[QUOTE="leonm12, post: 4626305, member: 570626"] Hello, As I know, when the values of the slop at the crossover point are set at -12db/oct for both filters (Hi and Low pass), the phase reverse 180 degrees in the cut-off freq of the filter. and in this case, setting to reverse improves the connection between sounds. for example, If I set both crossover points to 80Hz at 12db/oct for the Woffer and the Subwoofer (while the subwoofer is facing the inside of the car like the the other elements- same direction), reverse the Sub or Woofers phase is needed. or in case the subwoofer is facing the outside of the car (the usual case), no need to reverse the phase of the elemets if using 12db/oct for both filters. my question - is it apply also for the connection between Woofers&Mids&TW? cureently - woofer High pass filter is set to - 900hz/12db-oct Mid high pass filter is set to 900hz/12db-oct Mid low pass filter is set to 4.5Khz/12db-oct TW high pass filter is set to 4.5Khz/12db-oct shoul I reverse the Mid's phase if I use also 12db-oct cut between all the elemets? please give me professional answers only if you really know about this case.
