RE: that's on the magnet pole piece, not the driver

Magnepan used/uses different methods for tuning the resonant behaviour. A rectangular driver without "buttons" need a varying tuning top-to-bottom. That can be found in some Tympani bass drivers. Others are tuned with the help of buttons that split the diaphragm into smaller sections with varying resonant behaviour. Both methods can be used together. The 3.7/3.7i have a lot of buttons.

The 20.7 have foil conductors.
