It doesn't really matter how you conceptualize the taper for Hornresp to model it accurately. As long as the horn can be described within the constraints of Hornresp, you will get a good prediction of performance. As an example, you can enter a schematic of a pipe with more flare in the first section than the second. You could even model a horn with negative flare in the first section. This would be similar to a horn with two front chambers, the one between cone and throat and a second from throat to restriction through negative flare. So there are many shapes that can be described with Hornresp beyond the usual simple shapes.
