Thanks for your post and included link. I personally didn't want to reenter it anymore, until knowing the why, but for me it's OK.
I could reenter it here in the Studiotips files directory as well.
I did not enter new data on the net, and I used it in a transformative educational manner, respecting the original name of designer and studio.

This 80 Hz is rather common for better systems. (Genelec has settings for 80 and 120 Hz I believe).
But since these low frequencies can be rather disturbing via the mains (modal bahavior, interference) there is a plus and a minus involved in shifting this crossover higher. The higher the easier to control acoustics with treatment, even at the possible (not necessary) expense of low frequent localization info.
