[QUOTE="Peter Morris, post: 201735, member: 652"] You must take care with that approach each driver must behave correctly in terms of amplitude at time and it must do that beyond the crossover points. You can fix things that are in the middle pass-band with a global filter, but where the correction will impact the adjacent band you can have an issue. I will try and explain a little more If you have a linear system and it has a peak in the response some where you will see a corresponding behaviour in the time domain waterfall plot or whatever you use. If you apply the correct EQ to fix the peak you also fix things in the time domain. If this occurs near or at the crossover point you are effectively modifying two pass-bands. One that may not need correction; and the one that does need correction will not be corrected enough. If they summed perfectly all would be well, but usually thats not the case. The results can be an amplitude response thats looks fine but there can be audible issues in the time domain. [/QUOTE]
