PS: Do you have a proper workflow how to achieve a 2- or 3-way System with a linear phase from about 100 Hz to 15 kHz? I tried to use several possibilities whit the filters (HP and LP, lin, min. max.phase) and I always had the behavior like I described further above or I can’t get a linear phase for the hole system. in the FIR Filter generating programs you can adjust the phase over all at the end. I have there results whit a proper step response an a linear phase.
Thanks and best regards to Australia!
