Hello 🙂
I simulated a closed Box design in Akabak and i also built it. My Impedance Graph in Akabak looks odd to me. Here yo u can see the LEM Page, with all the Parameters for the Driver.
The Values are all correct. Driver is B&C8BG51.
Here is the Impedance Graph, calculated by Akabak.
The Resonance frequenzy around 90Hz is fine but towards the higher Frequencies id expect a rise in Impedance. And that is what i measured in REW aswell.
I should add, since this could be the Problem. The only Impedance i can measure in Akabak is the Source Impedance. I assume it is the Impedance "seen" by the source but i may be wrong.
kind regards and a nice weekend

Exactly, and im wondering if i have to put any extra Parts into the LEM Page of Akabak since inductance and impedance are not taken into Account in the driver Parameters.
Ty for replying Lojzek 😀 you See im still on the Same Problem with the Same Speaker trying to understand a different Programm.

You should define a value for VC.
The value is set to 0 in your simulation.
Double click on VC and set the correct value and the MODEL.

Ok ill Check VC tomorrow Morning or tonight. I will let you know about the results. Thank you very much 🙂
Hello Elias.
Did you improve your simulation with the suggestion? I am curious because I was wondering the same.
Regards.

Hey Cesar, sorry that i didnt reply at all. I had so much work the past months that i did not have time to go on at the project. Now its starting to relax again an i opened Akabak today. I found it pretty hard to get the right values for the Models (Akabak or Klippel). Have to do some research the next some days. If you already got something, let me know 🙂
