It's not quite that simple. The length of the horn is determined by the ratio of the size of the throat to the mouth for a given low frequency response. While the size of the throat is less "scientific," the size of the mouth is calculated based on the desired low frequency response. So, in my case, the driver "falls way off" at 80Hz because it is a design parameter. You can't just say, oh, well, I'll make this mouth bigger or smaller or whatever without other parameters being affected. I mean, you can, by a little, say, in exchange for horn efficiency. But I wouldn't cut corners unless there was a compelling reason. Some of the wave will bounce back regardless of the low frequency response and the 45 degrees pyramid at the bottom is there to counteract that and guide the wave out. In a sub it really doesn't matter all that much, but in a mid bass horn it sure does.
