Post Subject: Mid-bass Hornresp (V51.30) simulationsPosted by koh123 on: 5/20/2021

I am going to show two different simulations for a 105Hz tractrix horn with the same 8”driver (B&C 8PE21).  The parameter values for these two simulations are quite different.   However the simulations predict the same great flat freq response within the range I am interested in (150-800Hz).  The diaphragm displacements are different as to be expected from s1. The first simulations values are close to InlowSound.com 135Hz mid-bass.  And the second simulations values are close to Aries Cerat model Contendo Reference.  I am at a loss as to how different the two sets of values are but the freq results are close to the same.  I have the room to build either one.  Is there something I am missing?  Phase? Time alignment? Which is actually the better one and why?
