B-36-MF plans/hornresp help

[Niclas L Seifen]

Hello everybody,



I just gotten my hands on one of these rather odd CW boxes.
I've made a 3d model of the box, but i need some help with the hornresp paramters.


All i could figure out is that the rear chamber is ~90.13 Liters.



Here is the file:
B36-MF


Thanks in advance
