The Function One horn is quite unique because it can play pretty low and got a quite good dispersion control down low. There are very few horns directly comparable to them. If the 8" and 1" of the coax 870 are too small, an alternative could be the Limmer 308 Horn - 12" 1,5" 60° x 40°. Not exactly cheap and it doesn't have the same good dispersion control down low but it would match the spl performance of the FO EVO6SH.
E: The Limmer 312 is the same without the tweeter horn.
