I might go Linwitz still, Decision is not entirely made yet but .... I like Geddes philosophy and the Science -based approach he used. He's unfortunately out of the speaker-building business ...I was tempted to build the Geddes and Linkwitz designs, but, realizing how difficult, time-consuming, and (crucially for me in Manhattan) space-consuming either of those construction processes would be, I threw in the towel and decided to buy the D&D 8Cs. No regrets.
The 8C + Subs remains asomething I would love to audition .. Still... SO many choices these dyas for SOTA speakers.
@Shadrach.
There is a person on this site who's built a speaker based on the Dutch and Dutch 8C. PM him to know what it entails to build such a speaker.
