John K's Nonlinearcompliance

[shrub0]

I'm wondering if anyone has played around with John Kreskovsky nonlinear compliance excel spreadsheet. I can't get the distortion chart to work in excel 2013. Also what can be learned by the graphs? Is there certain t/s parameters that result in lowered distortion once the driver is in a sealed box?

Also, can I use klippel data to input a compliance shape factor.

Thanks.
