Hi.
The top picture of a cut JBL unit shows it has a ring just below the magnetic gap connecting the central polepiece and the front plate.
Although there still is a little ring shaped cavity with a triangular cross section, the large cavity is hereby sealed of from interacting with the speach coil, the dipragm and the excit of the driver as well.
If I remember corectly from your pictures of the disassembeled Vitavox S2, it does not have this ring, and therfore the large inside cavity where you would place a fieldcoil, could have a significant role to play in the sound of the driver.
Who knows, maybe this accidentially placed reverberation chamber is responsible for the reportedly magical sound of the Vitavox S2?
