Metal cabinet speakers


I like the idea of a very strong inert metal cabinet. Besides Magico, Steinheim and T+A.. who else makes metal cabinet speakers?

Bad rap MAGICO dude they sold over 750 pairs of A3s as many people love lifeless sounding speakers.The reviews are great because the speakers are great!!What do you have??? 
Paradigm Persona’s are not metal. They are wood composite. 

Also, different metals have different damping factors. There are far too many variables to make any judgement on this. 
I did a tour of the YG facility and their process was super impressive, and the speakers did sound great. They CNC all their own parts/drivers/cabinets out of 2" thick aircraft grade aluminum.  No parallel surfaces, double walled cabinet construction. Apparently it takes 120 hours of CNC milling for them to make a single pair of Sonjas.
