yes, tempting isnt it
but not so easy at all
for one, bigger drivers are usually built for higher power handling, and less aimed lower frequency
for hifi you dont need the huge powerhandling, and thus its possible to cross lower
but dont forget you need a much bigger waveguide
and its getting a lot more expencive
another problem could the transition to a big woofer
two drivers with totally different sound character
cannot be easy I guess
is it worth it ? I dont know, maybe it is
but surely, just crossing low is not all there is to it
Mating issues are there regardless. Only get better by crssing to 6-8" mid. None of those go far and niw you have multiple xo points. Ill try two way and go from there. So many people prefer bigger throat sound over 1"
If I go Iwata, I may try 500-600. Cant tell until it begins. found a couple interesting sites i case you are interested.
Are Iwata horns that good?
Yuichi's Audio Lab.
L'ébéniste audiophile
Iwata horn - Audio Voice Acoustics
Second one is the most interesting with more explanations. I really like the finned versions. I could pull this off as I am a bit of a woodwroker, but i still have interest inthe LeCleach versions as well.

nice looking driver, but response seems a bit bumpy
but maybe thats normal, i dont know
also most of the big waveguides appear to have a bit rough upper frequency
I wouldnt mind trying it myself tho
too risky for me, but if it sound like the HF100, Im in 😀
wow, thats cool
I didnt know my own waveguide was a Iwata profile
or at least a 'look alike'
no wonder it sounds so good 🙂

Q could be part of it, of course. I really don't know "why", it just a subjective impression that I've gotten on a lot of different systems. Active can sound a bit hyper-realistic to me. So detailed it sounds better than real. Like peering at the music thru a microscope. Very impressive, to be sure, but a good passive crossovers seem more organic, more natural to my ears. That sounds like pure woo-woo, I know - but that's how I hear it! 😀
(Active subs are a different matter).
Where do you cross the HF100 in? They say it should be 2Khz but it dips nicely to 1khz at 100db/w/m - do you think you could use that to mate nicely with the 15FH100 at 1khz?
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 that´s 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.

HAHAHAHAHA!! The local rep for Auto-Tech is a 20 min drive from me. Am trying to arrange demo. Will take pix if allowed and feedback next week
Seeing him monday!
heres some pix I found to wet the appetite
To me the first pic of the E-JMLC-300 looks like a triffid that might swallow you whole if you talk while its playing! Im liking the JMLC-400.........
