Should we be entering an "average" voice coil operating temp to get a more accurate model or is it insignificant?

The voice coil temp only matters when putting a lot of power into the driver. At low power levels, the voice coil heating is going to be less than at high power levels.

It should also be noted that the voice coil temp calculation in WinISD creates extra SPL that isn't real. I believe the frequency response shifts are relatively accurate, but the power compression needs to be manually added.
