What I'm trying to figure out is, why does the step response show the ES180TiA driver as if it is connected out of phase. The other driver is another woofer (DC200) that I added just to see if its step response would be shown inverted, but it isn't. So I think Dayton may have generated the FRD...

Can anyone comment on why the Dayton ES180TiA step response is inverted? I am using Xsim and I have two different speakers hooked up, one is a Dayton DC200 (blue curve in the step response graph) and an ES180TiA (shown in red). I am using the FRD and ZMA files provided by the Parts Express...
