So for my next setup I think I would like to build a custom subwoofer from scratch. I found suppliers for all the parts I will need, however now I just need some type of software to simulate different motor designs. I need to see how making the top plate thicker, increasing the width of the gap, etc. will change the magnetic field and how it interacts with the coil.
Or, does anyone has the exact specifications for well known motors such as the TC9 and others? Specs like the gap width/height, and any other spec used on the motor?
