With an uncorrected mass corner around 433Hz, this is way too high for me, so I guess it's a 'different strokes for different folks' situation. FR tech forum gallery? Anyway, if you plot out what I posted you'll see that until you get near the mouth of the full size horn, which you wouldn't since the cutoff would be at a much higher frequency, the expansion is conical enough that I'd bet dollars to donuts you couldn't hear the difference outdoors, much less in a typical room.

Hmm, I saw your horn dwgs, but didn't see any specs for them. Understand the problem well, I've lost 30 lbs since I saw the Atla DIY2003 Meet pics. Still got another 25 to go though, ugh! Oh well, I enjoyed getting them, but as usual, payback is a !@#$%^. GM

Arg! Didn't scroll down far enough. I have the fonts set so large I have to scroll pretty far just to get to the bottom of the horns section. Anyway, the point I was trying to make is that if you draw a line between the throat and at the 42.8" point and built it that way, you would be hard pressed to hear the difference. Now if a slower flare rate is used such that this slow expansion went all the way out to 1/4WL before a rapid flare to the mouth, it will work just fine if it's a straight line, i.e. conical out to this point. GM PS - I prefer cinnamon and sugar syrup on my rice cakes. ;^)
