    I know nothing about electronics but I just realized that the capacitor is probably a "high pass filter" and has no affect on the woofer.

    The link you posted seems to be for an earlier L88 model. I posted the same schematic in post #4 just for comparison. Compare it to the photo I posted, they are completely different crossovers.
