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?
@verdantaudio Have you heard the Magico M2? It has 1 piece carbon fiber cabinet. Sounded amazing to me. 

Also the graphene drivers on the newer magicos are awesome.
@smodtactical  I have not heard the Magico M2 but have hear lower end products in Magico's line.  I have supreme confidence that it is spectacular.  

I saw that SEAS is offering Graphene coatings on their drivers.  I will make a point to listen to them at Capital Audiofest.  

My design is pretty good and for stand-mounts I am confident I can go toe-to-toe with anyone.  It will be interesting to see how my designs stack up against the S1 MK2 and the Sabrina when I introduce them.  

Hello All,

Much of what has been discussed so far in this thread can also be found in a similar related thread on Audiogon started back on 5/25/18 by Vinny55:
“Which material sounds better for speakers construction? Wood, Ply or MDF?”

i noted in more specific detail on that thread, more than I am here, about how and why Paradigm’s Persona Speakers use 7 Layers of High Density Fiberboard (HDF) with internal cross-sectioning of Marine Fiberboard.  I suggest referring to that thread for many similar points made about cabinet construction in this thread as many things will get restated here that you can find there.

Thrax Audio Lyra, Aluminium cabinets, they sound great when set up right.
