Noooo! Richie replacing the bridge inserts with higher wood is not
the solution, if the cone has sunk it is because the edge that sits
on the barrel has bent upwards resulting in the center of the cone
sinking. The whole principle is that you want the cone to be able to
flex up and down just like a cone in a speaker does, when the cone
sinks due to the described condition you have taken away some of that
capability to flex up and down through a distance of travel and thus
reduced the output from that instrument. The correct fix is to
reshape the outer edge of the cone to again lower the outer lip thus
raising the center of the cone which in turn raises the center of the
spider and the bridge. This is a common problem in a lot of the
pre-war cones as they were made from a softer composition than the Q
cones, it has not been much of a problem with the Q cones.
