To answer Louder's question - they've always sounded fine to me, I've never checked them in this way until now.



So, how would I use the air supply to hunt for it? Is the idea to shoot it at the diaphragm, pushing it out, whilst looking closely at the surround pleats? (perhaps augmented by shining a light from behind it?)

If the point is to get the pleats 'stretched' in one direction, I could do the same with low voltage DC while it sits in the gap on the driver - unless that'd be detrimental?
Wow!

You are about to destroy those precious diaphragms.

You don't want to use compressed air to clean out parts of the driver if your diaphragms are still installed ( frankly I'm astounded you could even think that was somehow appropriate ).
