So if I buy (or design, but I would prefer to buy) an 800Hz crossover, then I assume the two should work together, but how does one balance the two drivers sound-level wise? (I assume that this is what is meant by using compensation.) Is it simply a matter of experimentation by adding resistance in series with the 4592? If so, do I just order some resistors from Parts Express and then try them? If so, what wattage should they be, and what variation of ohmage? I have quite a few large ceramic resistors left over from my slot-car days; I suspect that I could experiment with these.

I know that this has already been done with the kits that Wayne sells, but how does this get done from scratch?

(My original plans were different or I would just buy a kit.)
