1)      The foams from back chamber pushed itself through the window of basket and touched the driver cone. Sonically it is very likely but knowing HOW I did the thing I think (hope) it did not happen.  Also, both horns have identical impedance behavior – does it means that foam hold both diaphragms in same way?
 


I think the foam vibrates with the cone even if it is not directly touching it. And even if the damping of the foam is not the reason for the flat impedance curve there will still be non-linearities. Was the horn fully assembled when you tested it in the basement?
