If I knew how to properly phrase the question, I probably wouldn't need to ask it

The button multiplies the crossover frequency you have dialled in at the pot 10x ie if you set the pot to 250Hz and press the button the crossover frequency will be 10x 250 = 2500Hz.
You should know roughly (it will only be roughly anyway as cheap pots are typically +-20%!) what the crossover frequency should be and to achieve this frequency you will either need the 10x button or not. Thats it.
Should be explained in the manual, whats not explained in the manual is that you should get a better crossover then a Behringer. Your speakers deserve it!
Yes they ARE cheap pots! Can you direct me to better pots that fit the Behringer?
FYI, I had a Bryston, no big deal, but a lot more expensive! Marchand would not answer my question about XLR unit, so I opted for the el cheapo DBX, had to return it for repair because of bad pots, and got the Behringer to hold me over. I think the DBX sounds better, but does not have subwoofer outs
I'm sure you could find some suitable Penny&Giles ones but that would be a waste of perfectly good pots. Also they would probably cost as much as your entire xover each!
Personally I use two upgraded BSS FDS360s which use plug-in cards to set the xover frequency.
This is a much more precise way of doing things. The cards just carry the necessary caps and resistors to achieve the desired frequency and slope.
I bought the BSS's s/h (around £100 each or £700new) and then swapped the original 30 year old opamps (TL072) for something almost modern in the form of BurrBrown 2134s. I would like some really good opamps (like the latest offerings from National Semiconductor or Linear Technologies) but there are quite a few in there and I was lacking money.
The LabGruppen xover uses dip switches which is also ok and should be cheaper then Bryston.
When it comes to digital xovers I'd go for XTA, finances allowing.
