Well, symmetrical is not really necessary but when you have a symmetrical (same fc and slope for both HP and LP) the equidistant placement gives you time alignment.
You can also tweak the XO to get an asymmetric 3rd order LP and 2nd order HP to roughly match up for group delay around the XO so they are compensating for the particular driver to listening point distances you want. Or you can do it the other way round and match the distances to the group delay in the XO filters.
You can also use REW (or DEQX which can also adjust for it) to measure relative delays on the driver outputs
