If you try working on the driver with a normal magnetic screwdriver, you will be fighting a very strong magnetic field that wants to suck the tool straight through the non-replaceable diaphragm. You don't need this, you need to be free to concentrate only on torque. |

Please whatever you do, do not stick in the gap anything metal. By doing it you short the gap eclectically and you are discharging the magnets. Use the only plastic or wood scrubbers not metal. (I use the tips of the cable fasteners- very continent). In fact 95% of all dirt might be handled without any tools just using marking tape, which is essential for any gap cleaning.

| One more thing you might consider... There is quite a serious Vitavox user in Italy who applies a thin film of machinists oil ("3in1" for example) to the edge of the metal diaphragm (just the edge... the part that gets clamped) and on the screw threads... He tightens the screws with a minimum of torque. The oil I assume allows sealing the diaphragm, without torquing the screws too tightly. It may also slightly damp diaphragm resonances. I have not yet tried it, but the logic appeals to me. (I need to get this guy's contact info). |

I was experimenting with it, adding between the cone and the pressing plate different soft gaskets. I did not go for liquids thought… Probably the Bud’s EnABL techniques should the next to try…
