"Firstly, it's "input", not "input's""
Given the diversity of responses, it seemed like the plural captured the result better.
"Some of us "get" your shameless self-promotion. Others don't."
I don't get your angle here, at work, we don't market or build products for home hifi, that's my hobby along with DIY.
A fellow I work with is into single ended triode amplifiers and he was very encouraging so far as following this idea into a prototype, the issue was size and this is the only high efficiency forum in know of and seemed like a logical place to ask.
"Why?"
Why not?
"What exactly is a "more exponential horn""
At work, most horns have to be constant directivity types which have straight or nearly straight walls. In the home, curved wall horns like exponential horns are ok because the seating area is small.
"What calculations or measurements have you made?"
I have measured the drivers electro acoustic properties and used that for a computer model like I use for work projects. As I explained, I have not built the horn yet and was trying to zero in on a size.
"Full range? Really, you're kidding, right?"
No, not kidding or at least full range down to 140-200Hz.
"Here's my advice: Call John Meyer at www.meyersound.com, and LEARN from him."
I am not sure he could be of help and they are a competitor, but you could call him and ask what we do, how our designs work compared to line arrays etc.
We are not advertising / marketing based company like most but among the engineering and commercial sound area we are known, in the last 4 years, we have replaced line arrays in half of the country's largest stadiums and many other venues based on sound quality and uniformity of coverage using full range Synergy Horns.
If you have facebook, you can get a better idea what I do at work below or pick up the latest Handbook for Audio Engineers, I was asked to write the chapter on loudspeakers.

HAHAHA Tom you almost lost it this time with the contentious at times obnoxious and appropiately named INMATE51. Since the times of the disagreements with the Pi speakerīs owner in the early 2000s I have not seen you so angry !! Pay no mind to Inmate51 he uses this agravation technique to draw attention to himself but really respects you most of all otherwise he would not pick on you. I called him "grasshopper" in response to one his posts a long time ago because he reminded me of that young Kung Fu TV character. Seems like he is a young greenhorn in this field. I advised him not to jump too high but as expected he never listened and even with his grasshopper legs always ends up jumping too short.
In regards to advice for a reasonable size horn you gotten more than enough advice, I will only add that horn cabs especially those for home use can have the last section of the horn hinged so that in closed position they have better WAF and yet have very large mouths when opened up. I use this idea in most of my designs.
Lastly I remind you to try to keep to your companiesī "mission statement" although at times it can be very difficult.....yes luck with this one.
My regards
Rafaro
And it's 1 - 2 - 3 PIN! Congratulations, you won that one Tom! Some people are trolls, some are just asses, and some are both. Dave W. oh yeah... P.S. you are a better man than me when confronted like that. You seem to be a nice guy in addition to being a darn fine horn designer type person. Sorry, I don't know your proper title.
Everyone thinks I'm strange except my friends deep inside the earth
