Hello
I have 2 Dynaudio Contour 2 loudspeakers and I simulated their crossover with VituixCad software (very well done, congratulations!). I don't understand why if I connect the 3 speakers with the same phase (as all theories say for a 1st order filter) a deep depression at 1400hz is highlighted !!! If I invert the polarity of the mid-range the response improves! See attached diagram.
Thank you

Your filters are not electrical first order. You have series and parallel elements in your crossover, therefore the reason to invert the driver polarity to maintain phase relationship.
Dynaudio Contour improvement
Name of this thread must be changed to e.g. Dynaudio Contour improvement. VituixCAD thread already exists and must be kept individual.
Driver measurements are not taken according instructions so not much hope for improvement.
Electrically 1st order XO produces usually 2nd order acoustical slopes due to natural acoustical slopes of drivers so mid should be inverted in practice.

kimmosto, how do i change the thread name? Also what do you mean by "Driver measurements are not taken according instructions"?
Is this truly Dynaudio Contour 2 original x/o schematic?
Inductor dcr values are probably a default software setting.
off topic: why does forum software shift two rows for just one enter click?
I always need to shift rows higher to get it like I wanted it in the first place.
