Thread for Drivers with Semi Inductance

[StainlessSteve]

Measured and calculated the Eminence LAB12 and added it to my Drive list.

Has anyone measured the semi-inductance of the dayton nd105-8?
Thanks.

Parts Express makes the ZMA files available for the Dayton drivers on their website, so you could determine them yourself....

If anyone has the semi inductance params of the B&C 15DS100 or has that driver and could measure it it'd be greatly appreciated.

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'.

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!
