I was looking at Audioque subs earlier and what is the difference between copper and aluminum coiled subs. do aluminum last longer or something?
Aluminum is stronger than copper. It takes more aluminum to make something strong as steel. However copper conducts electricty ans signals better than aluminum. People are switching to aluminum cause its cheaper.
to maintain it common......Copper is better at removing or soaking up warmth than aluminum yet aluminum is better at dissipating it or doing away with it. i think it is why you spot aluminum CPU coolers with copper cores.
the aluminum voice coils will get louder than the copper coils but the sensitivity is lower.ok, say you have one hdc3 copper and hdc3 aluminum.with a 1000 watts rms or smaller amplifier the copper coils will get louder.but if you go with a larger amplifier,say 1500 watts rms or more the aluminum coils will be louder.
