Thank you all for your contributions! I've now got a better idea of what is going on.
Can resistors affect the phase? I thought only caps and coils where involved here? Something you can clarify?

Resistors are phase neutral. The current neither leads or lags the voltage.

The builder is making very fine adjustments to the crossovers. Again, we have to trust that he knew what he was doing. I also suspect this is not the crossover he started out with. I suspect he started with the basic, tested, redesign, refined, and tested again, the redesigned and refined until he got the result he was looking for.

The resistor will subtly change the transfer function of the filter and this will also affect the phase. The effect on the actual spl curve may not look that great but it's what happens with the phase that is interesting. I've found that a resistor inserted into a shunt leg like this (and tuned appropriately) can make the difference between poor and good phase matching at the crossover frequency.
