The output of the straight mid bass horn is very linear. It goes up to 500 Hz before rolling off and down to 80Hz at which point it begins to drop off like a rock. The x-over is first order 500Hz although recent listening test suggested that 4th order may offer some advantages.

That's a very good FR. More than two and half octaves. I wonder how it sounds from 400 to 500hz? I llke that you say it's linear. Really for yours to go down to 80hz is surprising. It doesn't look that long/tall. Even with the stands it doesn't look that tall. Long xmax driver?
Do you know the efficiency?
Boy, crossover slopes are a subject. They will have to wait, as it's bedtime on a work night.

Big speakers and little amps blew my mind!
The beauty of the floor firing horn is that the entire open area on three sides is the mouth and is equal to about 560 sq inches. The total length of this particular 80Hz horn is 38 inches whereby the body is only 30 inches long and the last 8 inches is the distance from the bottom edge to the mouth. This arrangement allows for a very compact speaker. And, yes, it is remarkably linear. I should ask Bruce if he saved the data somewhere in the data base of his computer after we took the measurements.
