This is a good example of a CNC horn. This is the Carfrae I was talking about. MDF Upperbass horns are made in sort of the same way, but you do have to cut the angles on the Lathe. (or leave the steps like a The thing is it is not really tridimensional, in a horn like way, or Like Axel says "the ever changing angles" of a horn.
Axel. "there is still PERCEIVABLE energy at ~ 3kHz" and this Glares the mid range.... If I understand correctly.
I tested my upperbass horns with no low pass and the freq. that went up to 3.5kHz also did mud up the midrange, so I had to put add a low pass at 700hz.
But the 1st order Xover fixed things pretty well IME. I expect the same would happen with the Midbass horns.
There are some similar Nagaoka BLH kits in Japan mainly for Fostex speakers.
