But there are somethings inside in the capacitor not like the symbol is empty , that things make AC pass in different speeds of different frequencies, that will make sound quality change

What is DC, it is AC with a frequency of 0.
If the frequency increases it becomes less and less like DC.
So a cap functions as a high pass filter.
Look like I invented the crossover!
I want to add copper /silver (air ) coils , they form a resistence for AC through selfinduction so simply said they filter out the low freqs by blocking high freqs , the lower the freq the lower the resistance .
Together with the above caps they form the basis of crossover freq tuning , you ll find them in almost any LS .
Core coils needs lesser windings to reach the same induction as compared to air core coils, but have also a disadvantage
