What is the electric field in a parallel plate capacitor?
When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is $${bf E}=frac{sigma}{2epsilon_0}hat{n.}$$ The factor of two in the denominator comes from the fact that there is a surface charge density on both sides of the (very thin) plates.

Science of "bypass capacitors" in crossovers | diyAudio
My MG1.6s have four parallel capacitors on the quasi-ribbon tweeter: 10uF, 6.8uF, 5.1uF, and 0.1uF. The 0.1uF capacitor ensures that the impedance does not rise at ultrasonic frequencies. That may have been problematic for some amplifiers. The crossover also has a 4A fuse that can only be blown by an amplifier going unstable.

capacitor" too hi or low enough"
on start capacitors 10% variation won''t be a problem. But on RUN capacitors the mfd should not vary (can go up on voltage but mfd should be same) Get Copeland''s electrical handbook and learn how to combine Capacitors in parralel and series so you can always provide proper mfd:
Capacitors in Parallel
The voltage across capacitors connected in parallel is the same for each capacitor. If you know that there is 5V across one capacitor, it means that all the other capacitors that are connected in parallel with this also have 5V across. This isn''t specific to capacitors. Any type of component in parallel will have the same voltage for all the ...
