" I've never seen before and after measurements".
I seem to recall tnat one of the UK magazines did publish before and after break-in measurements for one loudspeakers in a test run (I think) by Keith Howard. That would indicate the magazine to have been Hi-Fi Answers and the date, maybe 35 years ago.
The test did reveal some small differences, I think related to the spider. However available materials and techniques have improved substantially over the intervening years so what may once have been a common requirement may no longer be so. A bit like motor cars. When I was a boy sixty years ago I would commonly see cars pootling along the road with a sign in the back window reading " Running In , Please Pass". In those days a new car was limited to low speed running for the first few hundred miles as it was not then possible to machine to the degree of accuracy now commonplace. Hence that final degree was achieved basically through wear of adjacent parts. It's no longer necessary to do this. Could that also be the case for modern speakers?
