See, thats what led me to believe the unit was in fact exponetialy ported. Seeing as how I have built one and it has raised sensitivty by 19db minimum over driver's suggested SPL output.
So how woudl I use WinISD to calculate the horn asa port? because it has two different lengths with infinite lengths between, shoudl I just do two runs at the shortest and longest and assume the enclosure is ported between the two?
