Hi!



Does anyone know how to sim a stepped horn? I’ve tried with hornresp, but it doesn’t seem to have a stepped horn option. I want to try designing a mini scoop but avoiding weird angles when folding the horn, just to keep it simple. There seems to be general agreement that mini scoops are just bass reflex designs, so I thought that going for a bass reflex with kind of a laberynth port with different vent widths / stepped horn should’t make a big difference on low end and SPL vs. going for a normal horn.


Thanks in advance!
 
Something like that ???
Stepped segment is activated double clicking on one of "S1" to "S5" on main input screen. It only work using Tool=>loudspeaker wizard. Not using Calculate button.
