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?

 kalali Magico is priced to attract audiophiles who equate cost as much as any other performance aspect they are well made well-designed loudspeakers for sure but overpriced like most all high-end today.         And maybe you missed this part of my post above { More to the design of a loudspeaker than cabinet materials I think focusing on such while overlooking the whole is self-defeating}

Given that I compete with Magico and offer a $7000 pair of carbon fiber stand-mount speakers, I have minimal interest in defending them but will say that there is a big difference between a 1/16" press forged cabinet vs one made from 3/8" extruded aluminum.  You also have to consider fixed tool and die costs in both cases compared to any wood material be it MDF, Baltic Birch or African Rosewood.  

I would love to say Magico is overpriced but other than retail margin, I can't see an issue with their pricing and they don't build in the monstrous margins that some other companies do. I looked a producing a speaker like the A1 and I can't do it at a lower price unless I want to produce them and import them by the container from the far east and I have to outlay a lot of cash up front for tooling. 

Regarding my costs on Baltic Birch, you can get panels a little cheaper than what you see at retail from people who are buying at wholesale in large quantities.  And for the size speaker I am talking about, you can get 2 speakers (one pair) out of a 2' x 8' sheet.  That is where the $40 came from.

9”w x 15”h x 12”d with one internal brace.   I taper mine from the 9” from to a 6” back.  There is virtually no waste but this is a pretty typical cabinet size with an internal volume of ~.45 cu ft. Though it varies slightly depending on the size of the port needed. 
Is a big potential disadvantage of metal speakers like magico q7 or yg sonja that if there is any loose bolt, nut or screw it could rattle in the cabinet ?
