Simply becuase those capacitors are in parallel with the woofer voice coil = the signal to voice coil does not pass thru them therefore they will have little effect on the sound produced by the voice coil. The tweeter capacitors DO pass signal direct to the tweeter voice coil however, that is WHY you should replace these 1st (if replacing any). Capacitors block low frequencys & pass high frequencies. Inductors (coils) pass low frequencies & block high frequencies. In the woofer filter circut, the inductor passes low frequncies to the woofer, blocking higher frequencies, & the additional capacitor siphons off those higher frequencies the inductor missed. In the tweeter circut, capacitors block dangerous low frequencies from the fragile tweeter & additional inductors siphon off low freqencies that make it thru those capacitors. Since no series crossover part cuts off frequencies abruptly like a brick wall, the additional parallel components are helpful in blocking unwanted frequencies. DO not damage the original parts in the event you do not care for the new voicing different parts will impart; in that way you can return to the original sound by putting the original parts back in. Exchanging crossover parts will not nor cannot increase sensitivity (more responsive @ lower Volume).
