Hello Angelo,
About what I called "rear cavity":
Behind the diaphragm of the Community M200 there is a (closed?) chamber, you can see it on the drawing in the pdf document. This cavity is quite small and possess a quasi rectangular axial section. I don't know if it is damped.
About suspension material:
Polyester films (under the trademark Mylar by example)is the favored material. They cab be found in different thickness and eventually reinforced by fibers (Dacron...).
The image of the "poor air" squeezed inside the compression volume between the diaphragm and the phase plug is often used by detractors of compression drivers who promote the direct radiating loudspeakers. Bad compression drivers can for true exhibit resonances in relation with the compression chamber, the phase plug slits, the air volume directly in relation with the coil, etc...
When the compression volume and the phase plug are well designed those parasitic resonances are not audible and there is virtually no negative point to the use of compression drivers if they are used on good quasi infinite horns.
Best regards from Paris,
Jean-Michel Le CLéac'h
