When changing diaphragms in most drivers the new diaphragm may not be 100 % concentric to the old one, and the only way to align it in the magnetic gap is by removing the iron pole from the driver and loosening the screws holding the center pole piece, then and only then the diaphragm can be aligned with the center pole piece and rubbing or touching of the voice coil with the pole pieces in the gap is avoided, this may happen at certain frequencies only, producing a very harsh sound, even passing a static or a dc diaphragm test , therefore the claim that the diaphragms are replaceable in the field is not in many cases true, only when the driver has adjustable screw and dowel locating pin the alignment is possible without getting inside the driver and when alignment of the diaphragm is needed, the plate holding the pole pieces and assembly needs removal, by doing so the pole piece may be well set and aligned but the magnetic field will weaken significantly by such a procedure and solving one problem leads to another one, in this case the driver needs to be re magnetized in order to perform well.
