Hi everybody, i am currently working on a Jubilee style project: 2 horn crossed at 500Hz. After extensive research to find the good driver, I went to an Audax PR300M0 (Fs 17Hz, Qts 0.26) and started simulations on Hornresp. You will find below two simulations of front horn loaded, closed chamber. One has a hyperbolic expansion, the other one is more atypical with a narrowing after first expansion. This intrigues me with its unconventional shape while it offers a much wider and smoother response curve in the low frequencies with a small loss of sensitivity (driver, chamber volume, surface Sd, horn length are identical for the 2 simulations). I turn to you for advices: should I trust the Hornresp simulation? Should I focus on this narrowed expansion which seems to provide a 1 Pi response from 40Hz to 500Hz with a single 12' driver? Thank you in advance for your advice
