Coming from a current career in live sound, and building DIY loudspeakers throughout my life... the rabbit hole I've gone down with phase and time-aligning speakers is a completely different approach, which is crazy to realize. With the live music stuff yes; fidelity, response, accuracy, and efficiency are the ultimate goals. Still, I've watched and experienced the emotion of a performance disappearing from loudspeakers aiming to achieve a perfect response curve. I have even watched crowds stop dancing and leave from being disconnected from the performance because of the "surgical" chase for perfection in sound reproduction. In those environments, it seems people want to feel the music more than accurately hear it if that makes any sense. My theory is that at loud volumes, high frequencies are just hard to marathon through from the underlying harshness of loud music due to most people's ears being still sensitive enough to feel the abuse of overloading the sensitive frequencies range for the ears... But for the low-end side of things, this video gave me the idea for a venue where I recently installed some speakers. I want to try and space the subs around the dance floor to spread the SPL across a broader area instead of creating a traditional sub wall and pounding the audience with energy. If the same feeling for the music's punching energy be achieved with... say a four-point (only subs scattered around the space) system to lower overall SPL but give perceived loudness and sane overall energy output then this would be a great experiment to try from this newfound knowledge and perspective towards the physics of sonics. GREAT VIDEO!
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?
