Capacitors are simple devices. They consist of layers of conductive material sandwiched between insulating materials. They work somewhat the opposite of the coil we discussed yesterday.
A coil passes DC (battery voltage) and low frequencies without restriction. A capacitor passes no DC, and signal begins to flow only as frequency rises.
The most common tweeter crossover circuit is a single capacitor inserted between the power amplifier and the tweeter. The point at which music starts to play depends on the tweeter and the size of the capacitor. The bigger the cap, the lower the frequency that passes.
And here's an area where quality matters.
Cheap speakers use cheap capacitors. Expensive speakers use expensive caps if they are to sound good.
