Agree, however often the best course of action in this case is implementimg an all-pass filter which will still keep things 100% Time-aligned but allow one to get things 100% In-phase and therefore a supurb Frequency response (as was stated and I agree, Frequency response is King). Of course if one doesn't have the option/means of implementing an all-pass filter, then doing exactly as stated here is the next best thing (and very effective).
You should not rely on those algorithms to do your bass. Do the bass stuff like we've done in the old days, balance levels, phase and delay for each sub individually with the others off and eq correct with the MAIN SPEAKERS. Repeat for each sub. You do this with kick drum getting the time alignment correct for each individualy as you were only using that particular subwoofer for two channel stereo. Once you're done, then all subs should be time aligned and in phase with each other. You'll need to confirm this by flipping the phase switch on each sub looking for holes and dropouts. If nothing changes and you have them all balanced from the crossover all the way down to your lowest frequencies, you're good! This takes allot of time but in the end, all your subs will be time aligned and in phase. Use the algorithms to balance and eq your mids and highs.

If you can get the front sub out of phase with the back sub, can you have your front speakers out of phase with your rear speakers? How do you fix it?
