Re: FIR filtersIn a linear system the magnitude and phase are directly related etc., the problem is not everything we are dealing with is linear.... also in a multi way system a resonance issues that is out of band e.g an octave below the crossover point, will have little impact on the magnitude and phase response but will be clearly heard by the listener. A corrective filter on the broad band input signal will not be able to solve this problem, it must be dealt with by the processing specifically assigned to that driver.To see that's happening in the time domain you need to look at plots like this ...
