I see. So when you find the correct level how are you supposed to know the resistance of the Lpad to use in the actual crossover? Or do you just have to remember what it sounded/measured like adn swap in resistors until you find it again?- Bottom

That's a variable L-pad.
This is a fixed version

Adjust the variable unit to the output level you want. Then cut it out of the circuit being careful not to move the dial. Now measure the values of the resistors and make the fixed resistor one. Or leave the variable one in place..
