Speaking of "blowing", I have also made the fatal-to-the-ribbon mistake of trying to gently blow a speck of dust off one of them.  Don't try this at home!

No doubt …. there's still likely to be all kinds of magnetic crap down there!

Actually the magnetic crap turned out to be not so bad. I enspected the driver carefully as sure it is some metallic dirt in there. Interesting that the way how the driver constructed it is not so difficult to remove the dust from the gap by sliding the pieces of dirt across the cheeks of the horn. In fact it is very easy. Also, the way in witch the ribbon is suspended relative to the polls those partials of metal dirt do not really affect sound in any ways. I think for this ribbon the dander is not the metal dust that the driver sucks out of air but the larger objects that might be attracted to it and will destroy the ribbon themselves whale they are flying to the polls.

Anyhow, I went to a fabric store and fond a very good material that I like a lot. It is a very fine net made from cloth but it has no hair of any kid. In fact it is plastic fabrics. It is absolutely transparent and has literally no mass. It reminds me the material the women’s stockings are made from. I bought a few yards and tossed it on the driver. It has no sonic consequences but it kind of metals isolates the driver from its environment. In fact I fell that it even looks better in context of the entire Macondo and the Water Drop’s position become less prominent visually….
