Morel Tweeter Measurements and Tweaks

I have a number of Morel tweeters to work with. I first bought a used pair of MDT-30s, which were essentially unused. Later I bought a new pair of MDT-20s, and eventually three more of them used.

All of them exhibit some non-linearities from the published specifications (to be expected). I've worked with them to investigate possible reasons. These pages are the results.

I am now more impressed with the MDT-30 now. The uniformity between the two drivers is particularly surprising.
