Five protections for capacitor cabinet
This will ensure that the protection capacitor does not effect the crossover frequency response by too much. Large plastic capacitors can be expensive, but are cheaper than replacing expensive compression driver diaphrams. I would connect one capacitor, and 2 light bulbs in series with each tweeter. I would not use the resistor. - Download [PDF]
