Protection capacitor for tweeter in active speaker
Andrew, the filter point introduced by the capacitor should be at least 2 octaves away from the actual crossover point. If the value of the capacitor is to small it will cause phase shift problems. So for a crossover point at 3 kHz you would need for an 8 Ohm tweet a capacitor of at least 26.5 uF and for a 4 Ohm one double that.
