my HF100 is the old one
from memory its more like the HF102, a bit round and rolled off
the new revised model should be able to go lower
but maybe the low ressonance peak is lowest possible xo point
but I dont know

hmm, right now its a 6.8uf cap looking into 15ohm series resitor, then some inductors and resitors in paralel, and a very small series inductor looking into a small resistor
its probably not crossed very low, maybe just below 2khz, like maybe 1.7khz, but I really dont know

that said, I did put a lot of work into making the throat transistion smooth as possible
CD exit angle ? I dont see there could be much to do about it

I just want to hear the polymer diaphram. It sounds like it has the potential to maintain clarity, but be smoother like BE diaphram is said to do.

I doubt this is a driver you'd want to cross at 1K. It might "work", but would it sound good? I don't think it would.

I prefer to x-over a bit higher, think it sounds better when the lf unit covers the fundamentals in voices, but thatīs just an opinion.

If You can accept 1.7kHz or up a bit then the STH tractrix horn is really nice, very well built and cheap.
