I'm confused, the last photo in the first set of photos posted in this thread shows that the side of the pole piece that faces the cone has a narrow slot aperture.
In the last set of photos posted you can see the underneath of the same pole piece, it shows a wide slot aperture underneath, that's the side that faces away from the cone?
