This chassis is the standard PSL 320 / 400, but it has been subjected to a special treatment by Guido J. Wasser. Here the magnet and the membrane have been significantly modified. This special model was used in some loudspeaker projects. This includes, among other things, the SARDEC CH-2 and CH-3. The single chassis was sold at that time for about 1000,- DM.
A short description of this chassis is also available here with kind permission:
