I am trying to model a sub and for the life of me I cannot get this error to stop. I went back and followed a suggestion by LTD02 to enter what I have and tab through what I don't. It still says driver data fails integrity check. Can I get accurate results despite this, or what should I do?

The sub I am trying to model is an Alpine SWS-15D2

every now and then, a driver throws errors even when the t/s parameters are good. such isn't the case here though. perhaps one or more of your units is off. to change the units, just click on it and it will cycle through. green are values that I entered. blue are autocalcs.

 

Thank you @LTD02. I was entering what I found in the manual and tabbing the rest. Here is what it gave me. It looks like I was using different units for Cms and Dd. Also, I notice you entered 1000 in Pe, which I did not have. I went back and tried again, but it still goes in crazy. I am using your parameters now, but can you tell what I was doing wrong from this pic? Always looking to learn. Thanks.

several t/s parameters are linked by equations that is what allows the program to calculate certain values based ones that you enter. if you manually enter values that don't exactly match the equations, winisd will indicate an error, even if the difference is 0.000001.


based on the green values that I entered, winisd calculated fs=27.02. if you manually plug in 27.03 in that cell, it will indicate an error, even though there is no practical difference between 27.02 and 27.03.

 

Clear the Qts box, Qts is auto calculated from Qes and Qms. You can't enter Qms Qes and Qts at the same time as rounding errors will create differences that cause the program to throw an error.

 

This works! Thanks!

Try using this tutorial. A friend of mine posted it on a car audio forum. Worked good for me. He even tells you which parameters to enter.

 

I tried the fixes here and still get the failed integrity check:

I originally manually entered the Qts, Fs, and SPL that had been calculated different from the advertised specs, so I deleted Qts, Fs, and SPL and tabbed through the parameters to let it calculate those. I still get the error. This is for a Sound Integrity HS-24:

 

Remove Qes and let it auto calculate that.
Edit, Vas as well.

Assuming the driver I'm interested in modeling lists all these parameters in the spec sheet I personally enter only: Mms, Cms, Re, BL, Le, Sd, Xmax, Pe and Qms. The order in which they are entered does not matter.
