Hello ppl, I now know that there are Crossovers with 12dB/Oct, 24dB/Oct, 48dB/Oct and some in between these values. Now I ask why? Is this because of the difference in response of some drivers? And how can it be that the phase gets 180 degrees turned when using passive xovers and most of the cheaper active xovers? My curiousity goes out especially to subwoofer integration, although I would also like to know how this applies to speakers and their circuitry. Anyway thanks in advance for answering this difficult matter!
