    aluminum or copper voice coil?

    plan on getting an ssa icon and have the choice of aluminum and copper. what is the difference?

    Usually weight and power handling. In general, copper can handle more power but it weighs more. IMO, an aluminum coil sub will respond faster, sound better, but usually can't handle as much power until you get into larger coil diameters or heavier gauge windings.

    Dont more often then not, SQ oriented subs have a copper coil, therefore a lower Fs?

    aluminum coil subs usaully have a higher fs

    Fs is the resonant frequency of the driver. The Aluminum coil option is for people who are going to really abuse the driver and push it too its power limits and want a little more peak in their output.

    All things considered, copper is the superior conductor. period.

    Aluminum is cheaper

    This is the only answer.

    Re: aluminum or copper voice coil?

    if both coils are = then the alum will be louder. the copper will handle the power betterfordaily though...

    The coils are not equal in this case, so the aluminum have a little higher thermal limits.

    alum cools faster yes but why its louder is weight.

    Re: aluminum or copper voice coil?

    Aluminum cools faster but I thought part of the job for the former and the gap is to cool the coil?
    A heat conductive former will draw heat out of the coil and cooling vents for the gap, exhaust the heated air.
    Aluminum wiring in houses tends to burn, that's why they switched over sometime in the 70's for safety reasons.
    I would imagine you would have to have a lot heavier gauge aluminum to equal the power handling of copper?

    X2 MMS is a HUGE factor in efficiency.
