But there is a mechanism which could make it so in practice. Any DC offset will move the operating domain of the voice coil to a different position in the drive unit. No drive unit is perfectly linear over its operating range (variations in the magnetic field, changes in cone suspension compliance, etc), and this could conceivably cause an audible difference.
