Hi guys..

Best regards - Frank

You can partly sim as compound horn in hornresp.


Or sim Vtc as rear volume. Atc few times Sd. All sim as Nd. Horn segments will be than like port.
Vrc 1, Lrc 0.01, Ap  larger than Sd, Lpt 0.01

Before i go further with it, does it give any positive gain on the performance, or is it a waste of time?
Maybe better just to go with a Radius 25-30mm flare on each end to help with port turbulence, as the main goal is.
