The only published impedance data I could find was from the BC website which only had impedance for 20Hz and above, so an assumption has to be made for Re'.

15DS100 LF Drivers - B&C Speakers
Using rule of thumb (setting Re' = Re*1.1) and removing Re' from the least squares list, a good fit is obtained with the published impedance data for both 4 ohm and 8 ohm versions.
Values from the BC datasheets were used for Sd and VAS.
Attached are exported Semi-Le datasheets and Hornresp driver files for both.

i'm currently working on a tapped horn using this driver and this helps me greatly, thanks!The only published impedance data I could find was from the BC website which only had impedance for 20Hz and above, so an assumption has to be made for Re'.
