You DO need to know what the component values are because the crossovers are setup with different filter points for low-pass and high-pass. (This is especially true of the older models with parallel crossovers.)
And, a confirmation measurement of the impedance of the xducers should be incorporated as well.You can't just select a single crossover frequency for both portions and vary it. You'd end up with a hugely bumped up midrange response.
