Thanks for the correction. Didn't mean to spread misinmormation.

This mathcad is is way above my comprehension level.
The WinISD was easy enough with the Thiele/Small Parameters.
The input for mathcad doesn't make any sense to me.
If someone with experience with this software would like to help me out, I would be very greatful.

My bad, didn't read the notes, thanks anyway.
If I get stuck again I'll let you know.

"One final note, the notation used for the Thiele/Small parameters in my MathCad worksheets is a little bit different. When I first started studying speaker design theory, I decided I did not like the subscripts used in the original AES papers so I translated them into my own subscript convention. I changed the "s" subscript to a "d" subscript for all of the variables. This change exists in all of my personal notes and MathCad worksheets created over the past 20 years. At some point I will buckle under and conform to the generally accepted convention, but for right now all I can offer is the following translation. I know that this has caused some confusion for a few people and I appologize for any inconvenience."
