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?

@mijostyn, A D'Appoltio Array uses a 3rd order cross-over not a 6dB 1st order cross-over.
I had a set of the Celestine SL600 with the honey comb cabinets and they did some things quite well. but huge power pigs.  had an amazing midrange not so great in the extremes as modern speakers but very musical and engaging if I remember correctly.  but wow needed a lot of power to wake them up 
I have Focal CMS 40 monitors on my desk. Aluminum and very heavy. They don’t resonate and add sound/ambiance like an MDF or plywood box does.

Having said that, a resonate box can be very enjoyable. I love Harbeth and Rega mini monitors.
