[QUOTE="Jakerrr, post: 8442582, member: 637923"] Ok, so I've been researching a lot about crossovers. It seems like there are 2 schools of thought, the 1st one being less popular, but it was "keep hope alive" who said it: 1) Each order (6dB) adds 60 degrees to the phase. 2) 1st order (-6dB/octave) does not change phase, 2nd order (-12dB/octave) flips phase 180 degrees, and 3rd and 4th change phase minimally. Also I've read contradicting information as to whether electronic/active crossovers switch phase just like passives. The only thing that seems universal is that 2nd order (-12dB/oct) flips phase 180 degrees. Can anyone help clear some of this up for me? The main thing I'm most concerned with, is this: If my passive crossover for my mid and tweet is low/high pass 12/12 dB octave, ignoring other variables, my tweet and midbass will be in phase because they've BOTH been flipped 180 degrees out of phase by the crossover, right? Because a lot of people say you need to reverse the polarity on either the tweets or the mids, not both, in order to have them in phase. I'm so confused... [/QUOTE]
