I do not think it is correct. The rotation of electrical phase is not the subject of filtration method but subject of slop and Q. Of you write the same Q by electrical, acoustic, digital or mechanic ways then you have the same phase shift. A horn, when it does low-pass filtration due to horn death, introduce the same phase shift as your electrical coil would do. This all well described in literature. Anyhow, I am not sure if it all has any practical interest. I myself is much more empirical way person and since I know that you do not deal with horns and discuss it only as theoretical exercise I am not sure what we are talking about. It does not mean that I disrespect what you are saying but I also do feel that some aspects you bring up has very little practical significant, at least among what I have tried. Do not forget that compression drivers have one suspension, there is no internal spider like in your drivers. This makes the games very different. I think University driver has a compression drive with 6” diaphragm and second inner suspension, it was a model M4. It was a horribly sounding driver…
