Metal cabinet speakers

You missed YG Acoustics, who make heroic metal cabinets.

Wilson Benesch has metal and carbon fiber cabinets. Very low noise

It has been out of production for ages, but don't forget the Celestion SL600 in Aerolam.

Agree with @millercarbon in part. What I’d add is that a carefully designed wood cabinet could be better than metal, but open baffle speakers are really the way to go IMO for several reasons and he touches on one important one that relates to metal.

Magicos are the most lifeless sounding expensive speakers I've ever heard. The idea of making a ringing speaker is hideously dim. The idea of paying writers to tout them obviously not so dim.
