can use different types of filters and different order for those filters:
• Bessel order 2, 3 and 4;
• Linkwitz-Riley order 2, 4, 6 and 8;
• Butterworth order 1, 2, 3, 4, 6 and 8.
The into Apply button is highlighted as soon as a parameter is modified. If you don’t click on it, the changes will not
be taken into account in the calibration of the crossover.
If the changes are unwanted, press the Cancel Changes button to cancel your modifications.
The theoretical model of the specified filters is represented as follows:
• The green curve represents the theoretical low-pass filter response
• The red curve represents the theoretical high-pass filter response
• The blue curve represents the theoretical hi-pass and low pass filter for the Mid speaker in a tri-amplification. It will repre-
sent the theoretical hi-pass and low pass filter for the LMid speaker in a quadri-amplification
• The purple curve represents the theoretical hi-pass and low pass filter for the HMid speaker in a quadri-amplification
• The yellow line represents the theoretical resulting in the blue, red and green curves.
You can zoom on the curve by using the wheel of your mouse. You can also click on the graph and move the mouse
to see other parts of the graph.
