Not so. Dust will not build up in the voicecoil gap as the oscillations of the cone produce a pumping, bellows like effect blowing air back and forth through the coil area.
Dust accumulating on the cone surface can be brushed off carefully with a soft paintbrush or makeup brush. Use of compressed air is not a good idea.
It is impossible for anything digital to sound analogue, because it isn't analogue!
