I asked this question to Chris K. and posted his response somewhere, but for the life I cannot locate it using search. His response was that the filters themselves are not altered by the choice of crossover values in Pro. When I asked him what was meant by the Pro message "Finalizing filters..." after the crossover selection was made, he said something that I cannot recall, other than it wasn't changing the filters in any way. I thought we had agreed to add Chris' response to the Pro FAQ, BICBW. Regardless, a search of the FAQ doesn't find an answer.
Thanks Jerry. I will add it to the Pro FAQ even though I don't quite understand it ;)
What do you think is the point of having ranked, user-selectable crossovers if the filters aren't changed depending on which XO you select?
Does it mean that by selecting my XO of choice (usually it's about 4th on the list and they are ranked in order of preference AIUI) that I am therefore at no disadvantage compared with choosing the first-ranked option? I hope so!
