Metal cabinet speakers

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.

@shadorne stated Genelec does make many different models out of aluminum. I own a pair of Genelec 8350A's that I adore. The use of metal also allows for speaker designers to work with a material of great rigidity. The cooling effect is also a plus. On the con side, cost and weight.

Karl Shuemann who used to frequently offer valuable posts here on Audiogon before opening his AudioMachina line, has made some very interesting speakers, some of which use metal cabinets.

Add Piega and Burmester to the list.
