unkonw WILSON speaker

Looks like a knock-off.

I've never ever seen Wilson use a ring radiator tweeter, or a Waveguide for that matter.

I just used Google Translate, since my French is not what it was... ever. :D

They don't call this a Wilson.  They call it a "High End Construction" which makes me believe this is a DIY project.

Look at the pictures blown up. The construction quality is way below Wilson quality for the metal parts using sheet metal and standard screws. Wilson would never do that. Plus although it copies Wilson time alignment it uses box shapes Wilson never used. It is Wilson inspired knock off but not even a copy.

Who said the speakers are Wilsons?

That would be the R2R4 model.
