Winisd 0.70.900 Sim with or without LE

[FE3T]

I know these programs say little about a drivers behavior at higher frequencies, but I wonder a bit about LE and the parameters impact on a speakers usability at the high end.

Lets say I want to use a speaker as a low mid. from 80hz-1khz, But according to Winisd the driver are 7db down at 1khz IF LE are added to the simulation, EVEN if the manufacturers spec sheet show relatively linear response well past 1khz

Do I trust Winisd and find a different driver or do I trust the manufacturers specs and stop using the "sim with LE" feature in Winisd?

Hi, it seems to me that WinISD is just taking into account the Le, & therefore makes no account for cone breakup & resonances & associated distortions etc etc.
