Calculate Xmax

[Radew]

The excursion can still be plotted as in post #11.

And how do I make that graph?

I used excel, but any spreadsheet tool or even paper and pencil should work!

The speakers have a port hole.

Maybe but a small port on the back isn't the same as the driver on the bench.

but how? Sorry to bother you, but my question is literally how do I do it, what do I have to do?

hi @Radew

you fill in two columns with data pairs in the rows:

• Column 1 with input voltage
• Column 2 with corresponding excursion

Then you mark the data fields and create a "scatter plot":

• Column 1 defines the x value (voltage) of a data pair point
• Column 2 defines the y value (excursion) of the data pair point

Keeping the values in a ascending order and connecting the points (with straight or curved lines) creates a readable plot.

Have a look here:

Thank you very much, now I understand, I will try it
