An excerpt from Pioneer's Understanding High Fidelity..... "Protection of tweeters against bass pulses: strong, sudden bass pulses may occur when the power amplifiers are turned on and off, and these could damage the tweeters. As protection, a capacitor of approximately 6-12uF should be inserted (in series) between high range amplifier and tweeter." My questions: What voltage rating should this cap be? Should be electrolytic, correct? Polar or non-polar?
