Resistors get hot and are used to attenuate speakers { in some instances }, a capacitor of the correct size for the ohmage of your driver will serve as a highpass filter .

An inductor [ or coil ]serves as a lowpass filter ]

People who don't put a cap on their positive wire have been known to damage their tweeters.

I have that issue but I don't like pulling those older issues out...I'd rather read online.
