Good results Andrew. Thank you for sharing.

Any chance we could see your on-axis curves for the various states?

Hi Dave.
I don't have the data available. I did it back in the days at KEF on the 2pi baffle.
I might be able to find some other 4pi measurements of recent drivers where I have been trying to investigate response peaks by pulling off the dustcaps. As you have been pointing out, this is often fruitless because the issues are mainly from the cone, not the dustcap!
I concluded that given this, it is often a good idea to use a small diameter rigid dustcap bonded directly to the voice coil former to help stiffen the former.
