Dear Troels
You can find some pictures and construction details of my CNO-4 at 
«[HIFI upgrade] Salon Muscadet - Page 10» - 29974017 - sur le forum «Installations HC non dédiées» - 1215 - du site Homecinema-fr.com
It took 1 month to have loudspeakers fine. Before bass are too obvious.
My room have an acoustic treatment. The CNO-4 can sing here as high level of transparency, with such natural. Can go also in deep bass. You get what you pay for: heigh-end speaker.
I figured them with Ebony veneer because they are also with for home cinema behind the screen and must be dark.
I should really like to thank you for sharing such great speakers.
Regards,
Damien
