Pinking outside & crossover?

I was told to use the RTA Mic and auto eq outside before I try in a venue. My question is after I auto eq outside how do I fix the issues with my speakers by using the PEQ? My second question is when talking about crossover settings like 50hz
BW 24, what does the BW24 stand for?

    After auto EQing, look at the the plot of the GEQ. If there is a 4db boost at 63 hz and 2db boosted above and below it then on the PEQ add a bell with a boost of 4 db at 63 hz. You'll have to play with the Q to get the width right. You have 2 filters for the lo's and 3 for the highs. You'll have to pick which areas are most important to you if you have multiple problems. Sometimes to get the desired curve you have to add a cut right next to a boost. I like to refer to it as scientific guess work. After making the initial adjustments, flatten the GEQ and re-pink. Compare the change and keep making adjustments until; you are happy. If most of the bands in either x-over section need to be boosted or cut, either turn down a loud amp or adjust the gain in the x-over. If there is a boost or cut at the x-over point then try over lapping or seperating the slopes a bit. The BW 24 is the filter type and slope. Butterworth @ 24 db / octave. The type filter denotes the sharpness of the knee. Typically the steeper the slope at the x-over point the better.

    The goal is to get your system as flat as possible so that every venue you go into you have a place to start and you only have to deal with the room. The end result of the flattening session should be saved and never adjusted (in theory).
