Thing is, a particuar coil is tailored to its speaker so whatever field it produces is adequate PROVIDED the current through it, which is dictated amongst other things by load and applied voltage is what it was designed for.
Also less rsistance does not necessarily mean less field as there might simply be a thicker gauge wire used, and again, the magnetic field, or magnetomotive force is plainly speaking Amp-turns, which means that if you have half the turns and twice the current, your field remains the same.
