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 results are close to the same. I have the room to build either one. Is there something I am missing? Which is actually better and why?
