In the Thread: The absolutely “best” material for horns construction.

Sure, contemporary polymer concrete can be made suitable for speaker enclosures or horns. Its biggest sonic benefit is that the material itself is fairly non-resonant. It's just a bitch for a DIYer to make one after another while experimenting with shapes and sizes, at least as bad in this way as turned horns. A big problem for speaker "manufacurers", who - one supposes - have made final decisions on shapes and sizes, is that the stuff is HEAVY, at least it is if it's going to damp resonances. And heavy stuff costs extra to deal with, at every stage along the way. This would appear to limit this material to "the high-end market", which market (and marketing) has broken any number of asprirants. More likely are the Oswald's Mill type horns, which either ignore or feature self resonance. Don't know if you've seen/read the Jessie Dazzle thread, on the horn board, but if not, it's worth a look.
