I’d have thought it should be as simple as uploading the project file that you have saved on your computer (the one you reopen when continuing on with the project). So am I right by saying you are utilising the impedance plot of the drivers as well as the frequency response. If you haven’t don’t that yet, I’d highly recommend to do so. If you can’t get the file uploaded yet, could we see your frequency and impedance plots of your network? That’ll definitely help in analysis of your design 🙂
