Capacitors in Parallel. When two capacitors are placed in parallel, it is as if the area of the plates were increased, and the total capacity is increased. The current flow is therefore increased. Each parallel path consumes current according to its opposition to the current flow. Two equal-sized capacitors would each draw their normal current ...

Figure 2. (a) Capacitors in parallel. Each is connected directly to the voltage source just as if it were all alone, and so the total capacitance in parallel is just the sum of the individual capacitances. (b) The equivalent capacitor has a larger plate area and can therefore hold more charge than the individual capacitors.

In short: "high" capacitors (like the 1000 µF) are used to smoothen the voltage signal to a straight DC voltage, "low" capacitors (like the 0.1 µF) are used to suppress interference voltages. So the two capacitors have two different "jobs" to do and can not be replaced by one with the same capacitance.

These will have the greatest impact on sound. I use poly caps there, when I can. Shunt capacitors, wired in parallel to the woofers, can use NPE capacitors, since they''re usually connected to ground, and don''t influence the sound as greatly as the series parts. Finally, I like to use bypass capacitors.

By putting capacitors in parallel, the capacitances add. Usually this is good, because more capacitance resists voltage changes more strongly. $$ C_{effective} = C_1 + C_2 + C_3 $$ At the same time, parallel resistances or inductances are effectively decreased. The effective inductance (resistances are similar) of this circuit is
