millercarbon, you need to make up your mind. In regard to subwoofers you have stated that "time does not matter."
When it comes to crossovers it matters a lot. Group delays can be caused by positional factors and electronic factors. You can adjust any set of group delays to be exactly the same. This can be done by moving the slow drivers towards the listener or digitally delaying the early drivers to match the late ones. 1 ms = 1 foot (at sea level). I can usually tell something is wrong by 0.2 ms at low frequencies but have never blinded myself to this so it could be longer. I can tell the difference in bass impact but I am the one adjusting the delay. Of course I set them all to zero.
The vast majority of audiophiles do not have this capability which IMHO is a shame. It is vital for proper subwoofer management and imaging in general. It is the difference of hearing one vs two voices.
