The magnet structure returns. Now with basket fitting holes and pins for alignment.
Looking into a future prototype, I would like to recess the magnets into the front
and back plates by a very small amount (maybe 0.5mm - 1mm).
Spoke to an extremely helpful gentlemen who is the technical contact for a plastics company. They produce (sell?) kapton sheets
and various other custom bobbins/formers for loudspeakers (including for B&W and Celestion I think he mentioned). He's going to kindly
donate a former that is 30.9mm in diamater (this one is designed for B&W) that should fit into my air gap. It's not the ideal size (30.5mm outside diameter is the requirement), but
it's a starting place nonetheless. I will probably end up rolling some plastic/kapton to the desired diameter.
