks. They were helpful. I am going to auditon them soon (first time didn't really do critical listening as I wanted to see something else). 

My Coincident Super Victory IIIs will really need a strong speaker to fall out of love with another speakers..but history has proven that it can happen with audio gear 😀

I will report back with my impressions. It will be paired with XA25 and Bakoon amp for the auditon. 

One thing to note for me, if I do go for the Cubes, the quest to find the right amplifier will soon have to start for me. My Moon amp will not cut it with the Cubes, that I am sure...
@sim_audio_nerd  Thanks for the update. Looking forward to hearing more about your "impressions" and your comparative take (between the two amps AND versus your current system chain) from the audition.
