What is SPL high and low impedance VituixCAD

Hi mule,


normally the input picture should look somehow like this:

Peerless_NE149W-04_(Frequency_response_+_Impedance).png



The impedance scale is on the right side of the graph.
You just proceed the same way as for the frequency responce.
The impedance curve is not mandatory for a simple (active) speaker design.

I am not sure I understand but just to show what I am thinking about, this small drawing.
Everything is hollow inside and the bass goes trough the bottom of the speaker cabinet tube.

Same as SPL. The SPL buttons and boxes are on the left and the impedance ones are on the right. Don't use them at the same time.

Don't forget to set linear or logarithmic scaling.
Oh thanks, so that's what I do wrong!
So first Import SPL and ignore impedance, then export that part.
After that, import impedance and trace that and export that as a separate file?
