[mledez]

Hi,

I decided to change my sub (Image Dynamics ID12D2 V3), So I bought Focal 40 V1 16" Driver...

Taking a look at the user manual I noted the suggested aplication values.. All number in liters and Hz

Fast and Tight Bass 40L Fb 25 F3 46
Punchy and Dynamic Bass 50L Fb 23 F3 43
Deep and Articulate Bass 60L Fb 20 F3 40



So I decided to check the curves and make some changes to create my new box... But WTF

The curves in WinISD are exactly ass focal but BassBox and WinISD Pro show me something very rare

What's happening???

The green line is my model
