RE: It is also inherent in the panel shape

Jerker (JLindborg) has given me some more insight information. I have to correct myself about the way the Apogee bass is working, the patent is not very clear on some points.

The bass diaphragm is tensioned, heavily tensioned in one direction, across the short dimension, with the help of springs. The springs are there to take up any variations caused by temperature, ageing etc., not to introduce a suspension. This is also a reason to why the panel can warp with time. As the diaphragm is corrugated in the other direction (top-to-toe), it can move rather freely. The tuning is held by the springs, giving some stiffness across the diaphragm. The damping strips of soft foam around the edge also let the diaphragm move a bit. Unfortunatley, the foam use to detoriate.
