[QUOTE="Haunz, post: 7086146, member: 576010"] We obviously can't make two coils using different materials the same.. so this time try to forget about DCR... The aspect I bring to the table is based on performance considering identical mass and wattage (and not DCR per say)... so lets try an aluminum coil with a corresponding larger dia. wire and overall O.D. for the same mass and wind height and see which handles more power and has the better sensitivity... I must admit that aluminum has some advantages for SPL burping being light weight, and with it's [I]gram for gram heat capacity[/I].. but copper is clearly the better conductor, and is much more suited to playing music / overall abuse....
