Dunlavy SC IV extra tweeter felt?

My Dunlavys have 4 diamond shaped pieces of felt over the tweeter, unlike the other models. Anyone seen this or know why

They do not cover the dome of the tweeter. I have never seen this on any other SC-IV (or a pair of III's I had).

My comments were just to try and make sense of the OP's speakers. I thought that since Dunlavy was no longer in business, people may have had a hard time getting replacement parts. Since no one can find an instance where felt was applied directly to the driver, it was my guess that someone would do this to "tune" a close match, that was not a direct placement. I could be wrong on this. It just seemed like the most likely explanation.
