Metal cabinet speakers

@kosst_amojan  

I have Genelec in aluminium cabinets and they are surprisingly inert - you tap them and you get much less noise than a mdf cabinet. The shape and thickness may play a roll - Genelec’s aren’t square and everything is smooth and rounded. Certainly the aluminium thin heat sink grills on my amp ring when touched.

Genelec still does aluminium speakers. ATC did aluminium speakers for many years. Aluminium works well but I believe it is more expensive than mdf and 3 to 4 times heavier. Impractical for anything bigger than a two way monitor due to weight.

Advantageous material for cooling of heat sinks, good damping, naturally corrosion resistant and non magnetic. My six channel amp is extruded and billet aluminium and is extremely heavy (about 50 Kg) but would be even heavier if cased in thick steel!
