Splitting hairs is what transducer engineers and loudspeaker designers do. It's how we make our living. Current is moot. What causes a cone to move is voltage. Unless you have a transconductance amplifier you can't increase current to realize more output, you increase voltage. Magnet size affects sensitivity, but so does coil gap, Mms, Qts, Cms, Le and more. So yes, it can be done with magnets, but by no means is it all done with magnets. For every driver with a given size magnet there's a lower sensitivity driver with a larger magnet and a higher sensitivity driver with a smaller magnet.
